SMURFING (SFRM) HURRICANE DEAN

"Smurfs" Vs. Hurricane Dean

WIRED
By David Axe

August 19, 2007 | 9:54:06 PM

Two years ago Hurricane Katrina kicked the U.S. government's ass. Now, as Hurricane Dean sweeps past Jamaica on its way to the U.S. Gulf Coast, FEMA, the Coast Guard and the other military services are poised to prove they can do better the second time around. The military response actually began days ago when the Air Force's WC-130J hurricane-hunting patrol planes deployed brand-new sensors to more accurately predict when and where Dean will hit and what kind of damage it will do, according to the service. The "Stepped-Frequency Microwave Radiometer," or "smurf,"

allows the Citizen Airmen of the Hurricane Hunters to constantly measure surface winds directly below the aircraft. The smurf can also determine rainfall rates within a storm system. This, in addition to wind speeds at flight level, provides structural detail of the storm. "The SFMR will be the biggest advance I can think of to improve hurricane intensity forecasts," said Max Mayfield, former director of the [National Hurrican Center].

The data collected by the Hurricane Hunters increase the accuracy of the NHC forecast by 30 percent, a rate which will undoubtedly increase with the use of the smurf. This data enables the NHC to more accurately predict the path of storms in order to save lives and narrow areas of evacuation, according to NHC forecasters.

STEPPED-FREQUENCY MICROWAVE RADIOMETER
SFMR Ready for 2007

PURPOSE:

The Stepped-Frequency Microwave Radiometer is a state-of-the-art instrument designed to continuously and accurately measure the winds at the ocean's surface directly below the aircraft. The SFMR, affectionately known as "smurf", is installed on the WC-130J within a pod attached to the aircraft's wing. As the plane flies through a storm, the SFMR senses microwave radiation naturally emitted from foam created on the sea by winds at the surface. Computers then determine wind speeds based on the levels of microwave radiation detected. Currently, winds are extrapolated from the winds at the aircraft's altitude or from a dropsonde released from the aircraft, however, the SFMR directly measures the surface winds and is not confined to a single point like the dropsonde. This constant measurement of surface winds gives the National Hurricane Center a more complete picture of the storm.

The SFMR can also determine rainfall rates within a storm system. This, in addition to wind speeds at flight level, provide structural detail of the storm.

Two Hurricane Hunter aircraft will be equipped with the SFMR by the end of June with one added each month until all 10 WC-130J aircraft are outfitted with the SFMR pod, the last to be equipped in March, 2008.

WP-3D Stepped Frequency Microwave Radiometer (SFMR)


Measurement of the hurricane surface wind field, and in particular the estimation of wind maxima, has long been a requirement of the Tropical Prediction Center/OAR. The NOAA/Hurricane Research Division's Stepped-Frequency Microwave Radiometer (SFMR) is the prototype for a new generation of airborne remote sensing instruments designed for operational surface wind estimation in hurricanes.

The SFMR has a downward pointing antenna which passively reads the microwave radiation coming from the ocean surface. By making assumptions about the vertical structure of the atmosphere together with sea surface temperature measurements by a downward-looking airborne infrared radiometer, reasonable estimates of the ocean surface brightness temperature can be made at six frequencies between 4.6 and 7.2 GHz. Wind speeds are then calculated assuming linear increase in wind speed with these brightness temperatures. Since some of the frequencies are more attenuated by rainfall than others, an estimate of the rainfall rate below the airplane can also be made.

NOAA/NWS SEVERE WEATHER WARNINGS TO PROVIDE MORE PRECISE LOCATION THIS FALL, COMING OCTOBER 2007

NOAA NATIONAL WEATHER SERVICE SEVERE WEATHER WARNINGS TO PROVIDE MORE PRECISE LOCATION THIS FALL

NOAA image of NOAA Storm-based Warnings by county versus the more geographically specific locations due to take effect in October 2007.Jan. 16, 2007 — The NOAA National Weather Service will introduce this fall storm-based warnings for tornadoes, severe thunderstorms, flash floods and marine hazards that are more geographically specific for these short-duration weather events. Currently, such warnings are issued county wide. (Click NOAA image for larger view of NOAA Storm-based Warnings by county versus the more geographically specific locations due to take effect in October 2007. Please credit “NOAA.”)

"Weather doesn't follow geopolitical boundaries," said retired Air Force Brig. Gen. David L. Johnson, director of the NOAA National Weather Service. "Storm-based warnings provide the public with more specific information about the location of severe weather and the direction it is expected to move. Seconds count during tornadoes and flash floods. We want to provide the public with the most accurate description of what's happening in their neighborhood. We also want to avoid warning non-threatened portions of the county."

When issuing a warning, the NOAA National Weather Service will specify areas within a county and refer to commonly known landmarks such as highways or rivers.

NOAA image of the improved NOAA Storm-based Warnings due to take effect in October 2007."This is a fundamental change in our warning procedures and a major enhancement in our service capability," said Johnson. "Storm-based warnings will drastically improve graphical displays and empower the private sector to easily distribute the information through Web-enabled PDAs, cell phone alerts, pagers and other technologies. Communicating severe weather threats in this way is imperative in today's digital world." (Click NOAA image for larger view of the improved NOAA Storm-based Warnings due to take effect in October 2007. Please credit “NOAA.”)

The new warnings will take effect October 1, 2007.

NOAA, an agency of the U.S. Commerce Department, is celebrating 200 years of science and service to the nation. From the establishment of the Survey of the Coast in 1807 by Thomas Jefferson to the formation of the Weather Bureau and the Bureau of Commercial Fisheries in the 1870s, much of America's scientific heritage is rooted in NOAA. NOAA is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of the nation's coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with its federal partners, more than 60 countries and the European Commission to develop a global monitoring network that is as integrated as the planet it observes, predicts and protects.

Fourth In A Series - Waves

Introduction

The roughness of the oceans has important consequences for seafarers and coastal communities, and is linked to the global climate system through atmospheric circulation and winds. Satellite altimetry brought a global perspective on ocean wave climate (Chelton et al., 1981). With the accumulation of lengthy and carefully validated datasets from a number of satellite altimeters, it is now possible to evaluate the seasonality and inter-annual variability of wave climate globally to a resolution of the order of 100km.

Measuring Waves with Satellite Altimeters

By convention, significant wave height is defined to be four times the root-mean-square elevation of the sea surface, and is a standard statistic for the roughness of the sea surface. Satellite altimeters measure the roughness of the sea through the blurring of the leading edge of the reflected pulses by the uneven surface. Altimeter estimates of significant wave height are corrected by calibration with high-quality buoy data (Challenor and Cotton, 2001). Altimeters only measure the roughness of the sea in a small footprint (~10km diameter) immediately below the satellite. The data sampling is sparse, but sufficient to establish monthly mean significant wave heights on a 2o latitude by 2o longitude grid, or better if more than one satellite is operational. The gridded data sets are constructed from median values of individual "passes" across each grid box. Wave heights vary rapidly close to coasts. Also, the altimeter cannot measure waves if its footprint overlaps land. Therefore, the gridded altimeter datasets provide an offshore climatology only. Data along individual satellite passes can be analysed to extend analysis nearer shore, but even then the sizeable footprint of the altimeters is a limitation. Other methods are necessary to describe waves within 10km of the coastline.

Global Wave Climatology

Average significant wave height can be measured monthly over the globe by satellite altimeter. Wave height varies regionally and seasonally, monthly means mostly varying between 1 metre and 5 metres. Generally, the sea is rougher at high latitudes (North and South) than in the tropics. Wave climate in the extra-tropical North Pacific and North Atlantic is especially seasonal with much rougher conditions in the northern (boreal) winter than in the summer. The Southern Ocean is roughest in the southern (austral) winter, but is very rough throughout the year. Nearer the equator, larger waves can be either swell propagating from higher latitudes, or can be the result of seasonal winds (e.g., monsoons and tropical storms). The Arabian Sea is particularly rough from June to August coinciding with the Southwest Monsoon.

The seasonal and regional wave climate can be summarised by fitting a sinusoidal function of annual period to the monthly mean significant wave heights for each grid square. At each location, the seasonality can be represented by the annual mean, the timing of the maximum wave height (phase of the sinusoid) and the range (twice the amplitude of the sinusoid).

Global Seasonality of Waves. Top: Annual Mean (metres); Middle: Annual Range (metres); Bottom: Phase (peak in months)

North Atlantic and British Isles

There is evidence that the North Atlantic Ocean grew considerably rougher between the 1960s and 1980s, during the age of the ocean weather ships, at least at a few isolated stations (Bacon and Carter, 1991). Is this natural variability or global warming? A new perspective is brought by analysis of satellite data.

The seasonality of wave climate around the British Isles is derived from monthly gridded altimeter measurements over five complete years (1993-1997). The ocean relatively rough throughout the year, while more sheltered regions, for example around south east England, are relatively calm. The seasonality varies slightly from region to region. For example, the spring tends to be slightly rougher than the autumn to the north west of the British Isles, but the reverse is generally true in the North Sea and the Southwest Approaches.

Seasonality of wave climate around the UK

The seasonal cycle is a fair representation of the average climate in the 1990s. However, there is also a great deal of variability about the mean in individual years. This is especially true during the winter months in the Atlantic and Atlantic margins, with monthly mean significant wave heights changing by up to a factor of two from one year to the next. The most obvious candidate as a source for this variability is the North Atlantic Oscillation (Hurrell, 1995), which has a widespread effect on many facets of climate, particularly in the months of December to March. We use gridded mean significant wave heights from these four calendar months in six consecutive winters, 92/93 -97/98. For each of the 24 months, "anomalies" are calculated by subtracting the mean seasonal cycle. Principal component methods are used to derive a spatial pattern of significant wave height anomalies whose time-dependent amplitudes are maximally correlated to an NAO index (Jones et al., 1997). A model for the anomalies is constructed by using the spatial pattern to calculate coefficients of a linear model relating the monthly anomaly to the monthly NAO index.

Inter-annual variability of wintertime wave climate

(above, spatial pattern of 1st eof; below, principal component (red crosses) and NAO Index (black squares)

The performance of the model is illustrated at a single location (57o-58oN, 8-10oW) on the edge of the Hebridean shelf. This location is typical of the region to the north west of the British Isles where inter-annual variability is greatest. Measured anomalies in excess of 2 metres (above or below the means of about 5 metres in each of the four calendar months) are recorded. These anomalies are well described by the relationship to the NAO. In other regions around the British Isles, the variability is lower and the model is less successful in describing this variability. However, the NAO is apparently a factor in determining wave climate throughout the area with the exception of the East Coast of England and Scotland.

Satellite altimetry provides a consistent coverage of wave climate around the British Isles. Previously, wave climatologies were constructed from measurements at a variety of sites and times (Draper, 1980 and 1991). The new climatology is based on measurements in the 1990s and reflects changes in wave climate since earlier decades (Bacon and Carter, 1991; Alcock and Rickards, 2001). Satellite data indicates that an upward trend in wave heights continued from the late 1980s into the early 1990s (Carter, 1999), but the behaviour during the 1990s was erratic. This behaviour can be explained by the NAO, which shifted towards more positive index values between the early 1960s and late 1990s before dramatically switching to its negative phase in the winter of 95/96. The relationship to the NAO is robust and can be used to hindcast the wave climate in much earlier times (Woolf et al., 2002).

The M/V Aratere Incident

The Maritime New Zealand report of the M/V Aratere incident has just been released. while it was determined that the vessel was constructed to take the large wave pounding.

I want you to note the damage done to this vessel, its crew and passengers.

Imagine a 44 ft sailboat like the Sean Seamour II taking these waves?

New Zealand – report re cargo shift on ferry

Maritime New Zealand issued the report of its investigation into the incident onboard a passenger ferry that experienced heavy rolling and cargo shifts during severe weather. Four passengers and one crewmember were injured and there was significant cargo damage. The report recommends, among other things, further review of weather parameters for Cook Strait crossings and improved training of bridge personnel for ship handling in heavy weather. (Report pdf Aratere 8/23/07).

The MV Aratere is a roll-on roll-off train ferry in service for Interislander in New Zealand. The ferry was built for Tranz Rail, now Toll NZ, in 1998 to replace the aging MV Aratika. The name Aratere means "Quick Path" in the Māori language.

The ships particulars include: Year Built 1998. Builder: Astillero Barreras, Spain. Introduced: 1999. Gross tonnage: 12,300 t. Flag: New Zealand. Passenger capacity: 369. Rail wagon capacity: 60 (425 m). Car capacity: 230. Length: 150m. Breadth: 20.25m. Maximum speed: 19.5kt. Engines: 2x Wartsila type 8L32 diesel engines, each producing 3,680 kW.

We previewed this vessel the Strait Shipping Company "Suilvan" back on June 8, 2007 with a post titled "Another Plane Of View". Speaking about how large waves effect large ships with this video from a shore-base view.





Aratere heavy weather report released
Media release

DATE

STRICTLY EMBARGOED UNTIL NOON 23 AUGUST 2007

Aratere heavy weather report released


Improvements have been made to the way Cook Strait ferries are operated in rough weather following a thorough investigation into the heavy rolling of the Aratere on 3 March 2006.

In releasing Maritime New Zealand’s final report into the incident today (Thursday 23 August), Director Catherine Taylor said while the vessel was capable of withstanding the heavy rolls it encountered, all parties involved accepted that passengers should not have been put in such a position.

“Passenger safety is Maritime New Zealand’s number one priority. This is why we’ve conducted a rigorous investigation, which contains 14 safety recommendations that have already been implemented to improve heavy weather sailing in Cook Strait. This is to ensure that passengers aren’t placed in a situation like this again.”

The report found that during the voyage in rough seas, the Aratere rolled twice to about 50 degrees, with a third roll of approximately 30 degrees occurring when an attempt was made to turn the vessel into the weather.

“Maritime New Zealand considers that although the Aratere itself was sound and was capable of handling the rough seas it encountered, this was still a very serious incident which was understandably very upsetting and uncomfortable for many on board.”

The heavy rolling caused minor injuries to five of the 381 people on board and caused some cargo to break free, damaging rail and vehicular freight. The Aratere arrived safely in Picton several hours later. Other vessels operating in Cook Strait at the same time completed their voyages without incident.

Ms Taylor said MNZ’s final report had considered a wealth of evidence, including eye witness accounts, the advice of overseas experts and technical information from the ship’s voyage data recording instruments. “Based on this evidence, MNZ has concluded that a combination of factors caused the Aratere to roll heavily. While the heavy rolling would have been alarming for those on board, the technical evidence we received appears to conflict with reports that the ship was in serious danger.”

Ms Taylor said the final report also considered the seamanship displayed during the voyage, including the actions of the master and bridge team, as well as issues relating to the cargo lashing system.

“While the report found that the decision to sail was reasonable based on the information available at the time, both Interislander and Maritime New Zealand consider that teamwork on the bridge following the first heavy rolling incident was not functioning as effectively as it should have been.

“Both organisations have been working closely together to address this issue and have implemented a number of safety recommendations.”

Among the actions taken by Interislander is a full review of decision-making relating to rough weather crossings, additional training for ferry masters and crew, improvements to cargo lashing systems and significant investment in overhauling and upgrading the ferries Aratere, Arahura and Kaitaki. Maritime New Zealand has also improved its process for distributing information to ferry companies.

“The purpose of all incident investigations is for the parties involved to learn from them to improve safety, and this is exactly what has happened in this case. Maritime New Zealand’s number one priority is, as always public safety, and we will continue to work with all ferry operators to ensure that the Cook Strait remains a safe place for all to travel.”

Ms Taylor said the report commended the Aratere’s on-board staff for the level of care they displayed towards the passengers during the voyage, and the way in which they kept them informed of the developing situation.

The Transport Accident Investigation Commission also today released its final report into the incident.

ENDS


Safety Recommendations implemented following 3 March 2006 incident

1. It is recommended that Maritime New Zealand:

- Facilitates discussions between the Interislander, Strait Shipping, Wellington Regional Council, Marlborough Regional Council, and the Wellington and Marlborough Harbourmasters through the Cook Strait Ferry Review. These discussions should consider appropriate weather parameters for ferry sailings, including the need for harbourmasters to be consulted on the appropriateness of ferries sailing when wave heights and wind speeds reach certain levels. These discussions have already occurred and are ongoing.

- Continues to conduct ongoing audits of Bridge Resource Management, navigational practice and the lashing system on Aratere and examination of cargo manifests of rail wagons carried, for compliance with the amended Cargo Securing Manual. Ongoing.

- Conducts ongoing audits of all Cook Strait ferries to ensure that trucks are lashed in accordance with the cargo lashing manual. Ongoing.

- Conducts ongoing audits to monitor the implementation of corrective actions proposed by Interislander. Ongoing.

- Reviews its procedures for promulgating safety information, including pertinent IMO circulars. Completed.

2. It is recommended that Interislander:

- Reviews and documents its procedures for downloading VDR information following an accident or incident and ensures that ships’ masters and officers have the knowledge and ability to do so. Completed.

- Ensures that helmspersons on its vessels are adequately trained and practised so that they can competently steer the vessel in all weather conditions. Completed.

- Conducts random, unannounced, command assessments of its masters and officers to check their knowledge of the equipment they use and its limitations, and knowledge of, and compliance with, company procedures. Ongoing.

- Formalises a policy that Masters and, if appropriate, officers and crew, are stood down from duty following a significant accident or incident for recovery, and to ensure their availability for internal and external investigations. Completed.

- Resolves confusion over optimum rudder angles, in particular the operating conditions applicable to high-lift rudders. Completed.

- In conjunction with its ships’ masters, review the use of stabilisers when running down weather in heavy weather conditions, and in particular when there is a risk that the vessel may be subject to surf riding. Completed.

- Require masters and deck officers to undergo initial training in heavy weather ship handling followed by regular refresher training. Completed.

- Extend the simulation modelling being carried out by naval architects into ship/tide/weather interactions in the Cook Strait, to include interaction between the ship and conditions likely to be experienced in the entrance channel to Wellington Harbour and the eastern entrance to Tory Channel in severe southerly weather. Completed.

- Provide MNZ with the results of any internal investigation and follow up action as a matter of course, rather than being required to do so. Ongoing.

Weather Story ...Well here is the rain totals for Chicago from from July through August by Northern Illinois University...

After a major event (we're still awaiting official word from the USGS and hydrologists on what type of event this was, IE, one in a 50 or 100 year flood, etc), people have been asking if that was a record rainfall we had last week.Rockford and Madison, WI have had their wettest Augusts ever, so how are we doing?

To answer that question, let's look at July and August 2007 up until
today.

July 2007: 8.20"

August 2007 (so far): 11.64"


July-August 2007 combined rainfall total: 19.84"

The top 4 wettest Augusts ever:
1. 14.23" -1987
2. 11.64" -2007

3. 11.17" -1900

4. 10.94" -1937


The top wettest July-August combined totals ever:
20.14" -1987 19.84" -2007 17.58" -1996 16.77" -1900

We still have essentially 3 more days to go to add to the totals. There is
a possibility that if we get .30" of rain Tuesday evening into Wednesday, we would tie the wettest July-August combined ever.

Finally, I had two brief periods to go out and take a few pictures of the
flooding here on campus on Friday.

I took these around Barsema Hall,
Gilbert Hall/Music building, Castle Drive, inbetween Faraday and Faraday West, and from my perch here on Davis Hall (the silly flash wouldn't shutoff on those pictures---sorry about that): http://weather.admin.niu.edu/floodof2007/ But still, some good pix in there nonetheless.

Yes, that's an upset beaver
in there on Castle Drive, annoyed that his dam is now somewhere on the Mississippi River. He walked right in front of me, but I didn't have my camera ready at that moment.

Also, Dr. Walker Ashley, a meteorology professor here at NIU, who had more
time, got a considerably better variety and angle of shots: http://thetae.blogspot.com

Thanks to Dave Changnon for the help in acquiring the data, and to the

BACKGROUND AND KEY DEVELOPMENTS

  • On August 21, Hurricane Dean was downgraded from a category five to a category one hurricane on the Saffir- Simpson scale as it crossed Mexico’s Yucatan Peninsula and northern Belize. The storm continued across the Bay of Campeche on August 22, making landfall at 1230 hours eastern standard time near the town of Tecolutla, 40 miles south-southeast of Tuxpan, having strengthened slightly to a category two hurricane. According to the U.S. National Hurricane Center, Dean is expected to weaken as it moves inland.
  • Impact assessments are ongoing in Belize and Mexico, but early reports indicate less damage than originally expected.
  • Beginning on August 17, Hurricane Dean passed through the Eastern Caribbean as a category two storm, strengthening to category four as it moved across Jamaica. The hurricane caused damage in St. Lucia, Dominica, Jamaica, Haiti, Dominican Republic, and Martinique. The most damage reported to date is in Jamaica.
  • In response to the impact of Hurricane Dean in Jamaica, USAID/OFDA has dispatched relief commodities including 420 rolls of plastic sheeting, 6,250 blankets, 5,000 ten-liter water containers, and 2,592 hygiene kits. The commodities arrived in Kingston on August 22. The total value of all items, including transport, is more than $297,000.
  • On August 22, USAID/OFDA provided $100,000 to the Pan American Health Organization (PAHO) to respond to emergency health needs resulting from Hurricane Dean in Jamaica. To date, USAID/OFDA has provided more than $570,000 to support emergency response activities in Jamaica.

USAID/OFDA Assistance to Jamaica: $572,243
Total USAID Humanitarian Assistance to the Caribbean: $572,243

CURRENT SITUATION

    Jamaica

  • On August 21, USAID disaster response specialists joined field assessments led by ODPEM to five severely affected communities. The teams reported extensive damage in the area of Old Harbour Bay in Saint Catherine Parish, where hurricane force winds demolished an estimated 80 percent of the houses and left thousands in need of relief assistance. These initial assessments also noted that Hurricane Dean killed three people, damaged thousands of houses, and left at least 3,500 people in need of food, water, and relief supplies. The USAID assessment team believes that the number of affected will continue to rise as results from other field assessments become available. Field assessments will continue on August 22.
  • According to ODPEM, although Hurricane Dean struck the island on August 19 as a category four hurricane, the storm did less damage to the island’s infrastructure than was initially anticipated. In contrast to previous hurricanes, such as the destructive Hurricane Ivan in 2004, Hurricane Dean moved quickly through Jamaica, resulting in less heavy rainfall and landslides.

    Belize

  • According to USAID's disaster response specialist in Belize, Hurricane Dean destroyed more than 650 homes and displaced more than 1,600 people. However, the storm did not cause any major damage to infrastructure, and Belize’s international airport and seaports have reopened.
  • On August 21, U.S. Embassy staff conducted an aerial assessment utilizing two U.S. military helicopters, to determine the extent of hurricane damage in Belize. The overflight revealed some roof and crop damage, but overall was much less than initially expected.

    Mexico

  • USAID emergency staff are conducting preliminary damage and needs assessments in the affected areas of Mexico, but reports to date indicate that because of excellent disaster preparedness planning and actions taken by the Government of Mexico (GOM), no one died in the Yucatan Peninsula as a result of Hurricane Dean and property damage was less than expected.
  • Cancun International Airport did not sustain significant damages during the hurricane, and the airport is on stand-by to receive flights carrying relief supplies in the event that the areas impacted by Hurricane Dean require assistance. To date, 85 percent of cellular communication is operating and public transportation and water services have resumed normal operations in Cancun, according to the Municipal Office of Public Works.
  • As of August 21, the Chetumal Airport remained closed, and public transportation has not resumed operations.

USG HUMANITARIAN ASSISTANCE

  • USAID/OFDA is monitoring Hurricane Dean’s track and impact from the Latin America and Caribbean (LAC) Regional Office in San Jose, Costa Rica, as well as from Washington, D.C. USAID/OFDA staff are currently in Barbados, Belize, Dominica, the Dominican Republic, Guatemala, Haiti, Honduras, Jamaica, Mexico, and Nicaragua. In total, 22 USAID/OFDA emergency staff are deployed to respond to the impact of Hurricane Dean.
  • Jamaica: On August 20, U.S. Ambassador to Jamaica Brenda LaGrange Johnson declared a disaster due to the damage caused by Hurricane Dean. In response to the impact of the hurricane, USAID/OFDA has dispatched relief commodities to Jamaica. The commodities, which include 420 rolls of plastic sheeting, 6,250 blankets, 5,000 ten-liter water containers, and 2,592 hygiene kits, are scheduled to arrive in Kingston on August 22. The total value of all items including transport is $297,243. USAID/OFDA has also provided $100,000 to support emergency health services through PAHO and $175,000 to ODPEM for emergency relief supplies. A six-member USAID assessment team, which arrived in Jamaica on August 18, continues to conduct assessments and coordinate response efforts with U.N. agencies, Government of Jamaica authorities, non-governmental organization (NGO) partners, donors, and other disaster assessment teams.
  • Mexico: On August 19, in advance of Hurricane Dean, USAID deployed three disaster response specialists to the Yucatan as well as a three-person team to Mexico City to work closely with the USAID mission, U.S. Embassy, and the GOM. The response specialists are currently conducting joint damage assessments with Mexican disaster responders. Two USAID emergency staff are traveling to areas around Vera Cruz to support assessments following Hurricane Dean’s second landfall. However, no U.S. assistance has been requested by the GOM.
  • Since 2000, USAID has provided more than $142 million in response to the devastating effects of hurricanes and tropical storms throughout Central America and the Caribbean.

Weather Story

The Chicago storms of August 23 and 24th brought some very interesting and severe weather to the region. Here is one of the storm captured by Storm Chaser John Farley on August 24, 2007 in Madison County, Illinois

Stormy Chicago

While we were tracking Hurricane Dean in the Gulf of Mexico, we here in Chicagoland had our own interesting weather for the past few days. Thursday August 23, 2007 was the worse.

Matter of fact the entire region from Iowa to Indiana to Illinois to Michigan suffered from severe storms.


NIU DeKalb Campus declared an emergency closure. In a statement the university stated;

"Due to potentially worsening flood conditions on our DeKalb campus, the university has declared an emergency closure and urges those personnel who are not designated as essential to emergency services to leave campus as soon as possible.

Only two bridges in DeKalb are currently passable, and with additional rain forecast, travel throughout the county is likely to grow increasingly difficult as the day goes on.Due to the status of this action as an emergency weather closure, personnel will not need to use leave time.The university*s regional centers in Rockford, Naperville and Hoffman Estates are not affected by this closure and remain open. Please use caution in traveling due to flooding road conditions."


Thursday was some of the worse weather Chicago has seen in years.

I was downtown during the height of the storm and clocked wind gusts at 63 MPH along N. Michigan Avenue, with wind driven rain where most trying to walk N. Michigan Avenue were doing so without much success. To say the least, umbrellas were useless.

Damage in my immediate area was limited to fallen trees around N. Michigan and Lakeshore Drive. Flooding was extensive along Lakeshore with beach access tunnels flooded. Ohio Street beach also flooded.
The lightning show was just fascinating as well as dangerous.

Here are just some of the other damage reports from the region.

310,000 powerless in Chicago area

The Associated Press
A fast-moving storm packing winds over 70 mph turned skies from day to night across a wide swath of the Chicago area Thursday, damaging homes and businesses, splitting trees and bringing planes and trains to a halt.

About 310,000 customers in northern Illinois were without power Thursday night, including 62,000 in Chicago, said ComEd spokesman Tom Stevens, who added that it could take days to restore power for some customers north of the city.

People who ventured out to survey the storm's aftermath dodged felled trees, downed power lines and other debris knocked about by high winds.

Chicago officials said the city's emergency center been called for nearly 1,300 "tree emergencies," which included uprooted and split trees and limbs blocking intersections.

Langford said trees in several areas of the city hit power lines and exploded transformers, setting utility poles on fire.

"This is not a storm that's isolated," said Chicago Fire Department spokesman Larry Langford. "This one hit the entire city north to south."

A roof collapsed at the dock area of an industrial building in the suburbs, injuring 40 people, authorities said. West Chicago Police Department spokesman Mike Uplegger said seven people were sent to hospitals and the rest refused treatment at the scene. None of the injuries was considered life threatening.

A large piece of metal scaffolding at Northwestern Memorial Hospital's Prentice Women's Hospital collapsed during the storm, and two people suffered minor injuries but refused treatment, Langford said. Also, the rear wall of a four-story building under construction on Chicago's North Side collapsed, but no injuries were reported, he said.

Officials warned residents to prepare for flooding, with one to two inches of rain drenching on an already waterlogged area.

"That's what we're worried about right now," said National Weather Service meteorologist Nathan Marsili. "It could turn out to be a pretty bad flooding situation for the area."

Elizabeth Schreiber, who works at a public relations firm in Chicago, was in a cab returning from a work lunch when she looked out the window and noticed a tree had smashed into her 1998 Toyota Camry.

The uprooted tree lay across two other vehicles and her car, completely crushing its roof.

"It looks crazy around here," she said while waiting for help. "It's really bad."

Matt Steinkraus, 29, of St. John, Ind. — in Chicago for his wedding on Saturday — was walking downtown with his fiancee and friends when the storm struck.

"As soon as it hit, we made a break for the nearest bar," he said. "We got drenched ... then we went into the bathroom, wrung out our shirts, ran them under the dryer."

About 500 flights were canceled at O'Hare International Airport Thursday evening and passengers should expect delays of more than 2 1/2 hours, according to Chicago Aviation Commissioner Nuria Fernandez. Delays at Midway Airport averaged 1 1/2 to 2 hours.

Judy Pardonnet, a spokeswoman with Metra commuter rail system, said there were delays throughout the system because of debris on the tracks and malfunctioning signals.

"It's going to be a slow commute home for us," she said.

The National Weather Service would not be able to confirm tornado touchdowns until Friday, meteorologist Gino Izzi said. He said 74 mph wind gusts were recorded in Midlothian and near Wrigley Field.

As the storms rolled through, officials feared flash flooding. Some areas of northern Illinois could see 3-5 inches of rain — of particular concern because the ground is so saturated with water from recent rains, Izzi said.

"If that happens, you could be talking very serious flooding," Izzi said.

In Fox Lake in far-northern Illinois, the Fox River flooded some homes while other residents stacked sandbags to protect their houses, said Ami McEwan, assistant administrator for Lake County.

"Most of them are sandbagging and keeping it at bay," she said.

In downtown Gurnee, just west of Waukegan, workers were stacking sandbags to protect an elementary school from the Des Plaines River, she said. School hadn't yet started for the fall, so no students were affected.

A foot of water stood over roads in the Rochelle area, about 20 miles west of De Kalb, and the Des Plaines River was more than 3 feet above flood stage north of Waukegan, according to the weather service.

An afternoon storm that included high winds uprooted trees and damaged homes and knocked out power across Galesburg, about 40 miles northwest of Peoria, according weather service and local authorities. The storm also blew the windows out of a church in nearby Toulon, and knocked out power lines across Stark County, just north of Peoria.

Trees and limbs were down all over town, but no one was hurt by the fast-moving storm, Galesburg Fire Department Battalion Chief Brad Stevenson said.

"It was such a broad area, and it came up so quick and was gone so quick," he said.

FEMA National Situation Update


State Flooding & Severe Weather Reports

Region V Illinois

Severe storms moved through northeast Illinois (Chicago area) in the afternoon on August 23, 2007, causing power outages, downed trees, and roof damage to several buildings.

One fatality has been confirmed in Knox County due to a falling tree. No other injuries have been reported to the State.

Power outages have been reported in Cook County, Knox, LaSalle and Warren Counties.

At 3:30 pm CDT, August 23, 2007 the Exelon Nuclear Power Plant at Braidwood had one unit manually shut down by the operators due to loss of vacuum. The loss of vacuum was caused by the automatic shut down of 2 circulating water pumps when the pumps experienced fluctuations. This is standard protocol with this type of mechanical failure and the reactor was shut down without incident.

Braidwood Unit 1 is still at power and both reactors at the Braidwood site are stable. This is not a classifiable incident under NRC regulations and poses no danger to the public or the workers at the station. The US NRC has been notified. The IEMA resident inspector is on-site.

The majority of damages reported have been minor.

The State EOC is being staffed, but has not been activated. The State has requested Illinois State Patrol, Illinois Department of Transportation, Illinois Department of Natural Resources, External Affairs and a Legislative Liaison to report to the EOC. There have been no requests for State Assistance. Continue reading...

Again? Chicagoland! UPDATE!

As if we have not had enough rain for the past few days!

UPDATE:
Good news...a line of severe thunderstorms has formed over central Illinois and will keep us from getting the really nasty ones.

Furthermore, the upper disturbance now in southeastern Iowa has taken a
jog south.

We will still see scattered showers and thunderstorms through tonight, but amounts should be a half inch or less, for the most part. That said, the flood warnings continue through 12:15 PM tomorrow for creeeks and streams, but the Kishwaukee River crested around noon at 15.24', the second highest crest ever recorded. The National Weather Service has also dropped their new flash flooding risk to us to slight, and just barely:

http://www.hpc.ncep.noaa.gov/qpf/94ewbg.gif

Rainfall totals so far are at:

http://weather.admin.niu.edu/statement.txt

The NWS is continuing the flood watch in the event we do get a half inch of rain tonight, which would cause the rivers and streams to rise back up a bit.
