According to Hurricaneville "The storm became a hurricane as of the 5:00 AM EDT Advisory on Thursday morning. With its latest intensification, Dean became the tenth most powerful storm ever in the Atlantic ahead of Hurricane Janet (1955) and Hurricane Isabel (2003), and right behind Hurricane Ivan (2004). It is also the third strongest hurricane to make landfall in North America behind Hurricane Gilbert and the Labor Day Hurricane of 1935. The forecast track has the storm continuing across the Yucatan over the next days, and possibly emerging into the Bay of Campeche region of the Gulf of Mexico later on Tuesday and going into Wednesday as a Category Two Hurricane with 100 mph winds. Forecasted rainfall amounts for the affected areas are expected to range at least between 5 to 10 inches with some locales getting up to 20 inches over Southern and Central Mexico as well as Guatemala. On top of that, storm surge levels could go as high as 6 to 8 feet to the north of the potential landfall point within the Hurricane Warning area."
