The most intense Atlantic hurricane of the season, Hurricane Dean, is making its way toward the United States and Mexico. At this writing it is an extremely dangerous category 4 storm packing winds of 150 mph and bearing down on the island of Jamaica. Forecasters expect Dean to intensify into a deadly category 5 hurricane, following a path much like Hurricane Gilbert, a storm that left 45 dead in Jamaica in 1988.
