Hurricane Dean was measured a Category 5 storm before landfall in Mexico. As Chris Mooney reports, it is one of ten most intense Atlantic hurricanes ever measured.
Dean was officially the most powerful hurricane that we've seen globally so far in 2007, and was by far the strongest at landfall. It was also the first Category 5 Atlantic hurricane seen in the since the record-setting Hurricane Wilma of October 2005. In fact, Dean set some records of its own. Its pressure was the ninth lowest ever measured in the Atlantic, and the third lowest at landfall. Indeed, there hasn't been a full Category 5 landfall in our part of the world since 1992's Hurricane Andrew. Dean was in all respects a terrifying storm, and we can only hope that the damage will somehow be less than expected as it tears across the peninsula and then, after crossing the Bay of Campeche, moves on to a presumed second Mexican landfall.
