Hurricane Dean Discussion – 2007-5

***Dean Makes Landfall as a Category 5 Hurricane***
Valid: 08/21/2007.

At 7:00am CDT –

– The center of Category 3 Hurricane Dean was located inland over the Yucatan Peninsula about 40 miles northwest of Chetumal, Mexico. Movement is towards the west at 17 mph and this motion should continue the next 24 hours and should reach the southern Bay of Campeche late this afternoon. Maximum sustained winds are 125 mph and further weakening is likely while Dean remains overland. Strengthening should occur once Dean emerges into the Bay of Campeche. Minimum surface pressure is 935mb.

– Dean made landfall near Costa Maya around 3:30am CDT with a minimum surface pressure of 906mb and unofficially measured winds near 178kts.

– Dean is the 9th lowest central pressure on record for the Atlantic Basin. It also is the third lowest pressure recorded at landfall. Finally, Dean is the first Category 5 hurricane to make landfall in the Atlantic Basin since Andrew of 1992.

– Dean is not a threat to the U.S. and should make final landfall by Wednesday afternoon.

Discussion:

There is no change to the forecast track or reasoning.

Intensity wise, Dean may remain organized enough to restrengthen to a Category 3 hurricane by final landfall. It won't have much time, but given how organized it was at landfall this morning, anything can happen.
