***Dean a Catastrophic Category 5 Hurricane***
***This is a Life Threatening Situation***
Valid: 08/20/2007.

At 7:35pm CDT –

– The National Hurricane Center has upgraded Dean to the highest hurricane classification, Category 5. Dean has measured, sustained winds of 160mph with higher gusts. Minimum surface pressure is 914mb.

At 7:00pm CDT –

– The center of Hurricane Dean was located 210 miles east of Chetumal Mexico. Movement is toward the west at 20mph and this motion is expected to continue during the next 24 hours.

– Dean is not a threat to the U.S.

– First landfall is expected around 10:00am CDT near Chetumal Mexico. Second landfall is expected along the central Mexican coast Wednesday morning.

– Hurricane force winds extend outward to 60 miles from the center and tropical storm force winds to 175 miles.


Little to say about the forecast track. Despite my thinking Dean would hit Corpus that will not happen. Dean is being stirred almost due west by a strong and deep layer ridge to its north. This will stir Dean across the Yucatan into the Bay of Campeche. Dean will likely regain some strength after it moves back over water and may become a major hurricane before final landfall on Wednesday.

Fluctuations in intensity are likely with Dean, as is common with hurricanes this strong. However, there are no reasons why Dean won't make first landfall as a Category 5 hurricane.
