Well one good thing, between the 8PM Eastern update for Saturday and the 11PM Eastern Update, Dean's projected path jogged south so the eye will pass to the south of Jamaica. Bad news it means Jamaica will get more surge battering its coast as the rain fails amidst the 145MPH winds.
The eye of Dean will skirt to the south of the Caymans by about 30 miles at 8AM Eastern Monday with 150MPH winds in that eye. Still expect the Caymans to get deluged and whipped by the wind.
Landfall in the Yucatan Peninsula is now predicted for after 5AM Eastern on Tuesday with winds possibly at 160MPH. Bad news is Dean continues to speed along. At one time it was traveling at 23MPH, right now it is traveling at 18MPH. If it continues at this speed when it strikes the Yucatan, then Dean just might still be a Category 5 storm at landfall. Earlier models suggested winds of 145MPH at landfall. The entire coast of the Yucatan facing Dean is now under a Hurricane Watch as the predicted spot for landfall has shifted south from the tip to the center of the coast. People in the Yucatan, time to get away from the coast.
Looking towards Wednesday and landfall in Mexico. Brownsville, TX is now the northern most point of the strike cone. And like landfall in Yucatan has shifted south, so to has it shifted for the Mexican coast to being about 200 miles south of Brownsville. Eye landfall is expected to 8PM Eastern on Wednesday with winds of 115MPH.
