Jamaica is spared the worst of Dean but is certainly lashing out at the island. At this time Dean is speeding away from the island about 20mph. The latest data from the recon plane indicates the pressure is at 926mb and the highest winds found at this time are 143mph at flight level so that would translate to about 120mph at the surface. Of course that is just a sample of what the aircraft can measure. When the National Hurricane Center announce the wind speed for any storm that also take into account satellite images and surface readings and they come up with the maximum winds for a storm. I would expect the winds to be maintained at 145mph for the 11pm advisory.
Due to work I will not be able to post again until tomorrow night. More then...
