Tropical Storm Don Moving Across Windward Islands Wind & Rain
Tropical Storm Don Moving Across Windward Islands
Satellite loops & surface observations show that the western side of Tropical Storm Don is moving across the Windward Islands this evening. Don weakened somewhat this morning but some of the thunderstorms seem to be coming back during the afternoon. Looking at the water vapor loop you can see that Tropical Storm Don remains surrounded by drier air to the north and to the east and to the west. This is not an ideal environment for maintaining tropical storms strength. Westerly winds aloft in the Eastern Caribbean remain problematic and this could wind up shearing Tropical Storm Don apart as it continues toward the west.
There has been no change in the afternoon run of hurricane models. Upper air winds continue to favor a westward track across the Southern Caribbean if it survives.
