At 200 PM AST (1800 UTC), the center of Tropical Storm Don was
located near latitude 11.5 North, longitude 58.7 West. Don is
moving toward the west near 20 mph (31 km/h). This general motion
is expected through Wednesday. On the forecast track, the center of
Don will move across the Windward Islands later today or tonight,
and then move westward across the southeastern Caribbean Sea on
Wednesday.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Little change in strength is forecast before Don moves
through the Windward Islands. The tropical storm is forecast to
degenerate into a trough of low pressure over the southeastern
Caribbean late Wednesday or Wednesday night.

Tropical-storm-force winds extend outward up to 35 miles (55 km)
from the center.

The estimated minimum central pressure is 1011 mb (29.86 inches).
