DISCUSSION AND OUTLOOK
At 500 AM AST (0900 UTC), the center of Tropical Storm Dorian was
located near latitude 16.8 North, longitude 63.9 West. Dorian is
moving toward the northwest near 13 mph (20 km/h), and this general
motion is expected to continue during the next few days. On the
forecast track, the center of Dorian will pass over or near the U.S.
and British Virgin Islands and Puerto Rico later today. Dorian is
then forecast to move to the east of the Turks and Caicos and the
southeastern Bahamas on Thursday, and near or to the east of
the central and northwestern Bahamas on Friday and Saturday.
Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Some strengthening is expected today, and Dorian is forecast to be
near hurricane strength when it approaches the Virgin Islands
and Puerto Rico. Although weakening is possible after Dorian moves
across Puerto Rico and the Virgin Islands, the storm is forecast to
strengthen late this week and this weekend while passing near or to
the east of the Turks and Caicos and the Bahamas.
Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.
The estimated minimum central pressure is 1003 mb (29.62 inches).
