DISCUSSION AND OUTLOOK
At 500 AM AST (0900 UTC), the center of Tropical Storm Dorian was
located near latitude 11.9 North, longitude 56.4 West. Dorian is
moving toward the west near 14 mph (22 km/h). A turn toward the
west-northwest is expected later today, with this motion continuing
through Tuesday night. On the forecast track, the center of Dorian
is expected to be near the Windward Islands late today and tonight
and move into the eastern Caribbean Sea on Tuesday.
Maximum sustained winds have increased to near 60 mph (95 km/h) with
higher gusts. Slow strengthening is forecast during the next few
days, and Dorian could be near hurricane strength on Tuesday and
and Wednesday while it is over the eastern Caribbean Sea.
Dorian is a small tropical cyclone. Tropical-storm-force winds
extend outward up to 45 miles (75 km) from the center.
The estimated minimum central pressure is 1002 mb (29.59 inches).
