DISCUSSION AND OUTLOOK
———————-
At 800 PM AST (0000 UTC), the center of Tropical Storm Kirk was
located by an Air Force Reserve Hurricane Hunter aircraft just east
of St. Lucia near latitude 13.9 North, longitude 60.7 West. Kirk is
moving toward the west-northwest near 14 mph (22 km/h). A west-
northwestward to westward motion is expected over the next couple of
days. On the forecast track, the center of Kirk will move across
the Lesser Antilles within the Tropical Storm Warning area during
the next several hours.
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Little change in strength is expected while the center of
Kirk moves through the Lesser Antilles. Gradual weakening is
anticipated during the next couple of days while the system moves
over the eastern Caribbean Sea. Kirk is forecast to become a
tropical depression Friday night, and degenerate into a trough of
low pressure by Sunday.
Tropical-storm-force winds extend outward up to 140 miles (220 km)
primarily to the east of the center.
The minimum central pressure based on data from the aircraft is 1002
mb (29.59 inches).
HAZARDS AFFECTING LAND
———————-
WIND: Tropical storm conditions are expected to begin in portions
of the warning area during the next few hours. Tropical storm
conditions are possible within the watch area overnight. Locally
higher winds are possible atop and on the windward sides of hills
and mountains.
RAINFALL: Kirk is expected to produce total rainfall of 4 to 6
inches across the northern Windward and southern Leeward Islands
with isolated maximum totals up to 10 inches across Martinique and
Dominica. These rains may produce life-threatening flash floods and
mudslides. Across Saint Croix and eastern Puerto Rico, Kirk is
expected to bring 2 to 4 inches with isolated maximum totals of 6
inches by Friday and Saturday.
