DISCUSSION AND OUTLOOK

At 500 AM AST (0900 UTC), the center of Tropical Storm Kirk was
located near latitude 13.2 North, longitude 62.5 West. Kirk is
moving toward the west near 12 mph (19 km/h), and this motion is
expected to continue during the next day or two. On the forecast
track, Kirk's center, or its remnants, will move across the eastern
and central Caribbean Sea over the next 2 or 3 days.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Kirk is forecast to weaken to a tropical depression later today or
Saturday, and then degenerate into a trough of low pressure.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
to the north and east of the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are still occurring over portions
of the warning area and should continue to spread across the
remainder of the warning area today.  Tropical storm conditions
are possible within the watch area during the next several hours.
Locally higher winds are likely 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 today and Saturday.
