DISCUSSION AND OUTLOOK

At 1100 PM AST (0300 UTC), the center of Tropical Storm Isaac was
located near latitude 15.4 North, longitude 69.5 West. Isaac is
moving toward the west near 15 mph (24 km/h) and this general
motion with a slight decrease in forward speed is expected over the
next couple of days. A turn toward the west-northwest or northwest
is possible by the end of the weekend, if Isaac has not degenerated
into a trough of low pressure by then.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. The maximum winds are not expected to change very much
during the next several days.

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).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Isaac is expected to produce additional rainfall of 2 to
3 inches with isolated maximum totals of up to 5 inches across
southeast Puerto Rico. Rainfall totals of 1 to 2 inches with
maximum amounts of 3 inches are possible across the remainder of
Puerto Rico, the Virgin Islands, the Leeward Islands and the
northern Windward Islands. Rainfall totals of 2 to 3 inches with
isolated maximum amounts of 4 inches are possible across the south-
central portion of the Dominican Republic, southwest Haiti and most
of Jamaica except for the eastern portion of Jamaica where rainfall
totals of 2 to 4 inches and maximum amounts of 6 inches are
possible. This rainfall may cause life-threatening flash floods.
