At 1100 AM, the center of Tropical Depression Isaac was located near latitude 14.9 North, longitude 67.3 West. The depression is moving toward the west near 16 mph (26 km/h), and this general motion with some decrease in forward speed is expected over the next couple of days.  A turn to the west-northwest is possible early next week if Isaac survives.  On the forecast track, Isaac will move over the eastern and central Caribbean Sea during the next few days.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Isaac is forecast to gradually weaken over the next few days, and could degenerate into a tropical wave at any time.  A NOAA Hurricane Hunter aircraft is currently en route to investigate the depression.

The estimated minimum central pressure is 1007 mb (29.74 inches).



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 Jamaica. This rainfall may cause life-threatening flash floods.
