The tropical storm warning for the U.S. Virgin Islands and Puerto Rico has been discontinued by the National Hurricane Center, as the storm has moved away from the Virgin Islands and was almost past Puerto Rico at 5:00 p.m. Sunday.

According to N.H.C.'s 5:00 p.m. Sunday forecast, the center of Tropical Depression Grace was located near latitude 17.0 North, longitude 67.3 West. The depression is moving toward the west near 15 mph (24 km/h). A generally west-northwestward motion is expected over the next few days.

On the forecast track, Grace will move over Hispaniola on Monday, near or over eastern Cuba on Tuesday, and near or over west-central Cuba on Wednesday.

Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Little change in strength is forecast during the next 48 hours.

The estimated minimum central pressure is 1011 mb (29.86 inches).

Wind: Tropical storm conditions are possible in the Dominican Republic tonight and Monday, and in Haiti on Monday and Monday night.

Rainfall: The system is expected to produce the following rainfall amounts today into Tuesday:

Virgin Islands...3 to 6 inches. This rainfall may produce scattered areas of flash and urban flooding.

Over Puerto Rico...3 to 6 inches with isolated higher amounts. Heavy rainfall could lead to flash, urban and small stream flooding and possible mudslides.

Over Haiti and the Dominican Republic...4 to 8 inches with isolated maximum totals of 15 inches across southern terrain areas. Heavy rainfall could lead to flash and urban flooding and possible mudslides from Monday into Tuesday.

By mid to late week, heavy rainfall from this system could impact portions of Cuba, the Bahamas and Florida.

Surf: Swells generated by Grace will continue to affect portions of the Leeward Islands, the Virgin Islands and Puerto Rico and will reach portions of Hispaniola tonight and Monday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
