DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Tropical Storm Peter was
located near latitude 20.0 North, longitude 61.8 West. Peter is
moving toward the west-northwest near 14 mph (22 km/h). This general
motion is expected to continue during the next day or so, followed
by a turn to the northwest with a decrease in forward speed on
Wednesday, and then a turn to the north by Wednesday night. On the
forecast track, the center of Peter will pass north of the northern
Leeward Islands and Puerto Rico through Tuesday.
Maximum sustained winds remain near 50 mph (85 km/h) with higher
gusts. Slow weakening is forecast during the next few days.
Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center.
The estimated minimum central pressure is 1007 mb (29.74 inches).
HAZARDS AFFECTING LAND
----------------------
RAINFALL: Rainfall around the southern periphery of Tropical Storm
Peter could produce rainfall totals of 1 to 3 inches, with locally
higher amounts possible across portions of the Northern Leeward
Islands, including the Virgin Islands, as well as Puerto Rico and
the northern portions of Hispaniola through Tuesday. This rainfall
may lead to areas of urban and small stream flooding.
SURF: Swells generated by Peter are expected to affect the northern
Leeward Islands early this week, and then reach the Bahamas by
midweek. These swells could cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.
