HAZARDS AFFECTING LAND
----------------------
RAINFALL: Rainfall around the southern periphery of Tropical Storm
Peter could produce additional rainfall totals of 1 to 4 inches,
with storm total accumulations up to 6 inches, across portions of
the Northern Leeward Islands, including portions of the Virgin
Islands, as well as Puerto Rico and the northern portions of
Hispaniola through Thursday morning. This rainfall may lead to areas
of urban and small stream flooding.
SURF: Swells generated by Peter are affecting the northern Leeward
Islands and Puerto Rico, and will continue spreading westward to
Hispaniola later today and the Bahamas on Wednesday. These swells
could cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
