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.
