is expected to pass well to the north of the northern Leeward

Islands on Monday and Tuesday.

Some additional strengthening is forecast during the next day or

so, followed by a slow weakening trend by late Monday and on

Tuesday.

from the center, mainly to the northeast and southeast of the

center.

The estimated minimum central pressure is 1005 mb (29.68 inches).

HAZARDS AFFECTING LAND

----------------------

RAINFALL: The outer bands south of the Tropical Storm Peter could

produce rainfall totals of 1 to 2 inches across portions of the

Northern Leeward Islands, including the Virgin Islands, as well as

Puerto Rico late Sunday into Tuesday. This rainfall may lead to

areas of urban and small stream flooding.

SURF: Swells generated by Tropical Storm Peter are expected to

reach the northern Leeward Islands Sunday night and Monday. These

swells could cause life-threatening surf and rip current conditions.
