Based on data from a Air Force Reserve Hurricane Hunter aircraft, 
maximum sustained winds remain near 45 mph (75 km/h) with higher

slight weakening is expected tonight into Monday.

Tropical-storm-force winds extend outward up to 115 miles (185 km), 
primarily northeast of the center.

The estimated minimum central pressure based on the aircraft data 
is 1007 mb (29.74 inches).

RAINFALL:  The outer bands south of the tropical storm 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 late today through
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 tonight and Monday.  These
swells could cause life-threatening surf and rip current conditions.
