1. Rainfall around the southern periphery of Tropical Storm Peter may lead to areas of urban and small stream flooding from late Sunday into Tuesday across Puerto Rico, the Virgin Islands, and the Northern Leeward Islands.

There are no coastal watches or warnings in effect. Interests in the northern Leeward Islands, Virgin Islands, and Puerto Rico should monitor the progress of this system.

RAINFALL: The outer bands south of the Tropical Storm Peter could produce rainfall totals of 1 to 3 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. Please consult products from your local weather office.

At 900 AM AST (1300 UTC), the center of Tropical Storm Peter was located near latitude 17.6 North, longitude 56.0 West. Peter is moving toward the west northwest near 15 mph (24 km/h) and this motion is expected to continue through Wednesday. On the forecast track, Peter is expected to pass well to the north of the northern Leeward Islands on Monday and Tuesday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Some additional strengthening is forecast during the next day or so, followed by a slow weakening trend by late Monday and on Tuesday. Tropical storm force winds extend outward up to 105 miles (170 km) from the center. The estimated minimum central pressure is 1008 mb (29.77 inches).

Satellite imagery as well as data from a Air Force Reserve Hurricane Hunter aircraft indicate that the center of Peter is over 100 n mi west-southwest of its forecast position. Therefore, a special advisory for track is being issued. The forecast track has been adjusted through the first 60 h, resulting in a slight southward adjustment of the track through the first couple of days. The aircraft also measured 925 mb flight-level winds of 56 kt, which supports an initial intensity of 40 kt. No adjustments were made to the intensity forecast. The next full advisory will be issued at 1500 UTC.

Based on the track, intensity, and wind radii forecast, no tropical storm watches or warnings are required for the northern Leeward Islands, Virgin Islands or Puerto Rico. However, interests there should monitor the progress of the system as locally heavy rain is possible on Monday and Tuesday when it is expected to pass to the north of the area.
