Puerto Rico - January 3rd, 2012

This orthorectified wide-swath ASAR image shows the Virgin Islands, the eastern island group of the Leeward Islands. The Leeward Islands are the northern part of the Lesser Antilles, which form the border between the Caribbean Sea and the Atlantic Ocean. Politically, the eastern islands form the British Virgin Islands and the western ones form the United States Virgin Islands.

Here, Puerto Rico is partially visible at the left edge. The island southeast of Puerto Rico is Vieques, an island-municipality of Puerto Rico. The island near the bottom edge is Saint Croix, one of the U.S. Virgin Islands. The remaining islands above are divided among the British and U.S. Virgin Islands.

Most of the islands are volcanic in origin and have a hilly, rugged terrain. Anegada, one of the British Virgin Islands, is geologically distinct from the rest of the group and is a flat island composed of limestone and coral. Saint Croix, the largest of the US Virgin Islands, also has a flatter terrain.

Track of Erika

At 11:00 PM AST (0300 UTC), the center of the remnant low associated with former Tropical Depression Erika was located about 115 miles (185 km) south-southeast of San Juan, Puerto Rico and about 220 miles (360 km) southeast of Punta Cana in the Dominican Republic. Here, the coast of Venezuela can be seen south of the low.

The low is moving toward the west near 7 mph (11 km/hr). A gradual turn to the west-northwest and northwest is expected on Friday.

Maximum sustained winds are near 30 mph (45 km/hr) with higher gusts in a few squalls. The low is forecast to dissipate in a day or so. Estimated minimum central pressure is 1009 mb (29.80 inches).

The remnants of Erika are expected to produce total rainfall accumulations of 2 to 4 inches over the central and northern Lesser Antilles, Puerto Rico, and the US and British Virgin Islands, with isolated maximum amounts of 6 inches possible.
