Puerto Rico - December 23rd, 2011

This orthorectified wide-swath ASAR image shows the topography of the island of Puerto Rico. The maximum width of the island from north to south is 65 km (40 mi) and the maximum length of the island from east to west is 180 km (110 mi).

Visible as a white area along the north-eastern coast is San Juan, the capital and most populous municipality in Puerto Rico. It lies south of the Atlantic Ocean; north of Caguas and Trujillo Alto; east of and Guaynabo; and west of Carolina. The city occupies an area of 76.93 square miles (199.2 km2), of which, 29.11 square miles (75.4 km2) (37.83%) is water.

Puerto Rico is mostly mountainous with large coastal areas in the north and south. The main mountain range is called “La Cordillera Central” (The Central Range). The highest elevation in Puerto Rico, Cerro de Punta 1,339 meters (4,393 ft),[117] is located in this range. Another important peak is El Yunque, one of the highest in the Sierra de Luquillo at the El Yunque National Forest, with an elevation of 1,065 m (3,494 ft).

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 TS 12L

The center of Tropical Storm Katia (12L) is located near latitude 19.9 north, longitude 56.8 west. Katia is moving toward the west-northwest near 10 mph (17 km/h) and this general motion is expected to continue through Monday.

Maximum sustained winds have decreased to near 70 mph (110 km/h) with higher gusts. Fluctuations in intensity are possible over the next day or so, and Katia could re-strengthen back to a hurricane at any time.

Tropical storm force winds extend outward up to 140 miles (220 km) from the center. Estimated minimum central pressure is 993 mb (29.32 inches).

Hazards affecting land are mainly related to high surf. Swells generated by Katia are affecting the Lesser Antilles and could begin to affect Bermuda by tonight or Sunday. These swells are likely to cause life-threatening surf and rip current conditions.

Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Katia is a category one hurricane on the Saffir-Simpson scale. Some strengthening is forecast during the next 48 hours, and Katia could become a major hurricane by the weekend.

Hurricane force winds extend outward up to 25 miles (35 km) from the center, and tropical storm force winds extend outward up to 125 miles (205 km). Estimated minimum central pressure is 987 mb (29.15 inches).
