Track of TS 12L

As of 11:00 AM AST (1500 UTC) on September 3rd, the center of, Tropical Storm Leslie (12L)  was located near latitude 24.4 north, longitude 63.1 west.

Leslie is moving toward the north-northwest near 8 mph (13 km/h). A turn toward the north and a slower forward speed is expected over the next 48 hours. Maximum sustained winds remain near 60 mph (95 km/h) with higher gusts. Little change in strength is forecast during the next couple of days. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. Estimated minimum central pressure is 998 mb (29.47 inches).

Hazards affecting land include surf: swells generated by Leslie could affect portions of the Leeward Islands, Puerto Rico and the Virgin Islands for another day or so. Swells could also affect Bermuda and the U.S. east coast from central Florida northward for the next several days. These swells could cause life-threatening surf and rip current conditions.

At 11:00 AM AST (1500 UTC) the center of Tropical Storm Maria (14L) was located near latitude 20.7 north, longitude 67.3 west.

Maria is moving toward the west near 2 mph (4 km/h). A faster motion toward the west-northwest is expected later today, followed by a turn toward the northwest and a further increase in forward speed by early Tuesday.

Maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts. Little change in strength is forecast during the next 48 hours. Tropical storm force winds extend outward up to 200 miles (325 km) mainly to the north and east of the center. A sustained wind of 40 mph (65 km/h) and a peak gust of 49 mph (79 km/h) were recently reported. Estimated minimum central pressure is 1006 mb (29.71 inches).

Hazards affecting land include rainfall and wind. Maria is expected to produce total rain accumulations of 2 to 4 inches, with isolated maximum amounts of 6 inches over the Virgin Islands, Puerto Rico, and portions of the northern Leeward Islands through Tuesday. Wind gusts to tropical storm force are possible, especially over higher terrain in the Virgin Islands, Puerto Rico, and the extreme northern Leeward islands today.

Puerto Rico - December 12th, 2008

Puerto Rico is a self-governing unincorporated territory of the United States located in the northeastern Caribbean, east of the Dominican Republic and west of the Virgin Islands.

It is composed of an archipelago that includes the main island of Puerto Rico and a number of smaller islands and keys, the largest of which are Vieques, Culebra, and Mona (Amoná).

Puerto Rico has an area of 5,325 square miles (13,790 km2). The maximum length from east to west is 110 miles (180 km), and the maximum width from north to south is 40 miles (64 km).

The main island is mostly mountainous with large coastal areas in the north and south. The main mountain range is called “La Cordillera Central” (The Central Range), visible in the center of the island. An algal bloom can be seen off the northeastern coast.

Puerto Rico has 17 lakes, all man-made, and more than 50 rivers, most originating in the Cordillera Central. Rivers in the northern region of the island are typically longer and of higher water flow rates than those of the south, since the south receives less rain than the central and northern regions.

Hurricane Omar - October 15th, 2008

Hurricane Omar strenghtened into a Category 3 storm the evening of October 15th. According to the U.S. National Hurricane Center, as of 3:00A.M.

In the main image, we can see the eastern tips of Cuba and Jamaica, as well as the Turks and Caicos islands, and parts of Haiti and the Dominican Republic as Omar moves northeast. Those islands are partially obscured by clouds due to the great amounts of precipitation still affecting the entire area. Puerto Rico, the U.S. and British Virgin Islands, Anquilla, the Netherlands Antilles and the French West Indies, on the other hand, are completely obscured by the storm.

Omar’s maximum sustained winds are 205km/h (125mph), with higher gusts. It has hurricane-force winds extending outwards 55km (35mi) from its center, and tropical storm-force winds extending 185km (115mi) from the center.

A hurricane warning is currently in effect for Puerto Rico, the U.S. and British Virgin Islands, Anquilla, the Netherlands Antilles and the French West Indies. A hurricane watch has been issued for St. Kitts and Nevis, and a tropical storm warning is in place for Montserrat, Antigua and Barbuda.

Puerto Rico, the Virgin Islands and the northern Leeward Islands could receive 125-250mm (5-10in) of rain, with a maximum amount of 500mm (20in) in some areas. Storm surges could also reach 0.6-1.8m (2-6ft).

It is moving northeast at 9km/h (6mph) with maximum sustained winds of 120km/h (75mph) and stronger gusts. Hurricane-force winds extend up to 30km (15mi) from Omar’s center, and tropical storm-force winds reach out up to 150km (90mi) from its center. It has a minimum central pressure of 984 millibars.

In the image we can see Hurricane Omar, to the right, as well as Tropical Depression 16, to the left.

Omar is currently a Category One hurricane, though it is expected to strengthen over the next 24 hours. A hurricane warning has been issued for the U.S. and British Virgin Islands, St. Martin, Saba, St. Eustatius, St. Barthelemy, Anguilla, St. Kitts, Nevis, Vieques and Culebra, while a tropical storm warning has been issued for Antigua, Barbuda and Montserrat.

The Netherlands Antilles and northern Venezuela could experience rainfall of 100 to 200 mm (4 to 8in), with up to 300 mm (12in) possible in isolated areas of the Netherlands Antilles. Puerto Rico and the northern Leeward Islands could receive 125 to 250mm (5 to 10in), with isolated amounts of up to 500mm (20in).
