Track of TS 18L

Hurricane Sandy (18L) has developed from a tropical wave that was moving westward through the eastern Caribbean Sea on October 19.

On October 20, the system became better organized, although it weakened on October 21. However, by October 22, it became organized enough to earn the designation Tropical Depression Eighteen and was soon upgraded to Tropical Storm Sandy. The main image shows the storm as it was organizing.

The system has since been upgraded to hurricane status. As of 8 p.m. EDT October 25 (0000 UTC October 26), Hurricane Sandy is located within 20 nautical miles of 24.8°N 75.8°W, about 35 mi (55 km) southeast of Eleuthera; about 105 mi (170 km) east of Nassau, Bahamas.

Maximum sustained winds are 85 knots (100 mph, 160 km/h), with stronger gusts. Minimum central pressure is 965 mbar (hPa; 28.50 InHg), and the system is moving north-northwest at 15 kt (17 mph, 27 km/h). Hurricane force winds extend up to 35 miles (55 km) from the center of Sandy, and tropical storm force winds up to 205 miles (330 km) from the center.

Track of Irene

Hurricane Irene (09L) was a large and powerful Atlantic hurricane that left extensive flood and wind damage along its path through the Caribbean, the United States East Coast and as far north as Atlantic Canada.

Irene tracked just north of Hispaniola as an intensifying Category 1 hurricane, skirting the coast with heavy precipitation and strong winds that killed several people.

After crossing the Turks and Caicos Islands, the hurricane quickly strengthened into a Category 3 major hurricane while passing through The Bahamas, leaving behind a trail of extensive structural damage in its wake.

Curving toward the north, Irene skirted past Florida with its outer bands producing tropical-storm-force winds. It made landfall over Eastern North Carolina’s Outer Banks on the morning of August 27 and moved along southeastern Virginia affecting the Hampton Roads region.

After briefly reemerging over water, Irene made second US landfall near Little Egg Inlet in New Jersey during the morning of August 28, becoming the first hurricane to make landfall in the state since 1903. Irene was downgraded to a tropical storm as it made its third U.S. landfall in the Coney Island area of Brooklyn, New York, at approximately 9:00 a.m on August 28.

The most extensive damage within the United States occurred in the Catskill Mountains of New York State and in Vermont, which suffered disastrous flash floods. Throughout its path, Irene caused widespread destruction and at least 44 deaths; monetary losses to the Caribbean could be as high as US$3.1 billion according to preliminary estimates. Early damage estimates in the US are about $7 billion.

Dominican Republic and Haiti - December 19th, 2009

The border between Haiti (west) and the Dominican Republic (east) runs vertically between the two lakes visible in the bottom left corner: Étang Saumâtre (left) and Lake Enriquillo (right).

Lake Enriquillo is located in the Hispaniolan rift valley, which reaches from Port-au-Prince Bay in Haiti to near Neiba Bay in the Dominican Republic. The lake is 9 to 12 miles (15 to 20 km) wide, and covers an area of 102 square miles (265 km²). It is also the lowest point in the Caribbean, falling 129 feet (39 m) below sea level.

Étang Saumâtre (also known as Lake Azuei) is also located in the Hispaniolan rift valley. It Haiti’s largest lake, with an area of around 170 km² (65 square miles). It is some 29 km (18 miles) long and up to 9.7km (6 miles) wide.
