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).

On Monday, October 13th, an area of low pressure that had formed in the Caribbean was upgraded to a tropical depression. According to the U.S. National Hurricane Center, it could become a tropical storm by Tuesday evening since wind shear will be weakening and the water temperatures are very warm; a tropical storm watch is in effect for Puerto Rico, the U.S. and British Virgin Islands, and the extreme eastern part of the Dominican Republic.

As of Tuesday morning, the center of Tropical Depression 15 was located about 565km (350mi) southwest of San Juan, Puerto Rico and about 225km (140mi) north of Curacao. It is expected to change position very little through Tuesday, as it is moving southeast at only 4km/h (2mph), with maximum sustained winds of about 55km/h (35mph) and higher gusts.

It is currently causing heavy rainfall over the Netherlands Antilles, possibly leading to dangerous flash floods: 4 to 8 inches of total rainfall are expected, though as much as 12 inches are possible. These rains will spread over a wide area, from parts of the Dominican Republic to Puerto Rico to the Virgin Islands.
