Cloudiness and thunderstorms associated with a large low pressure system located about 1500 miles east of the Windward Islands continue to show signs of organization.

Environmental conditions are expected to remain conducive for a tropical depression to form
later today or on Wednesday. This system has a high chance (70 percent) of becoming a tropical cyclone during the next 48 hours as it moves westward at 5 to 10 mph.

A vigorous tropical wave is located over the tropical atlantic about 1100 miles east-southeast of the Windward Islands.

Environmental conditions appear favorable for some slow development of this system during the next couple of days.

There is a low chance (20 percent) of this system becoming a tropical cyclone during the next 48 hours as it moves westward or west-northwestward at 15 to 20 mph.

Track of Low Pressure System

Shower and thunderstorm activity in association with a low pressure system near the Windward Islands remains disorganized. However, data from another national science foundation reconnaissance mission into and around this system continue to indicate a well-defined circulation.

Environmental conditions remain conducive for a tropical depression to form during the next couple of days as the system moves slowly west-northwestward. There is a medium chance (50 percent) of this system becoming a tropical cyclone during the next 48 hours.

Hurricane Omar weakens to a tropical storm

Hurricane Omar - October 16th, 2008

Omar has now weakened to a tropical storm. As of 11:00P.M. AST, according to the U.S. National Hurricane Center, it was about 810km (505mi) northeast of the Leeward Islands and 1150km (715mi) southeast of Bermuda. It is moving northeast at approximately 41km/h (25mph). It is expected to continue moving north-northeast over the next few days, while decreasing slightly in forward speed. Its maximum sustained winds have decreased to about 110km/h (70mph), with higher gusts; it should weaken somewhat over the next couple of days. It has tropical storm force winds extending up to 230km (145mi) from its center.

In the main image, the eastern end of the Dominican Republic is mostly visible on the left, with Puerto Rico and the U.S. and British Virgin Islands to its right, partially visible below the clouds. The coast of Venezuela can also be seen in the bottom of the image. Other islands, such as Antigua and Barbuda , are covered by the tail of the storm.

After having strengthened to a Category 3 hurricane early on October 16th, increased wind shear caused Omar to weaken rapidly after passing by the Leeward Islands. Although Omar went over the Leeward Islands at peak intensity, its eyewall remained over water so damage was relatively light. Some flooding was reported and some trees were knocked down, but there were no reports of significant structural damage.

Omar caused wind damage in the southern part of the Windward Islands, including Aruba, Curaçao and Bonaire. While the trade winds usually blow from the east to the west, and all coasts and beaches are on the west side of the islands, on October 14th Omar brought strong west winds with it and caused severe damage at the coasts, a lot of power outages and fallen trees.
