4:15 p.m. update: A Hurricane Hunter aircraft has continued to investigate the low pressure system located about 500 miles east of the Windward Islands.
Observations from the aircraft indicate that this system is producing winds of up to 40 to 45 mph in the northern portion of the circulation.
Showers and thunderstorms could redevelop over the low tonight or Friday, which could result in tropical cyclone formation.
Regardless of development, winds of gale force are likely to spread across portions of the Lesser Antilles beginning early Friday.
Interests in the Lesser Antilles should continue to monitor the progress of this disturbance as it moves west-northwestward near 20 mph, and watches or warnings may be required for some of these islands later tonight or Friday.
* Formation chance through 48 hours…high…70 percent.
* Formation chance through 5 days…high…70 percent.
