For the North Atlantic Caribbean Sea and the Gulf of Mexico the National Hurricane Center is issuing advisories on major Hurricane Irene located about 55 miles southeast of Acklins Island in the Bahamas.
1. A low pressure system located about 1150 miles west-northwest of the Cape Verde islands is producing limited cloudiness and shower activity. Although the low is moving west-northwestward at about 15 mph toward warmer waters upper-level winds are currently unfavorable for significant development. This system has a low chance...near 0%...of becoming a tropical cyclone during the
next 48 hours.
2. Showers and thunderstorms continue to show signs of organization in association with an area of low pressure located about 100 miles south of the Cape Verde islands. Environmental conditions appear generally favorable for slow development of this low during the next several days. This system has a medium chance 50% of becoming a tropical cyclone during the next 48 hours as it moves Westward at 10 to 15 mph.
Elsewhere tropical cyclone formation is not expected during the next 48 hours.
