Shower and thunderstorm activity has become better organized in association with the remnant low of Tropical Storm Gaston (09L), located about 700 miles east of the Leeward Islands.

Environmental conditions appear conducive for tropical cyclone formation, and the low could redevelop into a tropical depression at any time today as it moves westward near 15 mph.

There is a high chance (80 percent) of this system becoming a tropical cyclone again during the next 48 hours.

Interests in the leeward islands should monitor the progress of this system.  Warnings will likely be required for some of these islands if advisories are re-initiated.

Another tropical wave emerged off Africa near the end of August. Taking advantage of favorable conditions, it developed into a tropical depression on September 1. It intensified later that day to become Tropical Storm Gaston, the seventh named storm of the season and the fourth tropical storm to form in the last eleven days.

As of 5 p.m. AST (2100 UTC) on September 1st, the center of Tropical Storm Gaston was located near 12.9°N 37.0°W, about 895 miles (1440 km) west-southwest of the Cape Verde islands and about 1635 miles (2635 km) east of the Lesser Antilles.

Maximum sustained winds are estimated at 40 mph (65 km/h), with higher gusts. The minimum central pressure is estimated to be 1005 mbar (hPa, 29.68 inHg) and the storm is moving west at 15 mph (24 km/h).
