Southeast Gulf of America

SYNOPSIS
The gradient related to high pressure ridging over the eastern U.S. that stretches southwestward to the southeastern U.S. is sustaining fresh to strong northeast to east winds and moderate to rough seas over the NE Gulf. These conditions will spread westward over the remainder of the northern Gulf waters through late Thu night before improving Fri into Sat, leading to moderate or weaker winds and slight to moderate seas during the weekend. Meanwhile, a rather broad mid to upper-level trough will move toward Florida from the western Atlantic Thu through Fri as it transitions to low pressure. This feature will lead to increasing shower and thunderstorm activity over the eastern and central Gulf waters.

TONIGHT
NE to E winds 10 to 15 kt. Seas 4 to 6 ft. Winds and seas higher in and near scattered showers and thunderstorms.

THU
E winds 10 to 15 kt. Seas 4 to 6 ft. Scattered showers and thunderstorms.

Within 200 nm east of the coast of Florida

SYNOPSIS
A tight pressure gradient between high pressure over the southeastern U.S. and a stationary front that extends from just east of Bermuda to the NW Bahamas will maintain mostly fresh northeast winds and moderate seas W of the front through Thu. Conditions will improve late Thu into Fri as high pressure becomes the dominate feature across the basin into the weekend. Meanwhile, a broad mid to upper-level trough located just east of the southeastern Bahamas in combination with a very moist and unstable environment will continue to support scattered to numerous showers and thunderstorms over most of the forecast waters through the next few days as the trough gradually transitions to low pressure that will be moving in a west to northwest direction.
