Southeast Gulf of America

SYNOPSIS
Gentle to moderate SE winds and slight to moderate seas will prevail over much of the Gulf of America through Tue. Fresh to strong SE to S winds will develop Tue night across much of the basin west of 85W, as the pressure gradient tightens between building high pressure in the western Atlantic and strengthening low pressure in the central United States. East of 85W, moderate SE winds Tue night will strengthen to fresh to locally strong speeds Wed into Thu, including through the Florida Straits.

Within 200 nm east of the coast of Florida

SYNOPSIS
Fresh S winds are expected to develop this afternoon north of 29N well off the coast of Florida to 70W, as the pressure gradient strengthens between high pressure in the central Atlantic and low pressure moving through the eastern United States. A cold front associated with the low pressure system is slated to push offshore of the southeastern U.S. on Tue, and winds behind the front will turn to the W and weaken in its wake. Looking ahead, high pressure is slated to develop over the western Atlantic by midweek. A tightening pressure gradient between the high and the Colombian low will support fresh to strong E to SE winds and rough seas across the waters south of 27N.
