Southeast Gulf of America

SYNOPSIS
Weak high pressure will persist over the northeast Gulf through late Fri. A trough over the Bay of Campeche will support moderate to fresh winds off the northern and western coasts of the Yucatan Peninsula, mainly at night, through early next week. The next cold front will move into the northern Gulf early Sat morning, reach the southeast Gulf by Sun morning, and move southeast of the basin late on Sun. Fresh to strong NE to E winds and rough seas are expected in the wake of the front over the eastern Gulf Sat night through early Mon. The pressure gradient will remain strong enough to sustain fresh to strong east winds across the southeast Gulf and the Straits of Florida through the middle of the next week.
