Southeast Gulf of Mexico .SYNOPSIS...Strong high pres ridging extending from the western Atlantic across the eastern and central gulf waters will maintain strong SE return flow through early Thu afternoon. The ridge will weaken starting Thu afternoon as it shifts eastward in response to a cold front that enters the NW Gulf early on Thu. The cold front will reach from SE Louisiana to near Tuxpan, Mexico by Thu night, and weaken as it reaches from near Sarasota to the Yucatan Peninsula by Fri night. The front will be preceded by a trough and followed by mainly fresh N to NE winds, except for strong NW winds along portions of the Mexican coast adjacent to the SW Gulf on Fri. A trough will develop over the Yucatan peninsula each evening through Fri and shift westward across the SW Gulf during the overnight hours. .TONIGHT...E winds 15 to 20 kt.

The gradient between it and the front will result in strong NE to E winds over the area through early Tue, then become confined to the far southern waters from the rest of Tue through Wed by which time they will be diminishing as the high pres weakens as it slides eastward. Strong NE winds will pulse near the entrance of the Windward Passage through Fri. Large N to NE swells will impact the waters NE and E of the Bahamas Tue through early on Thu. These swells will propagate into the NE Caribbean passages Wed through Thu. The next cold front should approach the far northwest corner of the area on Fri, and move across the extreme northwest waters on Sat. .TONIGHT...NE to E winds 20 to 25 kt.
