Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea, and Tropical North Atlantic from 07N to 19N between 55W and 64W and the Southwest North Atlantic including the Bahamas


...GULF OF MEXICO...


...A Very Progressive Winter Pattern continues across the area...

Low pressure of 1012 mb over the eastern Gulf near 27N84W has a weak trailing cold front to near 21N91W. The low will track east-southeast, reaching S Florida this morning while the front sags S and slowly dissipates. Another cold front will move off the Texas coast tonight and weaken by the time it reaches the southeastern Gulf Wed night ahead of a third cold front, that is forecast to move across the Gulf waters Thu night through Sat night. This front is expected to be followed by fresh to strong northerly winds and building seas. North winds may reach frequent gusts to gale force over the far west-central waters on Fri west of 96W and in the SW Gulf.


...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W...

Relatively weak high pressure across the region will maintain rather quiet conditions over the forecast waters allowing for generally gentle to moderate winds across most of the Caribbean Sea. Winds will begin to increase across the south-central Caribbean Thu night through Sat night, with strong to near gale force winds near the coast of Colombia at that time. Winds may possibly reach minimal gale force strength on Fri night and Sat night.


...SW N ATLANTIC INCLUDING THE BAHAMAS...


...A Very Progressive Winter Pattern continues across the region...

A cold front has moved over the far northwest waters along a position from near 31N76W to 30N81W. Fresh to strong winds are ahead and behind the front along with building seas east of the front. The front will reach from near 31N70W to southeastern Florida this morning, and from 31N60W to the central Bahamas by tonight. A low pressure system will move across northern Florida Wed, emerge off the coast Wed night, then track east across the area through Thu night. High pressure ridging will build across the area in the wake of this system Fri and Fri night. Another low pressure system is forecast to track northeastward along southeastern and mid-Atlantic U.S. coast from Fri through Sat night, with a trailing cold front that will sweep across the western and central forecast waters. Fresh to strong winds are expected on either side of this front to the north and northeast of the Bahamas, with southerly winds possibly reaching to near or minimal gale force near 31N and east of 70W on Sat and Sat night. Waveheights are expected to build to a peak of around 11 ft with these winds.
