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...

Weak ridging extends across the northern Gulf waters this morning. Recent scatterometer data and buoys observations show light to gentle E to SE winds over the northern Gulf, and mostly moderate E winds over the southern Gulf. Winds are pulsing to 20 kt off the northwest coast of the Yucatan peninsula. Seas are 1 to 3 ft over the eastern Gulf, and 2 to 4 ft over the western Gulf. No widespread dense fog or smoke is reported.

The weak ridging will persist over the Gulf through Mon, then dissipate ahead of a cold front moving into the northern Gulf waters Tue. The front will sweep southeast of the Gulf through late Wed. Winds will increase to fresh to strong over the NE Gulf late Wed through Thu as strong high pressure settles over the Mid Atlantic states.


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

A shearline or old frontal boundary extends from eastern Cuba westward to west of Grand Cayman Island, Earlier ship observations and scatterometer data indicated strong winds north of the shear line. Recent scatterometer data showed moderate to fresh NE winds into the Windward Passage, and fresh to strong winds off northeast Colombia.

The shear line will meander and dissipate through today. Elsewhere fresh to strong tradewinds are expected near the coast of Colombia through Wed. N to NE Atlantic swell will move through the Caribbean passages E of Hispaniola through late today. A new cold front will move southward into the NW Caribbean Wed night, before stalling and weakening from central Cuba to Belize Thu.

A weak stationary front reaches from 26N65W to the Windward Passage. A second cold front reaches from 31N63W to 29N75W then is stationary to off Jacksonville Florida. Light to gentle winds are noted north of 24N, and moderate to fresh NE to E winds area noted south of 24N.

The weak stationary front will dissipate through late today. A second front will move south and stall along 24N by late today, before dissipating over the region tonight. A third front will move off the northeast Florida coast early Tue. Low pressure may form along the front by mid week, followed by strong to near gale force northerly winds. The front and low pressure will drift slowly eastward through late week.
