Corrected SW N Atlantic Including the Bahamas section

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...

Winds and seas continue to diminish over the basin as high pressure builds in over the region. A rather weak front will move across the eastern Gulf Mon afternoon through Tue. High pressure building behind that front will allow for fresh to strong southeast return flow to become established off the Texas coast by mid week before weakening some Thu and Thu night.


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

A cold front extending from eastern Cuba to eastern Honduras will become stationary and weaken from the Windward Passage to northeast Nicaragua by early this evening. Fresh to strong northerly winds behind the front will shift southward to along and within about 180 nm east of the coast of Honduras this afternoon and tonight before diminishing to moderate to fresh winds on Mon and to mainly moderate winds Mon night. A weak trough will drift westward toward the Leeward Islands through early next week. Low pressure on the north side of the trough s is expected track northwestward across the northeast part of the Tropical N Atlantic waters Mon through early Wed. Strong east to southeast winds in the northeast quadrant of this low are forecast to impact the those waters Mon through early Wed. Scattered showers and isolated thunderstorms are expected with this feature. With the approaching trough and low, expect for a weaker gradient to allow for light to gentle winds to persist across the central and eastern Caribbean through the forecast period. Northeast swell will subside as it propagates through the eastern part of the Tropical north Atlantic from Wed through Thu night.


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

A cold front extends from near 31N72W to eastern Cuba. It is associated with an intensifying 999 mb low pressure system located near 30.5N76W as of 06Z this morning. The front will become stationary and weaken from near Bermuda to the Windward Passage by early this evening and into Mon. Ascat data from late last night revealed strong gale force west to northwest winds behind the front west of 77W and north of 29N and along with high wave heights in the range of 12-20 ft. These conditions are expected to spread eastward through this afternoon as the gale force winds diminish to just below gale force. Wave heights will remain high over much of the northwest part of the area through late tonight before they begin to subside on Mon, lowering to around 8 ft Mon night and Tue. A couple of weak and dry cold front will sweep across the area Mon through Wed. High pressure will build in across the area Wed through Thu night.
