Monsoon Trough Itcz

The monsoon trough enters the Atlantic from the coast of Sierra Leone near 08N13W and continues southwestward to 00N25W. The ITCZ then continues from that point to the coast of Brazil at 03S39W. Scattered moderate isolated strong convection is noted within 240 nm either side of the boundaries.

Gulf Of America

A cold front stretches from Cape Coral, Florida SW to 24N90W to Tampico, Mexico. Fresh to strong NE to E winds and moderate to rough seas prevail behind the front over the NE basin E of 89W. Moderate to fresh NE winds are ongoing in the E Bay of Campeche with seas to 6 ft. Elsewhere winds are moderate or weaker and seas slight to moderate.

For the forecast, the cold front will continue to bring fresh to strong NE winds and moderate to rough seas across the NE and then the SE Gulf through this evening as the front departs the area. As a broad ridge builds in the wake of the front, moderate to fresh E to SE winds and moderate seas will be sustained over the E Gulf through Thu night. Moderate to locally fresh SE winds is forecast for the western half of the Gulf with locally strong east winds off the northern Yucatan Peninsula due to a trough that will move every night to the Bay of Campeche.

Caribbean Sea

The pressure gradient between high pressure building in the wake of the Gulf of America cold front and the Colombian low is supporting fresh to near gale-force NE to E winds off Colombia and fresh to strong NE winds in the Gulf of Venezuela. Winds of similar speed are ongoing across the Windward Passage, the lee side of Cuba and south of Hispaniola. Elsewhere, moderate or weaker winds prevail.

For the forecast, the gradient of pressure between a ridge extending to the northern Caribbean and the low pressure over NW Colombia will continue to support strong to near gale-force NE to E winds and rough seas offshore Colombia through Thu night. Fresh to strong NE winds in the lee side of Cuba, the Windward Passage, and south of Hispaniola will prevail through the end of the forecast period due to strong high pressure that will build in the wake of a cold front moving through the SW N Atlantic waters through Wed.

Atlantic Ocean

A strong cold front extends from 31N65W SW to Boyton Beach, Florida. Strong to near gale-force NE winds and rough to very rough seas to 15 ft follows the front and is currently affecting the offshore waters N of the Bahamas and west of 63W. Ahead of the front, moderate to fresh NE winds and moderate seas prevail while further east, a pre-frontal trough, is supporting scattered showers. The remainder central and eastern subtropical Atlantic waters are under the influence of the Azores ridge, which tightens the pressure gradient and supports fresh to strong NE to E winds and moderate to rough seas extending from the NW coast of Africa to about 37W. Moderate or weaker winds and moderate seas are elsewhere.

For the forecast west of 55W, the cold front will continue to move SE through early Tue morning, bringing strong to near gale- force N to NE winds and rough to very rough seas across the offshore waters. The front is forecast to stall from the central Atlantic to the SE offshore waters early Tue morning and gradually weaken until dissipation by Wed night. Strong high pressure building in the wake of the front will continue to bring fresh to strong NE winds and rough seas to the offshores waters E of the Bahamas and across the Great Bahama Bank beyond Thu night.
