Special Features

Central Atlantic Significant Swell: Residual NW swell will maintain seas near 12 ft at the central Atlantic north of 30N between 53W and 58W today. These seas will subside below 12 ft by early this evening.

Please read the latest High Seas Forecast issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more information.

Monsoon Trough/ITCZ

A monsoon trough remains mostly over the African Continent. An ITCZ extends westward from just southwest of Liberia across 05N25W to 06N45W. Scattered to numerous moderate with isolated strong convection is observed near the ITCZ from 04N to 07N between 10W and 18W. Scattered moderate convection is seen farther west from 04N to 07N between 16W and 36W.

The eastern end of the East Pacific monsoon trough is triggering scattered showers and isolated thunderstorms across the Caribbean waters near Panama.

Gulf Of America

A surface trough is causing scattered showers at the western Bay of Campeche. Otherwise, a 1022 mb high near the central Gulf continues to dominate much of the Gulf with gentle to moderate anti-cylconic winds and 1 to 3 ft seas.

For the forecast, moderate or weaker winds and slight seas will prevail over the basin through Fri morning as high pressure builds over the central Gulf of America. Fresh to locally strong SW to W winds and moderate seas will develop over the northern Gulf on Fri as a warm front, associated with a low pressure system moving through the southern U.S., lifts northward. A cold front trailing the low is slated to enter the northern Gulf on Sat, leading to moderate N winds behind the front. High pressure will build over the basin in the wake of the front Sun into next week

Caribbean Sea

A surface trough is producing scattered showers and isolated thunderstorms at the north-central basin. Convergent trades are triggering scattered showers at the Gulf of Honduras and near Jamaica. Moderate to fresh NNE to E trades and seas of 5 to 8 ft are present at the south-central and west-central basin. Gentle to moderate with locally fresh NNE to E to ESE trades and 3 to 5 ft seas prevail elsewhere in the Caribbean Sea, including the Windward Passage.

For the forecast, moderate to fresh N to NE winds and moderate seas will prevail over the central and western basin, including the Windward Passage, through Fri as high pressure builds over the Gulf of America to the north. Elsewhere, fresh to locally strong trade winds are expected in the south-central basin through Sat as low pressure anchors over northern Colombia. Moderate or weaker winds and moderate seas are then expected over much of the basin for Sun..

Atlantic Ocean

See the Special Features section at the beginning on rough to very rough seas at the central Atlantic.

A cold front extends from the north-central Atlantic across 31N55W to 26N64W, then continues as a stationary front to northeast of the southeast Bahamas at 23N69W. Widely scattered showers and isolated thunderstorms are occurring near and up to 110 nm southeast of this boundary. Convergent southerly winds farther east are generating similar convection north of 22N between 54W and 59W. Refer to the Monsoon Trough/ITCZ section for additional convection in the Atlantic basin.

Moderate to fresh W to NW winds and 5 to 7 ft seas are present east of Florida, north of 27N between 64W and the northeastern Florida coast. Fresh with locally strong S to SW winds and seas at 8 to 12 ft in residual NW swell exist north of 27N between 48W and 58W. Otherwise, moderate to gentle N to E to SE winds and 4 to 6 ft seas are noted north of 20N between 35W and the Florida/southern Georgia coast. For the tropical Atlantic from 06N to 20N between 35W and the Lesser Antilles, moderate with locally fresh NE to SSE winds and seas at 6 to 8 ft in moderate to large N swell exist. For the remainder of the Atlantic west of 35W, gentle SE to S winds with seas at 4 to 6 ft in mixed moderate swell exist.

For the forecast west of 55W, the aforementioned cold front will progress eastward today, and moderate to fresh SW winds are expected east of the front, north of 27N, through this evening. Rough seas associated with this front, north of 26N and east of 62W, will slowly subside from west to east into early Fri. Locally very rough seas over 12 ft will be possible north of 30N and east of 58W through this afternoon. Elsewhere, fresh to strong W winds and locally rough seas occurring offshore of northern Florida will expand eastward today as a cold front passing north of the waters moves eastward. Looking ahead, fresh to strong SW winds and rough seas are expected to develop offshore of northern and central Florida on Sat, ahead of a cold front moving through the southeastern U.S. The front is forecast to enter the northwestern tropical Atlantic later this weekend, supporting fresh to strong N winds and locally rough seas behind the front. These winds and seas will expand southeastward into early next week.
