Special Features

Caribbean Gale Warning: Strong to near-gale force E winds continue off the NW coast of Colombia, with seas peaking near 12-13 ft. Winds will pulse up to gale-force again later this evening and overnight before diminishing later Wednesday morning. These pulses of stronger winds offshore Colombia will occur each evening through Friday, with gusts to gale force possible. Please refer to the latest NWS High Seas Forecast issued by the National Hurricane Center at the website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml, for more details.

Agadir Gale Warning: An enhanced pressure gradient between a 1036 mb high centered near 33N28W and lower pressure over N Africa will support a round of N to NE gale-force winds between the Canary Islands and the coast of Morocco. A Gale Warning is in effect until 2100 UTC today. For more details, refer to the Meteo-France High Seas forecast listed on their website: https://wwmiws.wmo.int.

Monsoon Trough/ITCZ

The monsoon trough enters the Atlantic near 09N13W and continues SW to 05N19W. The ITCZ continues from 05N19W to 01N50W. Scattered moderate convection is noted from 00N to 04N between 20W and 50W.

Gulf Of America

A cold front enters the Gulf from the Big Bend of Florida to near 29N86W. A pre-frontal surface trough extends from just north of Tampa Bay to near 27N88W. Another surface trough extends across the W Gulf from the Bay of Campeche to near 23N96W to 26N94W. Moderate to locally fresh winds in cyclonic flow are occurring in the central to E Gulf around the cold front and pre-frontal trough. Moderate to fresh E to SE winds persist across the W Gulf, also in cyclonic flow around the surface trough. Slight seas prevail across the basin.

For the forecast, high pressure across the basin will generally support light to gentle SE to S winds over the western and central Gulf, and gentle to moderate winds over the eastern part of the basin into Wed. A surface trough will develop over the Yucatan Peninsula and move into the Bay of Campeche nightly through early this week, supporting pulses of fresh to locally strong winds over adjacent waters. A cold front will skirt the NE Gulf early today. High pressure building into the basin in its wake will lead to moderate to fresh southeast winds and building seas across the NW Gulf by Thu.

Caribbean Sea

A Gale Warning is in effect offshore Colombia. Please refer to the Special Features section above for more information.

Aside from the area of gale force winds, fresh to strong E winds prevail over the central and eastern Caribbean, with seas in the 7-11 ft range. Moderate to fresh E winds and seas of 4-7 ft are found across the remainder of the basin from the Gulf of Honduras across the W Caribbean to the Yucatan Channel.

For the forecast, fresh to strong E to NE winds offshore of Colombia and Venezuela will pulse to gale force offshore of Colombia tonight. These winds will then pulse to near gale force at night through Fri. Fresh E winds in the Gulf of Honduras will diminish to moderate speeds this afternoon.

Atlantic Ocean

A Gale Warning is in effect for the waters between the Canary Islands and the Moroccan Coast. Please refer to the Special Features section above for details.

High pressure dominates the Atlantic discussion waters. Fresh to strong winds prevail over much of the Atlantic waters south of a line running from the Canary Islands to the northern coast of Puerto Rico. Seas across this large region are 8-11 ft. To the north of this line, moderate to fresh winds in anticyclonic flow are observed, along with moderate seas. Areas S of another line running from the coast of Senegal near Dakar to the N coast of Brazil near Sao Luis are seeing mainly moderate N to NE winds and seas of 6-10 ft.

For the forecast west of 55W, high pressure over the western Atlantic will support gentle breezes and slight to moderate seas north of 22N through Wed. The area of high pressure will shift eastward enabling a weak cold front to move off the northeast Florida coast early today before dissipating. Fresh to locally strong winds are likely to pulse off the northern coast of Hispaniola into Wed. Another cold front may move into waters between northeast Florida and Bermuda Wed. High pressure will build in the wake of the front, bringing an increase in winds across much of the waters S of 28N by the end of the week and with little change in marine conditions expected into Sat night.
