Special Feature

Gale Warning E of 35W: Meteo-France has issued Gale Warnings for the marine zones of Agadir through 14/12Z and Tarfaya through 14/00Z. The pressure gradient between a 1029 mb high pressure located midway between the Azores and the Madeira Islands and relatively lower pressures in NW Africa supports these gale force winds (Force 8 on the Beaufort Wind Scale) with severe gusts. Very rough seas, in long period NW swell, are also reaching this area.

Monsoon Trough Itcz

The monsoon trough enters the Atlantic near 09N13. 5W, then continues SW to near 00. 5S28W. The ITCZ extends from 00. 5S28W to near 01S42W. Scattered moderate convection is noted S of 04N between 25W and 50W.

Gulf Of America

High pressure centered over the western Atlantic extends a ridge across Florida into the Gulf region. Under the influence of this system, fresh NE to E winds and moderate seas are noted over the SE Gulf, including the Straits of Florida. Moderate to fresh E winds are observed W of the Yucatan peninsula associated with a thermal trough. Moderate to locally fresh E to SE winds and moderate seas are observed elsewhere.

For the forecast, the aforementioned high pressure over the western Atlantic extends a ridge across Florida into the Gulf region. This system will maintain moderate to fresh E to SE winds and mostly moderate seas through Fri. Expect stronger winds to pulse across the SE part of the Gulf, including the Florida Straits, through Tue, and off the Yucatan Peninsula each night through Wed, driven by local effects associated with a thermal trough.

Caribbean Sea

A stationary front over the Atlantic that reaches Hispaniola and a pre-frontal trough are helping to induce scattered to numerous showers and thunderstorms over Hispaniola, the Mona Passage and Puerto Rico. High pressure over the western Atlantic combined with the Colombian low supports fresh to strong trades over the south- central Caribbean, including the Gulf of Venezuela. Seas are 8 to 9 ft offshore Colombia. Fresh to strong winds and moderate seas are also noted in the Windward Passage and in the lee of Cuba. Moderate with locally fresh NE to E winds and 3 to 6 ft seas prevail elsewhere in the Caribbean Sea.

For the forecast, high pressure over the western Atlantic combined with the Colombian low will maintain fresh to strong trade winds and rough seas over the south-central Caribbean and near the coast of Colombia today, then mainly fresh winds are expected through Wed night. Fresh to strong northeast winds and building seas will prevail south of Cuba, in the Windward Passage, and south of Hispaniola through the the middle of the week. Winds and seas will diminish across the basin late in the week. week. Winds and seas will diminish across the basin late in the week.

Atlantic Ocean

Please read the Special Features section about Gale Warnings off Morocco.

Scattered to numerous showers and thunderstorms are active along a stationary front that extends from 31N54W to Hispaniola. Fresh to near-gale NE winds and seas of 8 to 11 ft are found near and behind the aforementioned frontal boundary, with the exception of moderate E winds and 5 to 7 ft seas off NE and central Florida. High pressure follows the front and extends a ridge across the western Atlantic and Florida into the Gulf of America. E of the front, high pressure of 1029 mb located midway between the Azores and the Madeira Islands dominates the remainder of the Atlantic forecast region. Moderate to fresh N to NE winds are noted per scatterometer data N of 10N and S of a line from 30N19W to 24N40W. Seas of 6 to 10 ft are within these winds. Elsewhere, moderate or weaker winds and moderate seas prevail.

For the forecast west of 55W, scattered to numerous showers and thunderstorms are active along a stationary front extending from near 31N54W to Hispaniola. The front will dissipate late today but a frontal trough will persist reaching Puerto Rico by this evening. Then, the frontal trough will move westward through Wed while weakening. Fresh to strong NE winds and rough seas will persist west of the front/trough mainly south of 27N through midweek, then diminishing through Fri.
