Special Features

Gale Warning East of 35W: A Gale Warning remains in effect for the Canarias and Agadir Marine Zones of Meteo France. The forecast calls for NE winds to Force 8 on the Beaufort Wind Scale, with severe gusts between the Canary Islands through at least 01/0000 UTC. Seas currently range from 9 to 13 ft N of 10N and E of 30W based on a recent altimeter pass. Higher seas of 12 to 15 ft are possible just N of the Canary Islands.

Central and Eastern Atlantic Significant Swell Event: A robust high pressure system near the Azores is maintaining fresh to near gale-force trade winds across the eastern and central Atlantic. Wind waves generated by these winds will continue to generate seas of 8 to 13 ft across most of the waters between 20W and 60W, with highest seas E of 40W. This event will persist through early next week, while drifting SW.

Monsoon Trough Itcz

The monsoon trough enters the Atlantic along the coast of Guinea near 11N14W, then extends southwestward to 05N18W. The ITCZ continues from 05N18W to the coast of Brazil near 04S38W. Scattered moderate convection is observed south of 06N and east of 30W.

Gulf Of America

A stationary front extends from the Florida Big Bend region to a 1013 mb low pres near 27N87W and then to the south Texas coast. A few showers and isolated thunderstorms are noted in the SE Gulf waters. A weak pressure gradient dominates the Gulf, resulting in moderate or weaker winds and slight to moderate seas.

For the forecast, the storm activity will progress southeastward this morning and weaken. The weak front will slowly sink southeastward and exit the basin tonight. Later, a strong high pressure system will build west-southwestward over the area from the N Atlantic beginning on Sun night, with the related gradient generally supporting moderate to fresh east to southeast winds across the Gulf. Locally strong winds will occur at night off N Yucatan Tue and Wed.

Caribbean Sea

A strong high pressure system centered over the central Atlantic combines with the Colombian low to support fresh to near gale- force trade winds over the central Caribbean. Seas are 7 to 10 ft with these winds. Moderate to fresh trades and moderate seas dominate the eastern Caribbean, while mainly gentle to moderate E to SE winds with moderate seas are noted over the NW part of the basin. Seas to 8 ft are noted across the Atlantic passages in the Lesser Antilles.

For the forecast, an expansive subtropical ridge over the central Atlantic will support fresh to near gale-force easterly trade winds and moderate to rough seas across the central and eastern Caribbean over the next several days. A tighter pressure gradient will initiate gale-force winds off Colombia at night Mon through at least late next week and support locally very rough seas. Fresh to strong trades expected elsewhere across most of the central and eastern portions of the basin. In the meantime, rough seas in mixed swell will prevail in the tropical N Atlantic through the forecast period, with seas to 12 ft reaching 55W Mon. Elsewhere, little change is expected with moderate to fresh trades continuing through the period.

Atlantic Ocean

A Gale warning is in effect E of 35W. Please, see the Special Features section for more information.

A nearly stationary front has exited the coast off NE Florida, supporting numerous showers and isolated thunderstorms W of 75W and N of 27N. Meanwhile, a 1034 mb high pressure system located near the Azores extends an extensive ridge across the entire Atlantic forecast waters. The tight pressure gradient between the ridge and lower pressures in the deep tropics and western Africa result in fresh to near gale-force easterly winds and rough to very rough seas over much of the central and eastern Atlantic. Moderate to fresh easterly winds and rough seas are found north of 20N and between 50W and 65W. Elsewhere, moderate or weaker winds and moderate seas are prevalent.

For the forecast west of 55W, the aforementioned front is expected to move slowly southeastward and weaken across the waters W of 65W through Sun night before dissipating. Elsewhere, high pressure over the central Atlantic continues to maintain control over much of the western Atlantic while rough seas prevail over the SE waters. Another cold front is expected to enter the northern waters early next week and gradually shift southeastward and weaken. Fresh to near gale-force easterly winds and rough to very rough seas, peaking around 14 ft, are forecast behind the front Mon through Tue night north of 27N. High pressure will build by the middle of next week resulting in moderate to fresh winds and rough seas over much of the basin.
