Special Features

Gale Warning E of 35W: A tight pressure gradient between a 1030 mb high pressure system west of the Azores and lower pressure over NW Africa will support strong to gale-force N-NE winds and rough to very rough seas in the Agadir region from 01/0600 UTC to at least 01/1200 UTC. Fresh to strong winds and rough seas will persist off Morocco into early Wed. For more details, refer to the Meteo-France High Seas Forecast listed on their website https: //wwmiws. wmo. int

Tropical Waves

The axis of an eastern Atlantic tropical wave is near 17/18W, south of 19N, moving westward at 10 to 15 kt. Scattered moderate and isolated strong convection is noted from 06N to 15N between 13W and 20W.

The axis of an Atlantic tropical wave is near 39W, south of 19N, moving westward at 10 to 15 kt. No significant convection is noted near this wave.

The axis of a central Caribbean tropical wave is near 70W, south of 19N, moving westward around 20 kt. Isolated moderate convection is near the wave axis.

Monsoon Trough Itcz

The monsoon trough enters the Atlantic off the coast of Africa near 15N17W and continues to 11N22W to near 10N42W. The ITCZ extends from 10N42W to 13N60W. Aside from convection noted in the tropical waves section above, scattered moderate convection is noted from 04N to 11N between 20W and 30W.

Gulf Of America

A weak cold front extends from near Brooksville, Florida to Galveston, Texas. Moderate winds prevail N of the front, where seas are in the 2-3 ft range. Light to gentle winds, and seas of 1-2 ft prevail elsewhere. For the forecast, the front will continue to drift southward into the central Gulf through Mon, then will stall and dissipate through Tue. The front will be a focus for showers and thunderstorms into mid week. Elsewhere, the weak gradient in place will maintain mainly gentle to moderate winds and slight to locally moderate seas through the period.

Caribbean Sea

Fresh to strong winds are noted over the south central Caribbean. Moderate to fresh winds are over the remainder of the central Caribbean waters. Gentle to moderate winds are noted over the remainder of the Caribbean waters, except light to gentle winds over the far NW Caribbean. Seas are in the 6-8 ft range over the south central Caribbean and 3-5 ft over the north central Caribbean. Elsewhere, seas of 2-4 ft prevail.

For the forecast, Atlantic high pressure in combination with low pressure over northern Colombia will support fresh to strong trades along with moderate to locally rough seas across much of the central Caribbean through this week.

Atlantic Ocean

A stationary front extends across the western Atlantic through 31N72W to near Fort Pierce, Florida. Moderate to fresh winds, and seas of 4-7 ft prevail north of the front. Troughing prevails elsewhere N of 20N and W of 35W. High pressure dominates the waters N of 20N and E of 35W. Moderate to fresh winds are noted N of 18N and E of 40W, reaching strong speeds off the coast of Africa. Seas over these waters are in the 5-7 ft range. Elsewhere, light to gentle winds, and seas of 3-5 ft prevail. For the forecast west of 55W, the front will persist through most of this week. Expect fresh to strong winds with moderate to rough seas north of the front into Tue, along with scattered showers and thunderstorms. Elsewhere, the Atlantic ridge will dominate the pattern from the central Atlantic through the Bahamas, supporting gentle to moderate breezes and mostly moderate seas.
