...SPECIAL FEATURES...

...CENTRAL ATLANTIC GALE WARNING...

A dying occlusion and cold front extends from a 1009 mb low pressure near 26N59W to northeast of the Windward Islands near 17N56W. A trough extends from the end of the dying cold front to the southeast Caribbean near 12N64W. A broad high pressure ridge NE of the front is inducing a tight pressure gradient along and northeast of the front. Strong to gale force winds are noted within 300 nm east of the front, N of 21N and W of 43W. Seas within this zone are 10 to 16 ft. Scattered moderate convection is also noted east of the front from 17N to 31N between 44W and 52W. The surface low pressure will move SE and continue to weaken. The front will also continue to drift eastward and weaken. This will cause winds to drop below gale force later this afternoon. The strong winds will continue through the weekend as the next frontal system moves across the western Atlantic.

...ATLANTIC SIGNIFICANT SWELL EVENT...

Very large northerly swell, that has originating in the NE Atlantic offshore of Europe, is beginning to enter the far NE Atlantic waters S of 31N and E of 40W. Seas will quickly build to 12 ft and greater and peak around 18 feet tonight. Seas of 12 ft will reach as far W as 46W early Fri while merging with the very rough seas with the gale force event mentioned above. The seas will move as far S as 18N by Fri night before moving eastward beyond 35W Fri night into Sat morning.

Please, read the latest High Seas Forecast, at www.nhc.noaa.gov/text/MIAHSFAT2.shtml, for more information.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal plains of Sierra Leone near 09N13W to 00N26W. The ITCZ continues from 00N26W to 00N30W to the coast of Brazil near 01S46W. Scattered moderate convection is noted from 01N to 06N between 12W and 23W and from 02S to 02N between 38W and 45W.

...GULF OF MEXICO...

A slow moving cold front extends from Tampa Bay, Florida to the Yucatan Channel. Scattered showers are moving across the extreme southeast Gulf of Mexico along and ahead of the front. The stronger thunderstorms have moved into the NW Caribbean and over Cuba. Fresh to strong NW winds prevail behind the front across the central and eastern Gulf with moderate to fresh winds ahead of the front. Seas in this area range 7 to 10 ft. In the western Gulf, high pressure continues to build behind the front. Light to gentle winds are occurring along the Texas and Mexico coast W of 94W under the influence of the high. Seas range 2 to 4 ft in this area.

For the forecast, a strong thunderstorms will continue along the front across the SE Gulf this morning, as the front moves SE and clears the Gulf basin later today. Fresh to strong NE winds and moderate to rough seas will follow the front across the Gulf. Winds and seas will subside late tonight into Fri as high pressure moves across the northern Gulf in the wake of the front. Looking ahead, the high pressure will shift E and support fresh E to SE winds across the western Gulf Sat through Mon.

...CARIBBEAN SEA...

A cold front stretches to the east of the Yucatan and Belize. Ahead of the front, a cluster of strong thunderstorms are noted in the NW Caribbean from 17N to 22N between 83W and 86W. Moderate to fresh NW winds are noted behind the front along the coastline in addition to the Gulf of Honduras. Seas in the Yucatan Channel are to 5 ft with 2 to 4 ft seas across the rest of the NW basin. Meanwhile, light to gentle winds prevail across the rest of the Caribbean. Northwest swell that have impacted Passages continue to produce seas up to 5 ft in the eastern Caribbean E of 68W. Otherwise, seas are 3 ft or less.

For the forecast, the cold front will reach from eastern Cuba to NE Honduras by Fri morning. Fresh to strong winds and rough seas will immediately follow the front across the NW Caribbean today and tonight. Winds and seas will diminish Fri across NW portions as the front reaches the the NE coast of Cuba to NE Honduras, then weakens from Hispaniola to the Honduras- Nicaragua border on Sat. High pressure building north of the region in the wake of the front will support fresh to strong NE winds in the lee of eastern Cuba and across the Windward Passage Fri night through Sat evening. Winds and seas will then diminish there Sat night. Moderate N swell is moving through the NE Caribbean Passages and adjacent Tropical Atlantic waters this morning and will gradually subside through early Fri. Strong trade winds and rough seas will pulse off the coast of Colombia and the southern coast of Hispaniola Sat and Sun as the high pressure settles NE of the Bahamas.

Winds are moderate to fresh along the entire Florida coast, including the Florida Keys, to 75W. Seas in this area range 4 to 7 ft. Between this system and the frontal system producing gale force winds in the central Atlantic, a 1015 mb high pressure is near the Turks and Caicos. Winds are light to gentle under this high and to the 1009 mb low pressure mentioned in the Special Features section. Seas range 6 to 10 ft.

In the eastern Atlantic, a cold front extends from 31N24W to 31N37W. The latest ASCAT data depicted fresh to strong W to NW winds behind the front with moderate to fresh W winds ahead of it.

Gentle to moderate winds prevail with 6 to 9 ft seas.

For the forecast W of 55W, the broad low pressure SE of Bermuda centered near 26N59W will meander then weaken to a trough and move slowly NE and east of 55W Fri night. Large northerly swell dominates the waters W of 60W and will gradually subside through early Fri. An associated dissipating frontal boundary extends from 31N65W to 26N54W to the central Lesser Antilles. An area of strong to gale- force S to SE winds, rough to very rough seas, and scattered strong thunderstorms remains active to the east of the front, N of 20N. SE gales occurring N of 26N will move N of the area this evening, while the front gradually shifts to the east of 55W by Fri morning. Farther west, a cold front has moved off the northeast Florida coast. This front will reach from Bermuda to eastern Cuba by midday Fri, from 31N55W to the Mona Passage by Sat morning, then move east of the area early Sun.
