The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2242 UTC. ...SPECIAL FEATURES... Gulf of Mexico Storm Warning: Fresh to locally strong NE winds prevail across the E and central Gulf. The next cold front, associated with low pressure moving through the southern United States, will enter the NW Gulf Thu morning, promoting moderate to fresh N to NE winds across much of the basin. Winds will increase to strong speeds offshore of Veracruz and Tampico late Thu morning before reaching gale force early Fri, and rough to very rough seas will accompany the winds. Winds and seas will diminish on Sat in this area. W Atlantic Gale Warning: A cold front from just W of Bermuda to the NW Bahamas to the Florida Straits will progress eastward through Thu morning, with strong to gale-force winds and very rough seas in its wake, mainly N of 27N and W of 70W. Earlier this morning scatterometer data revealed 35 to 40 kt NNW winds near 30N81W just offshore of NE Florida. A SOFAR buoy recorded 13 ft seas near 30N79W at 1200 UTC. Fresh to locally strong SW winds will occur ahead of the front this evening. Winds and seas will quickly subside tonight and Thu. Caribbean Sea Gale Warning: Widespread fresh to strong trades and rough seas will occur across the southwestern, central and eastern Caribbean into this weekend. Winds will pulse to gale force offshore of Colombia tonight through Thu morning, with winds reaching near-gale force in this area each night Thu through this weekend. Seas will peak 10-13 ft just northwest of Colombia tonight through Thu. For more details on these features, please refer to the latest NWS High Seas Forecast, that is issued by the National Hurricane Center, at the website: www.nhc.noaa.gov/text/MIAHSFAT2.shtml Eastern Atlantic Large Swell: Large long-period N swell is impacting our NE waters, east of 30W and north of 22N. This 12-second period swell is forcing seas up to 16 ft, along our N border and near 22W. A SOFAR buoy recorded seas of 16 ft at 31N22W at 1200 UTC. The large swell will gradually diminish into Thu. For more details on the large swell, please refer to the latest MeteoFrance High Seas Forecast at the website: wwmiws.wmo.int/index.php/metareas/display/2 ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic from near 07N12W and extends southwestward to 01N18W. The ITCZ continues from 01N18W to 01S46W. Scattered moderate convection is noted from 01S-05N and east of 27W. ...GULF OF MEXICO... Please refer to the Special Features section for details on the Gale Warning in effect. Fresh to locally strong NE winds prevail in the east and southeast Gulf with seas 10 to 16 ft. Moderate to gentle winds prevail over the the northeast and north Gulf with seas 4 to 8 ft. No significant deep convection is occurring. For the forecast, fresh to locally strong NE to NW winds occurring from the southwestern through eastern Gulf of Mexico will slowly diminish through tonight, in the wake of a cold front in the northwestern Caribbean. Very rough seas associated with these winds will subside Thu morning. The next cold front, associated with low pressure moving through the southern United States, will enter the northwestern Gulf Thu morning, promoting moderate to fresh N to NE winds across much of the basin. Winds will increase to strong speeds offshore of Veracruz and Tampico late Thu morning before reaching gale force early Fri, and rough to very rough seas will accompany the winds. Winds and seas will diminish by Sat in this area. Looking ahead, moderate to fresh NE to SE winds are expected across the basin this weekend as high pressure builds in the south-central United States. Locally strong SE winds and rough seas will be possible offshore of Texas late Sat into Sun. ...CARIBBEAN SEA... Please refer to the Special Features section for details on the Gale Warning. A cold front extends from western Cuba through northeastern Honduras. In its wake, fresh to strong N winds and seas 8-14 ft are occurring in the Yucatan Channel, with moderate to fresh winds and seas 4-8 ft farther south. Broad surface ridging is supporting fresh to strong trades over the central Caribbean and moderate to fresh winds over the eastern part of the basin with seas 8-12 ft. Isolated moderate convection is occurring within 60 NM of the front. For the forecast, widespread fresh to strong trades and rough seas will occur across the southwestern, central and eastern Caribbean into this weekend. Winds will pulse to gale force offshore of Colombia tonight into Thu morning, with winds reaching near-gale force in this area each night Thu through this weekend. In addition, a long-period E swell will lead to rough seas through the Atlantic Passages through this weekend. Elsewhere, a cold front currently extending from western Cuba through northeastern Honduras will progress slowly southeastward into Thu before dissipating. Fresh to locally strong NE winds and seas of 8 to 14 ft will occur in the wake of the front, including through the Yucatan Channel, through tonight. Moderate to fresh NE winds, pulsing to strong at times, and rough seas will occur in the northwestern basin through Fri as troughing prevails in the region. Looking ahead, widespread strong N to NE winds and building seas are slated to develop across the northwestern Caribbean by this weekend as a cold front moves through the Gulf of Mexico. Strong winds and building seas will expand into the central Caribbean through the weekend. ...ATLANTIC OCEAN... Please refer to the Special Features section for details on the Gale Warning in effect for the W Atlantic, and the large north swell event in the eastern Atlantic. A 1029mb high is centered at 32N42W with ridging extending southeastward to 18N20W and west-southwestward to 21N75W. The equatorward pressure gradient is forcing fresh to strong trades from 07N-24N west of 26W with seas 8-12 ft. A strong cold front stretches from 31N70W over the NW Bahamas to the Florida Straits. Strong to gale-force winds and very rough seas are occurring in its wake, mainly N of 27N and W of 73W. Isolated moderate convection is located within 60 NM of the front. Fresh to locally strong SW winds are occurring ahead of the front north of 29N. Finally, in the E Atlantic a trough extending from 31N14W to 23N17W is forcing fresh to strong N winds north of 24N and east of 29W along with large to very large N swell, as described above. Elsewhere, winds are moderate or weaker and seas 5-8 ft. For the forecast, a cold front extending from just west of Bermuda to the NW Bahamas to the Florida Straits will progress eastward through Thu morning, with strong to gale-force winds and very rough seas expected in its wake, mainly N of 27N and W of 70W. Fresh to locally strong SW winds will occur ahead of the front today. Elsewhere, fresh to strong trades and rough seas will prevail through the weekend south of 23N. Low pressure is expected to form off the east coast of Florida on Thu, and moderate to fresh N to NW winds will occur to the north and west of the low through Fri morning. The low will strengthen and move northeastward Fri into Sat, promoting widespread fresh to strong N to NW winds north of 22N and west of 70W by Fri night. An associated cold front will trail the low pressure and move eastward this weekend, producing fresh to locally strong N to NE winds and rough seas in its wake. $$ KRV
