Gulf of Mexico Storm Warning: As of 1500 UTC, a cold front has passed across the Gulf of Mexico as of this morning, leaving its wake fresh to strong NE winds in 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. The ASCAT scatterometer measured 35-40 kt NNW winds near 30N81W just offshore of NE Florida at 1428 UTC this morning. A SOFAR buoy recorded 13 ft seas near 30N79W at 1200 UTC. Fresh to locally strong SW winds will occur ahead of the front today. 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 12-14 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 32W 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 coastal Liberia near 15N10W to 03N18W. The ITCZ continues from 03N18W to 01S41W.

As of 1500 UTC, a cold front has passed across the Gulf of Mexico as of this morning, leaving its wake fresh to strong NE winds in the E and central Gulf and strong to near gale NW winds in the SW Gulf. 12 ft seas cover the Gulf south of 27N with peak seas of 20 ft in the Bay of Campeche. No significant deep convection is occurring. For the forecast, strong to near-gale force 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.

Locally strong winds and rough seas will be possible offshore of Texas by early Sun. ...CARIBBEAN SEA... Please refer to the Special Features section for details on the Gale Warning. A cold front extends from W Cuba to the coast of Honduras. In its wake, strong N winds and seas 8-12 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 E and central Caribbean 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 through Thu morning, with winds reaching near- gale force in this area each night Thu through this weekend.
