Altimeter data show seas of 8 to 10 ft in the aforementioned region. Latest scatterometter data show fresh to strong N to NE winds between the coast of NW Africa and both the Canary and Cape verde Islands. The remainder central and eastern subtropical Atlantic is under the influence of the ridge of the Azores High. NW swell associated with this front is producing seas to 9 ft N of 27N between 38W and 58W. A cold front extends from 31N45W SW to near 26N55W where it stalls and continue to near the Turks and Caicos Islands. See the Special Features above for information on an ongoing Gale Warning for the region of Agadir, Africa.Ī surface trough extends across the north-central Bahamas and support an area of fresh to strong E winds to the N and NE of the trough. Elsewhere, gentle to moderate winds will prevail. These winds will begin to pulse to fresh to strong at night starting Wed night. Moderate to fresh E winds are expected in the Gulf of Honduras through Wed. Moderate trade winds dominate the remainder Caribbean with seas in the 3 to 6 ft range.įor the forecast, the pressure difference between high pressure N of the area and lower pressure in NW Colombian will support fresh to strong trade winds in the south-central Caribbean, including the Gulf of Venezuela, through early next week. Fresh NE winds are in the Gulf of Honduras with seas to 3 ft while the remainder NW basin enjoys a light breeze. Seas within this area of strong winds range between 7 to 9 ft. Surface ridging N of the area extends into the northern half of the Caribbean and along low pressure in NW Colombia continue to support fresh to strong trade winds across the SE, south-central and portions of the SW basin. Otherwise, high pressure will dominate the Gulf waters through the forecast period producing gentle to moderate winds and slight to moderate seas, with the exception of moderate to fresh SE to S winds over the western Gulf. Otherwise, upper level diffluent flow support scattered showers and thunderstorms in the offshore waters between SE Louisiana and the Florida Panhandle.įor the forecast, fresh to locally strong winds will pulse near and to the NW of the Yucatan Peninsula each night into the early morning hours through Thu night due to local effects related to a thermal trough. Winds are moderate to locally fresh from the E across the remainder SW Gulf. Fresh to strong NE to E winds are along the coast and adjacent waters of the Yucatan Peninsula being supported by a thermal trough. High pressure of 1025 mb anchored over South Carolina extends a ridge SW across the Gulf of Mexico and provides gentle to moderate E to SE winds N of 23N. Scattered moderate convection is from 01N to 08N between 20W and 46W. The ITCZ continues from 05N18W to 05N30W to 02N50W. The monsoon trough passes extends from the coast of Guinea to 05N18W. Please, refer to the Meteo-France High Seas Forecast, that is on the website,, for details. The marine forecast from the Meteo-France consists of a warning for northerly gale-force winds, in the marine zone AGADIR, from 06/1500 UTC until 07/1200 UTC. Posted 3 months ago by NHC Forecaster Forecaster Cangialosi High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at /shtml/NFDHSFAT1.php * Formation chance through 5 days, low, near 0 percent. * Formation chance through 48 hours, low, near 0 percent. Regularly scheduled Tropical Weather Outlooks will resume on May 15, 2023, while Special Tropical Weather Outlooks will be issued as necessary during the off-season. No additional Special Tropical Weather Outlooks are scheduled for this system. Nevertheless, the system is expected to remain a strong non-tropical low during the next day or so, and additional information, including storm-force wind warnings, can be found in High Seas Forecasts issued by the National Weather Service. Therefore, it is unlikely that the low will transition to a subtropical or tropical cyclone. The low is expected to move northeastward today and northward tonight, bringing the system over much colder waters and across Atlantic Canada by early Tuesday. Although the cyclone is producing some thunderstorm activity near the center, it is embedded in a cold air mass with nearby frontal boundaries. Northwestern Atlantic: A non-tropical low pressure system centered over the northwestern Atlantic Ocean about 300 miles north of Bermuda is producing storm-force winds. Special Tropical Weather Outlook issued to discuss the potential for subtropical development over the northwest Atlantic. For the North Atlantic, Caribbean Sea and the Gulf of Mexico:
