Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1215 UTC Mon Mar 9 2026
Tropical Weather Discussion for North America, Central America Gulf of America, Caribbean Sea, northern sections of South America, and Atlantic Ocean to the African coast from the Equator to 31N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis.
Caribbean Sea Gale Warning: The pressure gradient between the Atlantic high pressure and the Colombian low will continue to support fresh to near gale-force trades across the central and eastern Caribbean through the early part of the week. Winds offshore of Colombia will pulse to gale-force Tue night. Seas of 8 to 12 ft are expected with the strongest winds.
Please read the latest High Seas Forecast issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.
The monsoon trough enters the Atlantic near 11N15W and extends to 02N22W. The ITCZ continues from 02N22W to the coast of Brazil at 03.5S39W. Isolated to widely scattered moderate convection is noted S of 03N between 18W and 31.5W.
An old frontal boundary remnant is near the coast of Texas and Louisiana, continuing to trigger showers and thunderstorms in the NW Gulf early today. Areas of dense fog with reduced visibilities is present in much of the N-central and NE Gulf coastal waters with nearshore and offshore observations reporting such. Light to gentle winds are found N of 26N and E of 90W along with seas of 3 ft or less, with moderate to locally fresh E-SE winds and 3 to 5 ft seas elsewhere.
For the forecast, a broad surface ridge extending across the basin will prevail through midweek. The pressure gradient between the ridge and low pressure over Mexico will support mainly moderate to fresh E to SE winds basin-wide, pulsing to between fresh and strong near the northern Yucatan and the western Gulf in the evenings, and slightly weaker winds overall in the northeastern Gulf. Seas will be slight to moderate through Wed. A cold front may impact the northwestern Gulf beginning Wed night, before moving across the basin through Fri night with increasing winds and seas behind it.
Please see Special Features section above regarding a developing Gale Warning in the south-central Caribbean.
A strong pressure gradient between the Colombian low and high pressure to the north is supporting fresh to strong trade winds over the central and eastern Caribbean. Winds are moderate to fresh across much of the remaining basin. Seas of 8-10 ft prevail in the central Caribbean per a pair of altimeter passes. Seas are moderate in the eastern and SW Caribbean, except locally rough near Atlantic passages, while slight to moderate seas prevail elsewhere.
For the forecast, the pressure gradient between a Bermuda High and a Colombian low will support fresh to strong trades across the eastern basin through Tue, and the central basin through Wed night. Winds offshore of northwestern Colombia will pulse to gale- force during the night-time hours Tue night. Fresh to locally strong NE to E winds will pulse near the Windward Passage through mid-week. Moderate to fresh winds will pulse in the Gulf of Honduras and Lee of Cuba through Wed night. Large easterly trade- wind swell from the tropical North Atlantic will keep rough seas near the Lesser Antilles through Wed night. Marine conditions will improve slightly by the end of the week as the pressure gradient weakens due to a weak cold front approaching the NW Caribbean.
Surface ridging dominates the central and western tropical Atlantic, supporting widespread moderate to fresh trade winds south of 27N. Pockets of locally strong trade winds are noted east of the Lesser Antilles. Rough seas in E swell are noted in this region as well as east of the Lesser Antilles. Elsewhere, the remnants of a frontal boundary are analyzed as a surface trough, extending from 31N33W to 24N39W. Fresh to strong NE winds are occurring N of 28N between the trough and 45W. Associated remnant rough seas are found N of 28N between 27W and 47W. Scattered showers and thunderstorms are possible N of 23N between 32W and 43W. Farther east, fresh to strong NE winds and rough seas in NE swell prevail off the coast of northwest Africa, supported by a strong pressure gradient between a high to the north over the Azores and lower pressures over northwest Africa. Elsewhere, gentle to moderate winds and moderate seas prevail over the rest of the basin.
For the forecast west of 55W, moderate to fresh easterly winds will prevail south of 25N through midweek, reaching strong north of Hispaniola into the Windward passage at times. Rough seas will prevail within these winds and east of the central and southeast Bahamas through Tue. Moderate or weaker winds can be expected elsewhere across the region. Southerly fresh to strong winds may develop off northern Florida Wed night ahead of a potential cold front. That front may move offshore Thu with fresh to strong winds and building seas behind it, weakening and slowing from near Bermuda to the northern Bahamas by late Thu night.
Our Tropical Weather reports - for the most part are put together only during tropical weather season. Our reports are based on a number of online sources and are based on our past experience dealing with tropical weather. We also occasionally include non-tropical weather that would affect the area / footprint that we cover. For additional information check out Crown Weather Services
