653 AXNT20 KNHC 020400 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Tue Jun 2 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. Based on 0000 UTC surface analysis and satellite imagery through 0355 UTC. ...SPECIAL FEATURES... Atlantic Gale Warning: Low pressure and an attendant cold front moving S of 31N will reach from Bermuda to the NW Bahamas by late Tue. Strong SW winds will develop ahead of the front Tue, increasing to gale-force SE of Bermuda by afternoon. Seas will build in this area to very rough. The front will stall Tue night, and winds will fall below gale force by Wed morning. Please read the latest High Seas and Offshore Waters Forecast issued by the National Hurricane Center at websites - https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and https://www.nhc.noaa.gov/marine/offshores.php for more details. ...TROPICAL WAVES... An eastern Atlantic tropical wave is along 36W, south of 16N and moving westward around 10 kt. A few showers are noted near the trough axis. A new tropical wave has been analyzed along 48W, south of 16N, moving westward at 10 to 15 kt. No convection is presently associated with this wave. A western Caribbean tropical wave is along 82W, south of 16N, moving westward at around 5 kt. Associated convection is confined to inland portions of Central America and the waters of the eastern Pacific basin. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Guinea-Bissau near 11N15W and continues southwestward to 06N28W. The ITCZ extends from 06N28W to 06N34W and then from 05N37W to near 02N50W. Scattered moderate convection is evident from 02N to 12N and east of 21W. ...GULF OF AMERICA... Divergence aloft, tropical moisture and diurnal heating support scattered showers and isolated thunderstorms across the central and eastern Gulf and the Yucatan peninsula. The weak pressure gradient forces moderate to locally easterly winds and seas of 1-3 ft over much of the western Gulf, west of 90W. Elsewhere, moderate or weaker winds and moderate seas prevail. For the forecast, a modest ridge will continue to dominate the Gulf waters until Wed morning, supporting gentle to moderate easterly to southerly winds. A late-season cold front will enter the northeastern Gulf Wed night, then stall from near Punta Gorda, Florida to New Orleans, Louisiana through Thu night before dissipating Fri. Anticipate fresh to strong E to SE winds and rough seas behind this front. By Fri night, ridging should rebuild across the central and northeastern Gulf, resuming gentle to moderate E to SE winds and moderate seas for the entire Gulf. An upper-level trough across the western Gulf will continue to support showers and thunderstorms across the eastern and central Gulf through midweek. ...CARIBBEAN SEA... A recent scatterometer satellite pass captured near gale-force easterly winds, up to 33 kt, off northern Colombia. This is due to the very tight pressure gradient between the expanding 1032 mb high pressure system south of the Azores and very low pressures in northern Colombia. Fresh to near gale-force easterly trade winds and rough seas are found in the central Caribbean. Fresh to locally strong easterly breezes and moderate seas are noted in the eastern Caribbean and Gulf of Honduras. Elsewhere, moderate or lighter winds and slight to moderate seas prevail. For the forecast, tight gradient between the Atlantic ridge and Colombian low will support fresh to strong trade winds and moderate to rough seas at the central and part of the southwestern basin through Wed morning. Winds and seas will diminish slightly starting late Wed as the ridge north of the basin weakens. by Thu. Fresh to strong winds with moderate seas are expected at the Gulf of Honduras through Fri night. Gentle to moderate E to SE winds with slight to moderate seas will prevail for the rest of the Caribbean Sea through the end of the week. ...ATLANTIC OCEAN... Please read the Special Features section about a Gale Warning for waters southeast of Bermuda Tue evening. A broad 1009 mb low pressure system is analyzed near 30N75W and a cold front extends from the low to near the central coast of Florida. A warm from extends from the low to 28N69W. Scattered moderate to isolated strong convection is present off SE Florida and also north of 25N and between 61W and 73W. Moderate to locally strong cyclonic winds and seas of 5-8 ft are occurring north of 26N and west of 68W. Farther east, a stationary front extends from 31N58W to the warm front. Moderate to locally fresh S-SW winds and seas of 6-9 ft are found south of the front to 24N and between 50W and 70W. Elsewhere west of 55W, moderate or weaker winds and moderate seas are prevalent. The rest of the tropical Atlantic are dominated by a broad subtropical ridge anchored by a 1032 mb high pressure system centered south of the Azores. The pressure gradient between this ridge and lower pressures in the deep tropics sustain fresh to locally strong N-NE winds and rough seas east of a line from 31N36W to the Lesser Antilles. The strongest winds and highest seas are found off Morocco. Elsewhere, moderate or weaker winds and moderate seas prevail. For the forecast west of 55W, the aforementioned low will move eastward along a stationary front past Bermuda through late Tue. Expect strong SW winds ahead of the low pressure and front Tue, with near gale to gale-force winds and rough to very rough seas expected southeast of Bermuda by late Tue. The front will stall from Bermuda to the northern Bahamas Tue night, ahead of a reinforcing front moving into the waters off northeast Florida accompanied by strong to near- gale force winds and rough seas. Looking ahead, winds and seas will diminish into Fri after the fronts merge, then weaken in place from Bermuda to the northern Bahamas with broad high pressure building off the Carolinas. Farther south, strong winds may pulse off the northern coast of Hispaniola Tue nigh. $$ Delgado
