Scattered moderate to isolated strong convection is within 90 nm N and within 180 nm S of the ITCZ. Similar convection is noted south of the monsoon trough, from 02S to 05N between 10W and 18W. GULF OF MEXICO... The cold front that was over the eastern Gulf of Mexico earlier today has dissipated. A 1023 mb high pressure is centered over the central Gulf near 26N91W, with a ridge oriented north-south over the west-central Gulf. Fresh to locally strong NW winds are occurring over the eastern Gulf, where seas are 6 to 8 ft. Fresh to locally strong N winds are likely occurring along the NW coast of the Yucatan Peninsula, where seas are likely 4-5 ft. Moderate to fresh SE to S winds have developed along the immediate coast of Texas and NE Mexico, where seas are 3-4 ft. Seas are 1 to 3 ft in the area of the high pressure ridge. For the forecast, the fresh winds over the eastern Gulf will shift east of the Gulf tonight. Fresh to strong east to southeast return flow is expected to develop in the western Gulf tonight and continue through Wed afternoon. A weak cold front may move into the northern Gulf Thu and stall. CARIBBEAN SEA... A stationary front extends from eastern Cuba near 21N77W to northern Honduras near 16N87W. Isolated showers are possible near the front. Fresh to strong N to NE winds are within 120 nm N of the front, over the NW Caribbean. The winds are allowing for 6 to 8 ft seas over portions of the Gulf of Honduras and NW Caribbean. Elsewhere, fresh to strong winds are likely occurring within 120 nm offshore Colombia and in the Gulf of Venezuela. Mainly moderate trades prevail elsewhere. Seas are 6-8 ft offshore Colombia and 4-6 ft elsewhere. For the forecast, fresh to strong northeast to east trade winds will pulse tonight in the south-central Caribbean near the coast of Colombia and in the Gulf of Venezuela. These winds will persist through Thu night. The stationary front will gradually weaken and dissipate by early Sun evening. Winds will diminish to moderate to fresh speeds tonight. High pressure building in behind the front will then increase northeast to east winds across the lee of Cuba and Windward Passage areas from Sun night through at least Tue night. Fresh to strong east to southeast winds will pulse in the Gulf of Honduras at night from Tue through Thu. ATLANTIC OCEAN... A cold front extends from 31N69W to the central Bahamas near 23N75W to eastern Cuba near 21N77W. A secondary reinforcing cold front extends from 31N73W to 28N76W to Ft. Lauderdale, Florida, mentioned above in the special features section. Scattered showers are along and within 90 nm east of the leading cold front, mainly north of 27N. Fresh to strong southwest winds are within 180 nm ahead of the leading front, mainly north of 28N. Strong to near gale force W winds are occurring to the west of the second cold front, mainly north of 28N. A recent altimeter pass indicates that seas have already built up to at least 12 ft in the area of strong to near gale force W winds. Farther east, a 1023 mb high pressure is near 33N49W. A cold front extends from 31N27W to 28N32W to 28N44W. Fresh winds prevail on both sides of the cold front, mainly north of 29N between 21W-32W. Seas are 8-10 ft north of 29N between 23W-45W. A surface trough is analyzed from 28N44W to 26N48W to 26N52W. Winds are moderate or weaker near the surface trough. Moderate to fresh trades prevail across the tropical Atlantic. Seas are 6-9 ft in the tropical trade wind area. Gentle winds and 4-6 ft seas prevail across much of area from 21N-27N between 35W-57W. For the forecast west of 55W, the leading cold front will reach from near 31N64W to 25N70W to the Windward Passage Sun morning. Strong winds are expected to continue ahead and behind this front through Sun. The second cold front will be followed by strong to gale-force winds and building seas through Sun as it merges with the first front on Sun morning. High pressure will build over the area early next week, which will improve conditions over most of the forecast waters. This high pressure will lead to increasing northeast to east winds near the Windward Passage from Mon night through Thu night as the high center slides eastward along 30N/31N. $$ Hagen
