The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0830 UTC. ...SPECIAL FEATURES... Caribbean Gale Warning: High pressure N of the area combined with the Colombian low will support gale force winds off the coast of Colombia through the early morning hours today before diminishing. Please refer to the latest NWS High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from 07N12W to 01N23W. The ITCZ continues from 01N23W to 00N50W. Scattered moderate convection is noted from 06S to 02N between 10W and 34W. GULF OF AMERICA... A 1019 mb low pressure area is centered offshore southern Texas near 26N95W. A stationary front extends from the low to the Bay of Campeche, with a warm front from the low to 28N89W. Scattered showers and isolated thunderstorms are N of the warm front. Moderate to fresh winds are near the low center. Gentle to moderate winds prevail elsewhere, except for fresh winds over the SW Gulf. Seas are in the 7-8 ft range W of the low, and 4-7 ft elsewhere except the NE Gulf where seas of 2-4 ft prevail. For the forecast, the low will track NE through early tonight, then quickly E to SE toward southern Florida on Mon with the cold front trailing from the low as it moves across the basin. Fresh to strong winds are expected around the low pressure while moderate to fresh winds are expected behind the boundary. Weak high pressure will settle over the central waters Tue through Wed night in its wake with tranquil marine conditions across the basin. Another cold front may sweep across the basin Thu and Thu night. CARIBBEAN SEA... A Gale Warning is in effect off the coast of Colombia. Please, refer to the Special Features section above for more details. Outside of the gale warning area, fresh to strong NE winds are in the lee of Cuba, with fresh winds in the Windward Passage as well as over the south-central Caribbean. Moderate to locally fresh trade winds and moderate seas prevail elsewhere. Seas of 8-10 ft are in the south central Caribbean, and 4-6 ft elsewhere. For the forecast, moderate to locally fresh winds in the western Caribbean will diminish early in the week as a cold front slips SE of the Yucatan Channel. The front will reach from western Cuba to the Gulf of Honduras late Mon night with fresh winds behind it. The front will stall and dissipate from eastern Cuba to eastern Honduras by early Wed. Fresh to near gale-force winds offshore northern Colombia will diminish gradually through Tue, then strengthen again toward the end of the week. Mainly moderate to locally fresh winds will prevail elsewhere in the central and eastern Caribbean through the middle of the week, and in the Tropical N Atlantic where moderate to locally rough seas will prevail. ATLANTIC OCEAN... A cold front extends from near 31N44W southwestward to 23N60W where it becomes stationary front across the Turks and Caicos Islands and eastern Cuba. Fresh winds are S of 23N and W of the front, with gentle to moderate winds elsewhere S of 24N and within 90 nm W of the front. Light to gentle winds are elsewhere W of the front. Seas of 8-12 ft prevail W of the front to near 70W, with seas of 5-7 ft W of 70W. A ridge extends from a 1030 mb high near 36N13W SW to near 26N46W. Light to gentle winds are noted along the ridge axis. Moderate to fresh winds prevail elsewhere. E of the front, mainly 6-9 ft seas prevail, reaching 10 ft just west of the cabo Verde Islands. For the forecast west of 55W, the front will dissipate today. Rough to very rough seas behind the front will subside across the waters W of 55W by late tonight. Broad low pressure from the Gulf of America will approach South Florida Mon, and track NE to N 31N by late Tue night dragging a trailing cold front across the western part of the area. Fresh to strong southerly winds will prevail ahead of the front and low Tue through Wed. By late Wed night, marine conditions may improve under a weak pressure pattern. Another front may move offshore the SE United States Thu night. $$ AL
