The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1550 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of Guinea-Bissau near 12N16W to 03N23W. The ITCZ continues from 03N23W to 01S45W. Scattered moderate convection is observed south of 06N and east of 18W, and from 01N to 04N between 32W and 50W. GULF OF MEXICO... A weak cold front has entered the far northern Gulf waters, extending from the Florida Panhandle, across the Mississippi River Delta, to near Houston, Texas. Otherwise, high pressure centered north of the Yucatan Peninsula, near 24N88W, is causing gentle to moderate anticyclonic winds across the majority of the basin. The exception is in the western Gulf near the Texas- Mexico border, where southerly winds have increased to a fresh breeze. Seas are generally 2-4 ft across the basin, with 3-5 ft associated with the fresh winds in the western Gulf, and 4-6 ft swell in the SE Gulf, on an abating trend. For the forecast, high pressure will build across the area and become centered over the eastern Gulf through Wed. Fresh winds will pulse across the Bay of Campeche each night during the forecast period. CARIBBEAN SEA... A stationary front extends across the NW Caribbean, from 21N79W to 17N85W. A few showers and thunderstorms are observed near the boundary. West of the front, winds are moderate from the NE. East of the front in the NW Caribbean, winds are light and variable. A moderate to fresh easterly breeze dominates the remainder of the basin. Seas are 4-6 ft across the majority of the basin, with 2-4 ft near the light winds ahead of the stationary boundary. For the forecast, a stationary front over the NW Caribbean will begin to weaken this afternoon and dissipate by early Tue. Fresh to strong winds will develop offshore Colombia tonight and continue through the rest of the week. ATLANTIC OCEAN... A cold front extends from 31N68.5W, across the Bahamas, to 22N78W. Scattered moderate with isolated strong convection is observed up to 180 nm ahead of the front. Fresh to strong SW winds are observed ahead of the front, with moderate to fresh westerly winds behind the front. Seas are 6-10 ft in the western Atlantic, increasing with latitude. 1022 mb high pressure centered near 30N51W dominates the central subtropical Atlantic. Winds are light near the high surrounded by moderate anticyclonic flow. Farther east, a stationary boundary extends from 31N27W to 21N45W. Scattered moderate convection is observed from 22N to 31N, between 25W and 34W. Moderate westerly winds are west of the front with gentle to moderate SW winds east of the boundary. Moderate trade winds dominate the remainder of the basin. 7-10 ft seas in northerly swell are observed north of 27N, between 23W and 59W. Otherwise, seas are generally 5-7 ft across the central and eastern Atlantic. For the forecast W of 55W, a cold front extends from near 31N69W to east-central Cuba. Fresh to strong winds will prevail in the vicinity of the front to the N of 28N today. The front will gradually weaken and dissipate on Tue as it approaches the eastern part of the area. The next front, weaker in intensity, will move across the northern waters by mid-week. $$ Flynn
