The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2000 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal areas of Guinea near 09N13W to 06N19W. The ITCZ continues from 06N19W to 00N34W to the coast of Brazil near 02N43W. A trough is observed along the ITCZ from 07N24W to 01N24W. Another surface trough is to the north of the ITCZ from 09N37W to 01N38W. Isolated convection is seen 170 nm south of the monsoon trough east of 15W. Scattered moderate to isolated strong convection is near the ITCZ to the coast of Brazil from 01N-08S and west of 29W. GULF OF MEXICO... An upper level disturbance is inducing strong convection in the northwest Gulf from 29N-26N between 91W-94W. This cluster of storms could be producing severe weather along with frequent lightning and gusty winds. In the eastern Gulf, a weakening stationary front exits the Fort Myers, Florida coast near 26N82W to 25N86W with no significant weather associated with it. A trough is also observed in the Bay of Campeche from 23N94W to 19N94W. Smoke and haze are also seen on satellite in the Bay of Campeche due to ongoing agricultural fires in Mexico. Some stations in Mexico along the southern Bay of Campeche reporting visibility down to 4 nm. Light to gentle easterly winds are in the eastern basin, with gentle to moderate winds in the western Gulf. High pressure will prevail across the forecast waters through the remainder of the week and the weekend. A trough will develop each night over the Yucatan Peninsula, and support pulses of fresh to locally strong winds in the south central and southwest Gulf at night. CARIBBEAN SEA... Isolated thunderstorms are seen across the Greater Antilles and moving into their coastal waters with low-topped showers moving across the Lesser Antilles. Showers and thunderstorms are also moving off the coast of Costa Rica, Panama, and Colombia into the southwest Caribbean. Gentle to moderate trades are seen in the eastern Caribbean, with fresh to strong east-northeast winds north of Colombia. Moderate trades are seen in the Gulf of Honduras. Fresh to strong easterly winds will prevail in the south-central Caribbean and the Gulf of Honduras through mid week before diminishing. Smoke from ongoing agricultural fires across Central America will produce hazy skies and could reduce visibilities north of Honduras. ATLANTIC OCEAN... A cold front enters the central Atlantic near 31N62W and extends to the southwest in the western Atlantic near 28N76W. From 28N76W, the boundary stalls as it extends to West Palm Beach, Florida near 27N80W. Strong thunderstorms near this boundary are seen across South Florida and entering the Atlantic waters west of 79W. Showers are also seen along the cold front in the central Atlantic within 80 nm of the front. A pre-frontal trough is seen near 29N65W to eastern Cuba near 21N76W. Another surface trough is in the central Atlantic near 25N42W to near 20N52W with clouds seen along this trough but no significant weather. Two 1021 mb highs are seen near 25N50W and 26N31W.
