Based on 1200 UTC surface analysis and satellite imagery through 1700 UTC. ...TROPICAL WAVES... A tropical wave is along 36W from 13N southward moving W at 10 knots. Isolated moderate convection is from 01N-07N between 32W-40W. A tropical wave is along 54W from 13N southward moving W at 10 knots. Scattered moderate convection is from 09N-12N between 52W-55W. A tropical wave is along 68W from 17N southward moving W at 10 knots. Scattered moderate to strong convection is S of 15N between 64W-72W. A tropical wave is along 87W from 18N southward, extending into Honduras, moving W at 5 10 knots. No significant convection is apparent in the Caribbean or Central America. ...MONSOON TROUGH/ITCZ... The monsoon trough extends off the coast of Sierra Leone near 07N13W to 07N17W. The ITCZ continues from 07N17W to 06N30W to 03N35W. The ITCZ continues W of a tropical wave from 03N38W to the coast of N Brazil near 00N50W. Besides the convection mentioned in the tropical wave section, isolated moderate convection is from 04N-10N between 10W-20W. Scattered moderate convection is also from 04N-07N between 42W-47W. GULF OF MEXICO... A cold front is over the NW Gulf of Mexico from S Louisiana near 29N92W to S Texas near 26N98W. Isolated moderate convection is within 90 nm of the front to include SE Louisiana and S Mississippi. Elsewhere, radar imagery shows isolated showers over the Florida Peninsula. Weak high pressure across the NW Bahamas extends westward to the central Gulf and will maintain moderate to fresh southerly winds, highest in the western Gulf S of the front. The NW Gulf front will reach a line from Florida Panhandle to the SW Gulf Thu night, then stall and gradually dissipate from the Florida Big Bend to western Bay of Campeche late Fri through Sat. CARIBBEAN SEA... Two tropical waves waves are in the Caribbean. See above. The eastern extent of the E Pacific monsoon trough is producing scattered moderate to isolated strong convection over the SW Caribbean to include Costa Rica, Panama, N Colombia, and W Venezuela. Elsewhere, scattered showers are over the Windward Islands. Similar showers are over central and eastern Cuba. Generally moderate trade winds will prevail across most of the basin through Sat as weak high pressure prevails across the W Atlantic. A pulse of fresh to locally strong winds is expected in the Gulf of Honduras tonight. A tropical wave in the western Caribbean will move into Central America later today. A weak tropical wave will pass south of Hispaniola today then south of Jamaica Thu night. Fresh to strong trade winds will return to east and central portions of the basin Sat night through Mon as high pressure builds across the W Atlantic. ATLANTIC OCEAN... A 1014 mb low is over the W Atlantic near near 35N52W. A cold front curves away from the low pressure center to 31N50W to 23N60W to 22N70W to 29N79W. Scattered moderate convection is within 60 nm of the front. Surface ridging is over the E Atlantic N of 20N and E of 45W. The W Atlantic low will remain nearly stationary and weaken through the end of the week. The cold front will sag into the Bahamas and Turks and Caicos today, then stall tonight just north of the Greater Antilles, where it will gradually dissipate into the weekend. High pressure will build in behind the front and be the dominant weather feature into the weekend. $$ Formosa
