Scattered showers are noted along the monsoon trough between 10W-20W. GULF OF MEXICO... A 1021 mb high pressure is centered over northern Florida and extends across the basin. Partly cloudy skies prevail with no significant convection. Moderate to locally fresh anticyclonic winds prevail across the basin. Surface ridging will dominate the Gulf waters through the weekend. The next cold front will reach the NW Gulf of Mexico on Sunday evening and extend from the Florida Big Bend through Tampico, Mexico by Mon afternoon. The front will then stall across the northern gulf waters through Tue morning. CARIBBEAN SEA... A stationary front extends across east-central Cuba and the NW Caribbean from 21N78W to a 1013 mb low near 19N82W. An upper- level trough axis extends from the Florida Peninsula to the NW Caribbean to Guatemala. Just east of the upper trough axis, upper-level diffluence is enhancing scattered moderate convection north of 18N between 78W-82W. Elsewhere, no significant convection is noted. Fresh to locally strong trades currently cover the eastern and central Caribbean mainly east of 75W. The weak low pressure area near 19N83W will dissipate tonight with a remnant trough prevailing through Fri. Moderate to fresh winds will dominate the central and eastern Caribbean waters through Sat night. Winds and seas will then increase in the southern Caribbean early on Sunday due to high pressure building north of the area. Near-gale force winds are expected along the coast of Colombia Sun night through Tue. ATLANTIC OCEAN... A cold front over the western Atlantic extends from 31N65W to a 1014 mb low near 26N74W.
