The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0500 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coast of Africa near 12N17W to 03N24W to 01N33W. The ITCZ continues from that point to the coast of Brazil near 02S44W. Scattered moderate convection is along and south of the monsoon trough mainly east of 33W. GULF OF MEXICO... A stationary front extends across the basin from 27N83W to 25N95W. Scattered moderate convection is noted across the eastern half of the basin mainly east of 90W, with strongest activity over the Straits of Florida affecting northern Cuba also. A pair of surface troughs are analyzed over the western Gulf. The first extends from 23N88W to 20N90W, while the second trough is from 24N93W to 21N94W. Smoke is still noted on satellite imagery over the western Gulf mainly west of 90W. The stationary front will weaken tonight through Wed night. High pressure will then build over the northern Gulf Thu through Fri, then move east Fri night through Sun to support increasing southeast return flow. Smoke and haze from ongoing wildfires in Mexico will reduce visibilities over the western Gulf and the Bay of Campeche over the next several days. CARIBBEAN SEA... A broad upper level ridge prevails across most of the basin inducing strong subsidence across most of the area. Scatterometer data depicts fresh to strong trades over the central and western Caribbean, while moderate trade winds prevail over the eastern Caribbean. Fresh to strong winds will persist across the south central Caribbean through Wed night, then diminish as a high pressure ridge lifts northeast and moves away from the region. Strongest winds will prevail along the coasts of Venezuela and Colombia. Fresh to strong winds will prevail over the Gulf of Honduras region through the weekend. Smoke and haze from ongoing fires in Central America will reduce visibilities north of Honduras over the next several days. ATLANTIC OCEAN... A cold front enters the western Atlantic waters near 32N69W to the Florida coast near 28N80W. Scattered showers prevail over the west Atlantic in the vicinity of the front mainly west of 70W. To the east, a line of moderate convection prevails north of 25N between 59W-65W. Surface ridging prevails across the remainder of the basin anchored by a 1027 mb high centered near 31N40W. The cold front will continue moving across the west Atlantic tonight and Wed, then stall and weaken over the central waters Wed night and Thu.
