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. ...TROPICAL WAVES... A tropical wave extends its axis along 27W from 02N-13N. This wave is noted in model guidance at 700 mb and TPW imagery shows high moisture content associated with it. Scattered moderate convection is present south of 10N. A tropical wave extends its axis along 47W from 03N-13N. This wave is also noted in model guidance at 700 mb and TPW imagery shows high moisture content associated with it. Scattered showers are noted along the wave's axis. A tropical wave extends its axis along 64W from 05N-13N, moving west at around 10-15 kts. This wave is noted in model guidance at 700 mb. TPW imagery depicts moderate to high moisture content near and east of the wave axis. Scattered showers are noted south of 10N affecting Venezuela. ...MONSOON TROUGH/ITCZ... The monsoon trough is analyzed from 07N12W to 05N32W. The ITCZ extends from 05N32W to 06N44W. Aside from the showers related to the tropical waves, scattered showers are within 120 nm on the northern side of the monsoon trough between 19W-30W. GULF OF MEXICO... A cold front extends across the eastern portion of the basin from 29N83W to 19N93W. A surface ridge is building in the wake of the front across the western Gulf. Scattered showers are noted along and south of the front affecting the Yucatan Peninsula/Channel and the Florida Peninsula. The front will stall from southern Florida to the Yucatan Peninsula overnight, then gradually dissipate on Saturday as an easterly return flow develops across the basin. CARIBBEAN SEA... A broad area of high pressure centered over the west Atlantic extends across most of the basin. To the south, scattered moderate convection is observed over SW Caribbean south of 12N between 73W-84W, to the coast of Nicaragua. This convection is due to the eastern extent of the Eastern Pacific monsoon trough. The western Atlantic surface high will continue to shift eastward through the weekend and produce fresh tradewinds east of 80W, especially the south-central Caribbean through Saturday evening. These winds will be strongest at night close to the coast of Colombia. A Gulf of Mexico cold front will stall and weaken near the Yucatan Channel this morning. Trades will diminish by Sunday. ATLANTIC OCEAN... A western Atlantic 1031 mb high is centered near 36N48W. A stationary front enters the central Atlantic near 31N37W and extends to 20N48W to 19N63W. Scattered showers are within 130 nm on either side of the front mainly north of 20N between 42W-50W. An eastern Atlantic 1029 mb high is centered near 37N19W producing fair weather. The stationary front will dissipate this weekend. A cold front will enter the western Atlantic today enhancing convection across the western Atlantic. This front is expected to weaken and stall from near 31N74W to southern Florida this evening then gradually shift northward on Sunday.
