The followinginformation is based on satellite imagery, weather observations,radar, and meteorological analysis.Based on 1200 UTC surface analysis and satellite imagery through1500 UTC....TROPICAL WAVES...The axis of a tropical wave is near 87W north of 08N, moving west at around 10 kt. Scattered moderate and isolated strongconvection is noted from 04N-09N east of 90W.The axis of a tropical wave is near 106W north of 08N, moving westward at around 10 kt. Scattered moderate and isolated strongconvection is noted from 06N-16N between 100W-107W.The axis of a tropical wave is near 116W from 07N-17N, moving westward at around 10 kt. Scattered moderate and isolated strongconvection is noted from 07N-13N between 114W-120W.The axis of a tropical wave is near 127W from 04N-15N, moving westward at around 10 kt. Scattered moderate and isolated strongconvection is noted from 05N-13N between 120W-128W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...The monsoon trough extends from coastal Costa Rica near 10N86W to 10N110W. The ITCZ continues from 10N110W to 10N115W, from09N117W to 08N126W, and from 08N128W to beyond 06N140W. Scattered moderate and isolated strong convection is noted from 04N-09N east of 90W, from 06N-16N between 100W-107W, from 07N-13Nbetween 114W-120W, from 05N-13N between 120W-128W, and from 05N-11N west of 135W....OFFSHORE WATERS WITHIN 250 NM OF MEXICO...Fresh to locally strong N gap winds over the Gulf of Tehuantepecwith seas 6-7 ft. Fresh to strong SE winds over the N and central Gulf of California with seas 3-4 ft are occurring thismorning. Elsewhere winds are gentle to moderate with seas 4-6 ftin mixed swell.For the forecast, the fresh to locally strong N gap winds over the Gulf of Tehuantepec will diminish this evening. Low pressure over the SW United States will maintain fresh to strong SE winds over the N and central Gulf of California through Sat morning. Mainly gentle to moderate winds will prevail elsewhere through early next week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...Gentle to moderate NE to E winds are occurring north of themonsoon trough and gentle to moderate S to SW winds are foundsouth of the monsoon trough. Seas are 5-6 ft in S to SW swell.For the forecast, moderate to fresh E gap winds will continue across the Gulf of Papagayo region through Sat morning. Gentle tomoderate winds will prevail elsewhere over forecast waters. Elsewhere, light to gentle winds will prevail. Moderate SW swell currently impacting the equatorial zones should diminish on Sat....REMAINDER OF THE AREA...A 1033 mb high is centered at 39N141W with a surface ridgeextending to 30N127W to 20N110W. The moderate pressure gradientbetween the ridge and lower pressure over the ITCZ/monsoon troughis producing only moderate to locally fresh winds across forecastwaters. south of 02N and west of 100W, seas are 8-10 ft in SE toS swell. Elsewhere, seas are 5-7 ft in mixed swell.For the forecast, little change to winds and wind waves are expected for the next few days.
