The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...TROPICAL WAVES... A tropical wave is along 85W, N of 07N to across Central America, moving W at 10-15 kt. Any significant convection is located to the E over Central American and the western Caribbean Sea. A tropical wave is along 100W, N of 04N to the coast of SW Mexico, moving W around 15 kt. Scattered moderate and isolated strong convection is noted from 09N to 13N between 97W and 103W. A tropical wave is along 130W, from 02N to 15N, moving W at 15-20 kt. Scattered moderate convection is noted from 05N to 07N between 130W and 132W, and also from 08N to 12N between 127W and 131W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from near the Panama/Colombia border at 09N77W to 08N90W to 10N100W to 08N110W to 10N127W. The intertropical convergence zone axis extends from 06N132W to 07N140W. Scattered moderate and isolated strong convection is from 06N to 09N between 78W and 82W, from 09N to 11N between 87W and 91W, within 180 nm SW of the axis between 88W and 98W, from 09N to 11N between 95W and 97W, and from 07N to 09N between 104W and 108W. Scattered moderate convection is from 05N to 10N between 108W and 119W, from 08N to 11N between 120W and 127W, and also from 05N to 07N between 133W and 137W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The remnant 1011 mb low pressure area of Ivo is located near 24N116W, with no significant convection. This low should completely dissipate during the next 24-48 hours while remaining nearly stationary. Winds in the Gulf of Tehuantepec will become northerly at fresh to strong Wed night through early Fri, with moderate to fresh pulses at night thereafter. High pressure ridging will prevail elsewhere along the outer offshore waters boundary, with mainly gentle to moderate NW to N winds. Gentle to moderate southerly winds in the Gulf of California will increase to fresh to strong near the entrance late tonight into early Wed, with similar conditions in the northern Gulf Wed night into early Thu, then again Sat night into early Sun. No significant swell events are anticipated through the remainder of the week and the upcoming weekend. Offshore WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh NE to E winds in the Gulf of Papagayo will pulse to fresh to strong tonight into early Wed, then again Wed night into early Thu, with weaker winds thereafter. Light to gentle winds are expected elsewhere N of the monsoon trough, with gentle to moderate S to SW winds S of the monsoon trough. No significant southerly swells are anticipated through the remainder of the week and the upcoming weekend. REMAINDER OF THE AREA... Weak and broad high pressure is centered near 25N135W with ridging extending to the SE to near 16N112W. Recent scatterometer data showed mainly gentle anticyclonic winds around the high, N of the ITCZ/monsoon trough, locally moderate. Recent altimeter data showed seas of 4-6 ft N of the ITCZ/monsoon trough, with 4-7 ft seas with some cross-equatorial southerly swell S of the ITCZ/monsoon trough. The high is forecast to linger through the end of the week while strengthening slightly to 1022 mb by Fri afternoon, then weakening again this weekend. Little change in marine conditions is expected through this time period. $$ Lewitsky
