000 AXPZ20 KNHC 230744 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sun Jul 23 2023 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0710 UTC. ...TROPICAL WAVE... The axis of a tropical wave is near 86W/87W from central Honduras and western Nicaragua southward to across the Papagayo region, N of 04N, moving west around 15 to 20 kt. Nearby convection is described below. The axis of a tropical wave is near 102W/103W, N of 03N into SW Mexico, moving west at around 15 kt. Nearby convection is described below. The axis of a tropical wave is near 115W/116W, N of 04N, moving west around 15 kt. Nearby convection is described below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N75W to 10N86W to 08N110W. The ITCZ extends from 08N110W to 13N127W to beyond 09N140W. Scattered moderate isolated strong convection is evident from 01N to 10N between 77W and 86W, from 05N to 08N between 91W and 105W, and from 03N to 10N between 110W and 117W. Scattered moderate convection is evident from 11N to 14N between 96W and 100W, from 10N to 12N between 118W and 124W, from 05N to 08N between 122W and 126W, and from 09N to 11N between 136W and 139W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh N gap winds are in the immediate Gulf of Tehuantepec, with seas of 4-5 ft. Gentle to moderate winds are noted elsewhere across Mexican offshore waters, locally fresh near and just S of Punta Eugenia, with 3-5 ft seas over the open waters, and 1-3 ft seas in the Gulf of California. Deep convection that had developed over NW mainland Mexico has propagate offshore across the southern Gulf of California, with additional activity evident over the northern Gulf of California. For the forecast, expect moderate to fresh gap winds across the Gulf of Tehuantepec during the overnight hours through Mon, then fresh to strong thereafter. Gentle to moderate winds and moderate seas will persist elsewhere, except for locally gusty winds near clusters of showers and thunderstorms in portions of the Gulf of California during overnight hours. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Showers and thunderstorms have propagated from offshore Colombia and Panama westward to S of western Panama and Costa Rica, while diminishing somewhat over the past few hours. Moderate to fresh NE to E gap winds are likely over the Gulf of Papagayo. Moderate southerly winds are S of 03N, with seas of 4-6 ft in S-SW swell. Elsewhere, mainly light to gentle breezes and 3-4 ft seas are evident. For the forecast, fresh to strong gap winds will pulse across the Gulf of Papagayo each night through Thu night, with moderate to rough seas. Gentle to moderate winds and slight to moderate seas will persist elsewhere, except for locally gusty winds near clusters of showers and thunderstorms from Colombia to Costa Rica. ...REMAINDER OF THE AREA... The remnant 1011 mb low of T.D. Four-E remains exposed and void of conveciton, positioned near 16.5N132W. Recent ASCAT scatterometer data revealed fresh to locally strong winds within 210 nm in the N quadrant, with seas of 7-9 ft per a recent altimeter pass. Gentle to moderate winds and moderate seas prevail elsewhere, except fresh SE winds S of the Equator and W of 115W. For the forecast, the remnant low of Four-E will dissipate to a trough over the next 12 hours. Associated fresh winds and rough seas will diminish accordingly. Elsewhere, moderate to occasionally fresh winds can be expected N of the convergence zone and W of 130W, with gentle to moderate winds elsewhere through the middle part of the week. Moderate seas will prevail, building to around 8 ft S of the Equator and W of 95W Mon night through Wed. $$ Lewitsky
