--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-04-23 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC230409_C_KWBC_20260423040948_49676782-1773-TWDEP.txt ****0000003618**** AXPZ20 KNHC 230409 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Thu Apr 23 2026 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 0000 UTC surface analysis and satellite imagery through 0350 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from near 07N78W to 05N90W to 05N102W. The ITCZ stretches from 05N103W to 05N118W then resumes west of a trough near 04N122W and beyond 04N140W. Scattered moderate convection is observed from 03S to 08N between 83W and 105W, and from 00N to 13N between 103W and 128W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A broad surface ridge prevails across the Baja offshores and extends to Cabo Corrientes. The pressure gradient between the ridge and a trough along the Gulf of California is supporting moderate to fresh NW winds across the Baja waters N of Cabo San Lazaro. Seas across these offshore waters are 7 to 8 ft in NW swell. Elsewhere, winds are mainly light to gentle and seas 4-6 ft in S swell. For the forecast, new high pressure well NW of the area will build modestly across the Baja waters through Thu, and act to increase winds modestly through early Fri before weakening Fri night through Sat. NW swell will continue to move across the Baja California waters and spread southeastward to the Revillagigedo Islands through Thu. Seas are expected to peak at 8-9 ft across the Baja waters tonight through Thu morning with this swell. Elsewhere, mostly light to gentle west to northwest winds are expected through Mon. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate NE to E gap winds and moderate seas to 5 ft are across the Papagayo region, extending downstream to 88W. Elsewhere, light to gentle variable winds prevail. Moderate seas in SW swell are slowly subsiding across the area waters through tonight. For the forecast, gap winds will remain moderate across the Papagayo region through Thu morning, then become light variable through Mon as southerly winds develop across the NW Caribbean. Otherwise, rather tranquil conditions are expected to continue over the Central American and the equatorial waters through early next week. The next significant SW swell is forecast to approach the Galapagos waters Sat, however seas are forecast to remain less than 8 ft. ...REMAINDER OF THE AREA... High pressure well NW of the area extends across the subtropical waters producing light to gentle anticyclonic winds N of 20N. Large NW swell behind a former front is supporting seas of 8-9 ft N of the ITCZ to 20N and W of 124W where moderate to locally fresh easterly trade winds prevail. Elsewhere, moderate or lighter winds and moderate seas are prevalent. For the forecast, modest high pressure N of the area will build weakly across the region over the next few days to maintain moderate to fresh trade winds S of 20N to the ITCZ and W of 120W. NW swell will spread southeastward over the next few days, leading to rough seas around 8 ft over the western tropical waters tonight through Thu night. Little overall changes are expected with winds and seas elsewhere through Mon. $$ Ramos ########################### END OF MESSAGE SET ############################
