--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-04-02 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC020151_C_KWBC_20260402015123_9109880-380-TWDEP.txt ****0000003406**** AXPZ20 KNHC 020151 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Thu Apr 2 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 0100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N78W to 07N89W. The ITCZ extends from 07N89W to 05N115W to 06N140W. A second ITCZ extends from 03.4S105W to beyond 03.4S120W. Scattered moderate convection is noted from 02N to 08N between 83W and 99W, and from 04N to 09N between 133W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure is starting to build SE toward northern waters, causing some fresh to locally strong NW winds offshore Cabo San Lucas and Cabo Corrientes. Otherwise mainly gentle to moderate winds prevail. Moderate seas prevail, except for slight seas in the Gulf of California. For the forecast, fresh winds will continue pulsing to locally strong near Cabo Corrientes and Cabo San Lucas tonight. Fresh to locally strong NW winds will dominate offshore Baja California Thu into Fri as high pressure builds W of the peninsula. Similar winds are likely to redevelop there Sun night and Mon. NW swell will bring locally rough seas off Baja California Norte Thu night through Sat. Looking ahead, strong N gap winds are forecast to develop in the Gulf of Tehuantepec Sun night. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh NE-E gap winds prevail over the Papagayo region. Winds are light to gentle elsewhere. Slight seas are offshore Colombia, with moderate seas elsewhere. For the forecast, fresh winds will pulse nightly in the Papagayo region through the period. Large S-SW swell spreading into the waters from offshore Ecuador to the Galapagos Islands will reach all area waters by Thu. This swell will build seas to rough from offshore Ecuador to the Galapagos Islands into Thu night. ...REMAINDER OF THE AREA... Broad high pressure prevails over the waters N of the ITCZ with gentle to moderate trades across the open waters, mainly light to gentle S of the ITCZ. Moderate seas prevail through the basin N of the Equator, with rough seas S of the Equator in S-SW swell. For the forecast, gentle to moderate winds will dominate the open waters through tonight as weak high pressure across much of the area slowly builds into the Baja California waters. A series of troughs will move into the NW waters and weaken W of 130W through rest of the week, leading to occasional fresh winds and possibly some locally rough seas. Large southerly swell will reach 10N Thu, then gradually subside. The pressure gradient will likely tighten N of 05N and W of 110W by the end of the week increasing trades to moderate to locally fresh, with seas building locally to rough as a result. Northerly swell will likely build seas to rough just S of 30N by late Thu night into the weekend. $$ Lewitsky
