    000AXPZ20 KNHC 141459TWDEP Tropical Weather DiscussionNWS National Hurricane Center Miami FL1605 UTC Sat Mar 14 2026Tropical Weather Discussion for the eastern Pacific Ocean from03.4S to 30N, east of 120W including the Gulf of California, andfrom the Equator to 30N, between 120W and 140W. The followinginformation is based on satellite imagery, weather observations,radar, and meteorological analysis.Based on 1200 UTC surface analysis and satellite imagery through1450 UTC....INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...A surface trough extends from 08N78W to 03N95W. The ITCZ extendsfrom 03N95W to 00N110W to beyond 03N140W. Scattered moderate convection is noted from 02N to 04N between 85W and 95W, and from03N to 05N between 125W and 130W....OFFSHORE WATERS WITHIN 250 NM OF MEXICO...Moderate NW to N winds are noted off Cabo Corrientes, but lightto gentle breezes dominate elsewhere across Mexican offshorewaters. Seas are 4-6 ft in NW swell, except 1-3 ft in the Gulf ofCalifornia. For the forecast, large NW swell will move into the outer offshore waters off Baja California Norte through late Sun, then subside. Elsewhere, a weak pressure pattern over the region will maintain gentle to moderate breezes and and moderate seas over the open waters off Mexico, with slight to moderate seas in the Gulf of California into next week. Looking ahead, a cold front moving into southern Mexico will support gale force gap winds across the Tehuantepec region starting Mon night and persisting into mid week. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...Fresh to strong winds are over and downwind the Gulf of Papagayo. Moderate to locally strong winds are over the Gulf of Panama. Elsewhere, light to gentle winds prevail. Rough seas inSW swell has entered the waters SW of the Galapagos Islands. Seas are in the 4-7 ft range elsewhere across the discussion waters.For the forecast, fresh to occasionally strong gap winds will pulse to strong across the Papagayo region through Sun. Moderate N winds will pulse to fresh in the Gulf of Panama through Sun. Mainly light to gentle winds will prevail elsewhere through the forecast period. Cross- equatorial SW swell will bring rough seasto the waters between the Galapagos Islands and Ecuador tonight through Sat night....REMAINDER OF THE AREA...High pressure is centered north of the area. The pressure gradient between this area of high pressure and lower pressure inthe vicinity of the ITCZ is supporting moderate winds north of the ITCZ to near 15N and west of 110W. Moderate to locally roughseas in NE to E swell cover much of these waters. SW swell hascrossed the equator bringing rough seas S of 06N between 90W and115W. Elsewhere, moderate or weaker winds and moderate seas prevail.For the forecast, winds will gradually diminish across the discussion waters through early next week. The rough seas in thetradewind zone will subside today. Cross-equatorial SW swell will bring rough seas over the waters S of 10N and E of 120W tonight before subsiding through Sun.$$Christensen
