--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-06-26 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC260305_C_KWBC_20260626030659_32440682-3793-TWDEP.txt ****0000003923**** AXPZ20 KNHC 260305 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Fri Jun 26 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 0300 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 107W, south of 17N, moving westward at around 10 kt. Scattered moderate convection is active from 11N to 14N between 101W and 107W. The axis of a tropical wave is near 123W, south of 21N, moving westward at around 10 to 15 kt. No significant deep convection is occurring with this system this morning. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N84W to 06N95W to 11N118W to 08N125W. The ITCZ extends from 08N125W to beyond 06N140W. Scattered moderate to isolated strong convection is active from 06N to 08N between 87W and 95W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A Tehuantepec gap wind event is producing pulses of fresh to strong N to NE winds with seas 7-8 ft. A surface ridge extends from 27N120W southeastward to 20N110W. Winds elsewhere across the offshore waters are moderate or weaker. Seas on the Pacific waters are 5-6 ft in S to SW swell and are 1-3 ft over the Gulf of California waters. For the forecast, low pressure over the deep tropics will continue inducing fresh to strong N to NE gap winds across the Gulf of Tehuantepec through tomorrow night. Elsewhere, winds and seas across the Mexican offshore waters should be quiescent through early next week. Looking ahead, large NW swell may move into the waters off Baja California Norte starting Sun night. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A gap wind event is forcing fresh to strong NE winds across the Gulf of Papagayo region this evening with seas 7-9 ft. Elsewhere winds are moderate or weaker. Seas are 7-9 ft in S swell over the equatorial waters and 5-6 ft in SW swell over the remainder of the offshore waters. For the forecast, the pressure difference between high pressure north of the area and the monsoon trough farther south is supporting a Gulf of Papagayo region gap wind event. Fresh to strong NE to E winds should last through early next week. Elsewhere, winds should remain quiescent. Large S swell moving into the equatorial waters will continue through Sat night. ...REMAINDER OF THE AREA... A 1009 mb low is centered near 18N123W. Winds within 120 nm in the northwest semicircle are fresh to strong with seas 6-8 ft. Broad ridging dominates the area north of 15N. The moderate pressure gradient between the ridge and lower pressure over the monsoon trough/ITCZ is forcing moderate to fresh NE trades between 10N and the ridge. Elsewhere, winds across the open Pacific are moderate or weaker. Seas are 5-8 ft in mixed SW and N swell. For the forecast, the tropical wave near 107W is forecast to encounter more favorable conditions for development over the weekend across the central portion of the East Pacific basin. A tropical depression is likely to form by the early to middle part of next week while the wave moves westward to west-northwestward at 10 to 15 kt the waters well southwest of the Revillagigedo Islands. Outside of this system, little change in winds are expected for the next several days. A large SE swell should reach our southern border tonight and reach up to 01N with at least 8 ft seas for the next several days. $$ Christensen ########################### END OF MESSAGE SET ############################
