--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-05-26 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC260204_C_KWBC_20260526020431_49676782-3998-TWDEP.txt ****0000003739**** AXPZ20 KNHC 260204 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue May 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 0200 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 87W and N of 03N, moving west at 10 kt. Nearby convection is noted in the ITCZ/monsoon trough section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N84W to 08N102W. The ITCZ extends from 08N102W to 10N127W to 08N140W. Scattered moderate to isolated strong convection is noted from 03N to 10N east of 98W, and from 02N to 12N between 112W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak ridge extends from 30N135W through the Revillagigedo Islands. The pressure gradient between the ridge and a surface trough over the Gulf of California is supporting moderate to fresh winds across the waters west of Baja California. Gentle to moderate winds are south of Baja California and west of Cabo Corrientes. Light to gentle winds prevail elsewhere. Seas are in the 4-6 ft range over the open waters, and 1-3 ft in the Gulf of California. For the forecast, moderate to fresh winds will prevail offshore Baja California through the end of the week. A set of NW swell will move into the waters off Baja California Norte by midweek, supporting combined seas as high as 9 ft. Fresh SW to W gap winds will develop across the northern Gulf of California Tue and Wed. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh winds are found across the Gulf of Papagayo . Gentle to moderate winds prevail between Colombia and the Galapagos Islands. Light to gentle winds are elsewhere across the discussion waters. Seas are 5-7 ft in S swell between Colombia and the Galapagos Islands, and 4-6 ft elsewhere. For the forecast, fresh gap winds will pulse across the Papagayo region through Tue, with moderate winds thereafter. Gentle to moderate winds will prevail between Colombia and the Galapagos Islands. Light to gentle winds are expected elsewhere. Moderate seas will prevail through Thu. Large SW swell will enter the waters south of the Equator Fri, bringing rough seas to the waters between the Galapagos Islands and Colombia. ...REMAINDER OF THE AREA... A broad surface ridge extends across the waters north of 20N. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh NE trade winds north of the ITCZ to 20N and west of 110W, where seas are 6 to 8 ft. Gentle to moderate winds are elsewhere north of the ITCZ. Gentle to moderate SE winds are found south of the ITCZ. Seas over these waters are in the 5-7 ft range in mixed SW and N to NE swell. For the forecast, little change is expected in winds the next few days. Large NW to N swell generated by a deep low well N of the area will enter waters north of 27N by midweek, with wave heights in excess of 8 ft spreading as far south as 20N by Fri, then subsiding. The combination of wind waves developing from fresh to locally strong trades N of the ITCZ and W of 120W, and a mix of N and S swell, will bring rough seas over these waters. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC260803_C_KWBC_20260526080446_47448518-4125-TWDEP.txt ****0000003821**** AXPZ20 KNHC 260803 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Tue May 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.
