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.

A weak ridge extends from near 30N135W to the vicinity of the Revillagigedo Islands. The pressure gradient between the ridge and a surface trough over the Gulf of California is supporting moderate to fresh winds over the waters west of Baja California.

Fresh to strong S to SW gap winds will develop in the northern Gulf of California starting tonight, diminish Wed afternoon, then start up again late Wed night and diminish early on Thu. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... The early fresh northeast to east winds in the Gulf of Papagayo region have diminish to mostly gentle speeds. Seas there are 4-6 ft. Gentle to moderate winds prevail between Colombia and the Galapagos Islands, and light to gentle winds are elsewhere across the discussion waters. Seas are 5-7 ft in S to SW swell between Colombia and the Galapagos Islands, and 4-6 ft elsewhere. An area of numerous showers and thunderstorms is present from 04N to 10N between 82W-87W. For the forecast, rather tranquil marine conditions are expected overall through the period as winds will mostly be in the light to gentle range. 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. The swell will slowly subside during the weekend. ...REMAINDER OF THE AREA... High pressure covers the waters north of 20N as a surface trough is analyzed from near 15N134W to 10N140W, and a cold front has recently pushed south to the far northern waters along a position from near 30N130W to 29N140W. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the monsoon trough is generally supporting moderate to fresh NE trade winds north of the trough to near 20N and west of about 115W. The most concentration of the fresh winds is NW of the surface trough to near 23N, and also north of the cold front as indicated by recent Ascat satellite data passes. Wave heights over these waters, and those behind the cold front are in the range of 6-9 ft in NW to N swell. Gentle to moderate SE winds are found south of the ITCZ. Wave heights over these waters are in the 5-7 ft range in N to NE swell mixed with SW swell. For the forecast, little change is expected in winds the next few days. The aforementioned cold front will press southward while weakening through Wed night and eventually dissipate across the central waters late Wed night, or on Thu. The swell in the wake of the frontal boundary will propagate through the waters N of 25N by Wed night, with wave heights of 8 to 9 ft reaching as far south as about 14N by late Thu. The combination of the swell with wind generated waves produced by the fresh trade winds N of the monsoon trough is expected to induce rough seas over a good portion of these waters by late Thu. $$ Aguirre ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC262355CCA_C_KWBC_20260526235551_47448518-4176-TWDEP.txt ****0000005300**** AXPZ20 KNHC 262355 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 2205 UTC Tue May 26 2026 Corrected Remainder of the Area section 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.
