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 81W and N of 05N, moving W at 10 kt. Nearby convection is noted in the ITCZ/monsoon trough section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N84W to 08N91W. The ITCZ extends from 08N91W to 10N125W to beyond 07N140W. Scattered moderate convection is noted from 02N to 08N and E of 95W. Scattered moderate and isolated strong convection is noted from 02N to 10N between 108W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak pressure gradient prevails across the discussion waters. Gentle to moderate winds generally prevail across the area, except light to gentle south of southern Mexico. Seas are in the 4-6 ft range over the open waters, and 2-3 ft over the Gulf of California. For the forecast, a weak pressure gradient will dominate the regional waters through tonight, leading to moderate seas and moderate or weaker winds. Moderate to fresh westerly gap winds will develop across the central and southern Gulf of California tonight. High pressure will build modestly across the region from the W Sun through early next week. This will tighten the pressure gradient across the Baja waters by Sun afternoon, leading to moderate to fresh winds offshore Baja California through Tue, with a slight increase in seas. Seas offshore of Baja are expected to build to near 8 ft by Mon night. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to locally strong winds are over 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 4-6 ft in S swell between Colombia and the Galapagos Islands, and 4-5 ft elsewhere. For the forecast, moderate gap winds will pulse to fresh at night across the Papagayo region through Mon night. Gentle to moderate winds will prevail between Colombia and the Galapagos Islands through the weekend. Light to gentle winds are expected elsewhere. Fresh SW swell will move into the Galapagos area waters this weekend, with seas building to near 8 ft on Sun. Expect periods of active convection S of 10N and E of 90W through the weekend. ...REMAINDER OF THE AREA... A broad surface ridge extends southeastward from high pressure centered well N of the Hawaiian Islands, through the Revillagigedo Islands to 105W. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to locally fresh NE trade winds N of the ITCZ to 20N, and west of 110W, where seas are 6 to 7 ft. Gentle to moderate winds are elsewhere N of the ITCZ. Moderate winds are found S of 04N, with light to gentle winds elsewhere over the discussion waters. Seas over these waters are in the 5-7 ft range in mixed SW and N to NE swell. Seas are reaching 8 ft south of 05N and W of 100W as SW swell continues to move into the area. For the forecast, the aforementioned ridge will gradually weaken while shifting southwestward through the weekend. This will loosen the pressure gradient and allow winds and seas north of the ITCZ to decrease slightly to gentle to moderate, with seas of 5 to 7 ft. Little change in wind is expected S of the ITCZ through the weekend. Rough seas in SW swell will impact the southern waters through the weekend. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC240801_C_KWBC_20260524080217_49676782-3871-TWDEP.txt ****0000003629**** AXPZ20 KNHC 240801 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sun May 24 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.
