--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-05-23 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC230200_C_KWBC_20260523020107_49676782-3783-TWDEP.txt ****0000004081**** AXPZ20 KNHC 230200 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sat May 23 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. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 07N110W to 11N120W to 07N133W. The ITCZ extends from 07N133W to beyond 07N140W. Scattered moderate and isolated strong convection is noted from 02N to 10N between 83W and 123W, and from 07N to 13N W of 130W. ...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 Sat, leading to moderate seas and moderate or weaker winds. Moderate to fresh westerly gap winds will develop during the evening and nighttime hours across the central and southern Gulf of California through early Sun. 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 locally 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... Gentle to moderate winds generally prevail across the discussion waters. Seas are 5-6 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 each night across the Papagayo region through early Sun, then increase to fresh to strong Sun night and Mon night. Otherwise, gentle to moderate winds and moderate seas in southerly swell will prevail into the weekend. 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 near 104W. The pressure gradient between high pressure ridge and lower pressure in the vicinity of the ITCZ and monsoon trough is supporting moderate to locally fresh NE trade winds N of the ITCZ to 20N, and west of 130W, where seas are 7 to 8 ft in N to NE swell. Mostly gentle to moderate winds are elsewhere N of the monsoon trough/ITCZ to 20N and W of 110W. Moderate winds are found S of 05N, 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 near 8 ft along the equator to 02N the W of 105W as SW swell continue to move into the area. For the forecast, the aforementioned ridge will gradually weaken while shifting southwestward through Sun. This will loosen the pressure gradient and allow winds and seas north of the ITCZ to decrease slightly to between gentle to moderate, with seas of 5 to 7 ft, respectively, by this weekend. Little change in winds is expected S of the ITCZ into the weekend. Large SW swell will continue to impact the southern waters through the weekend, as seas to around 8 ft occurring S of 05N will gradually shift eastward of 120W through early next week. $$ AL ########################### END OF MESSAGE SET ############################
