--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-05-25 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC250200_C_KWBC_20260525020034_47448518-4027-TWDEP.txt ****0000003881**** AXPZ20 KNHC 250200 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon May 25 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 84W and N of 05N, drifting 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 07N95W. The ITCZ extends from 07N95W to 10N130W to beyond 07N140W. Scattered moderate to isolated strong convection is noted from 04N to 08N between 85W and 101W, and from 04N to 10N between 118W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure has started to build west of the region, tightening the pressure gradient slightly. With the tighter pressure gradient, moderate to fresh winds prevail 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, high pressure will build modestly across the region from the W through early this week. This will tighten the pressure gradient across the Baja waters, leading to moderate to fresh winds offshore Baja California through midweek, with a slight increase in seas. A set of NW swell will move into the waters off Baja California Norte midweek, bringing rough seas. 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... Moderate to fresh winds are in the Gulf of Papagayo. Gentle to moderate winds prevail between Colombia and the Galapagos Islands, as well as in the Gulf of Panama. 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 at night across the Papagayo region through Mon night. 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 southern waters 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 NE winds are elsewhere north of the ITCZ. Gentle to moderate SE winds are also found south of the ITCZ. Seas over these waters are in the 5-7 ft range in mixed SW and N to NE swell. Seas are reaching 8 ft primarily in southerly swell south of 03N between 90W and 100W. For the forecast, little change is expected in winds and seas the next few days. NW swell will enter waters north of 25N by midweek, bringing rough seas over these waters. Tradewinds will increase slightly over the western waters. The combination of wind waves developing from these trades, and NW swell will bring rough seas over these waters. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC250800_C_KWBC_20260525080125_49676782-3950-TWDEP.txt ****0000003743**** AXPZ20 KNHC 250800 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon May 25 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 ITCZ extends from 07N95W to 09.5N106W to 10N131W to beyond 07N140W.
