706 AXPZ20 KNHC 251517 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Tue Nov 25 2025 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 06N78W to 09N90W to 07N115W. The ITCZ extends from 07N115W to beyond 09N140W. Scattered moderate convection is noted within 90 nm of the monsoon trough and ITCZ between 78W and 83W, between 105W and 115W, and between 120W and 135W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 1026 mb high pressure is centered near 35N128W. Overnight scatterometer satellite passes indicated this pattern was supporting moderate N to NE winds across the waters of Baja California. Concurrent altimeter satellite passes showed combined seas to 9 ft, primarily in NW swell. The scatterometer also confirmed moderate to fresh winds in the Gulf of California and off Cabo Corrientes. Light to gentle breezes are noted elsewhere. Seas are 5 to 7 ft elsewhere over open waters, and 3 to 5 ft in the Gulf of California. For the forecast, fresh to strong winds will return in the Gulf of Tehuantepec late tonight into early Wed, possibly increasing to gale-force Thu morning through Fri morning leading to rough seas. Winds may briefly diminish below gale- force Thu afternoon. Fresh to strong winds will then persist in the Gulf of Tehuantepec into early Sat before diminishing. Moderate to fresh winds will pulse in the Gulf of California into mid-week, briefly strong at times, with fresh to strong winds possible in the northern Gulf this weekend as a cold front approaches. Rough seas in large NW swell offshore the Baja California peninsula and southward to the Revillagigedo Islands will subside today. New NW swell associated with the cold front may arrive offshore Baja California next weekend. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to locally strong NE winds are over the Papagayo region, with moderate winds extending downstream to near 92W. Light to gentle winds are elsewhere N of the monsoon trough. Gentle to moderate winds are found S of the monsoon trough. Seas are in the 3-5 ft range For the forecast, moderate to fresh NE winds will pulse over and downstream of the Papagayo region this week and into next weekend, locally strong at times. Moderate or lighter winds are forecast elsewhere through the week and into next weekend. No significant swells are forecast this week. ...REMAINDER OF THE AREA... A ridge extends from a 1026 mb high pressure centered N of the area near 35N128W to near the Revillagigedo Islands. The pressure gradient between the ridging and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh winds north of the ITCZ to around 20N and west of 115W. NW swell is propagating across the discussion waters, with seas of 7-10 ft covering the waters north of 08N and west of 110W. Mainly moderate winds and seas of 4-7 ft in predominantly NW swell prevail over the remainder of the discussion waters. The rough seas of 8 ft or greater will subside today, becoming confined to the trade wind belt just north of the ITCZ into mid- week. A new set of NW swell with rough seas may arrive by the end of the week and into next weekend. Moderate to fresh trades will continue over the waters north of the ITCZ to near 20N and west of 110W through at least the middle of the week. $$ Christensen
