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 09N85W to 07N111W. The ITCZ extends from 07N111W to beyond 09N140W. Scattered moderate convection is noted from 04N to 08N between 80W and 85W, from 06N to 09N between 105W and 123W, and from 05N to 13N between 130W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to locally fresh winds are noted in the central and southern Gulf of California, with gentle to moderate winds across the remainder of the waters. Seas are in the 7-9 ft range west of the Baja California peninsula extending southward to near the Revillagigedo Islands. Elsewhere, seas are in the 4-6 ft range over the open waters off Mexico. In the Gulf of California, seas are in the 2-4 ft range. For the forecast, fresh to strong winds will return in the Gulf of Tehuantepec late Tue night 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. Large NW swell offshore the Baja California peninsula and southward to the Revillagigedo Islands will start to subside tonight. 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... Moderate to locally fresh 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 1027 mb high pressure centered N of the area near 36N129W 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 110W. NW swell is propagating across the discussion waters, with seas of 7-10 ft covering the waters north of 07N 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 slowly subside overnight into Tuesday, becoming confined to the trade wind belt just north of the ITCZ into mid-week. A new set of NW well 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. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC250831_C_KWBC_20251125083245_29294990-773-TWDEP.txt ****0000003948**** AXPZ20 KNHC 250831 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 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.

Strong high pressure building in the wake of the front will support fresh to strong gap winds and rough seas across the Gulf of Tehuantepec tonight and Wed. These winds will increase to gale force by early Thu as teh front moves through southern Mexico followed by cooler and drier air. A plume of fresh to strong N to NE gap winds and seas of 8 to 10 ft will reach into Pacific waters up to 500 nm downstream of the Gulf of Tehuantepec by late Thu. Winds and seas will diminish Fri and Sat as the high pressure north of the area shifts eastward. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 06N77W to 09N87W to 08N115W. The ITCZ extends from 08N115W to beyond 09N140W. Scattered moderate convection is observed from 07N to 09N between 110W and 130W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 1029 mb high pressure is centered near 36N129W. Recent scatterometer satellite passes indicated this pattern was supporting moderate to fresh NW winds over the Gulf of California, and moderate N to NE winds across the waters off Baja California. Recent 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. Fresh to strong winds will then persist in the Gulf of Tehuantepec into early Sat before diminishing. Farther north, moderate to fresh winds will pulse in the Gulf of California into mid- week, briefly strong at times, then diminishing Thu. Large NW swell off Baja California and the Revillagigedo Islands will subside this evening. Looking ahead, a weak cold front or trough will move into the waters off northern Baja California, supporting moderate to fresh westerly gap winds across the northern Gulf of California Sun night. ...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 95W. Light to gentle winds are elsewhere north of the monsoon trough. Gentle to moderate winds are found south 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 covering the area north of 15N and west of 115W is supporting moderate to fresh NE trade winds from 10N to 20N west of 115W. The trade winds are contributing to 8 to 10 ft combined seas in this area, along with a component of longer-period NW swell. NW swell of 8 to 9 ft lingers north of 20N and east of 120W toward the coast of Baja California. Gentle breezes and moderate seas in a mix of swell are noted elsewhere. The swell north of 20N and east of 120W will subside this evening. The fresh trade winds and the remaining 8 to 10 ft seas in the trade wind belt will gradually subside through late Wed as the high pressure north of the area weakens. Looking ahead, a new set of NW swell with rough seas may arrive by the end of the week and into next weekend north of 25N. Moderate winds and seas will persist elsewhere through Sun. $$ Christensen ########################### END OF MESSAGE SET ############################
