707 AXPZ20 KNHC 241926 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Mon Nov 24 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 1800 UTC surface analysis and satellite imagery through 1900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 07N77W to 07N112W. The ITCZ extends from 07N112W to 09.5N135W to beyond 07N140W. Scattered moderate convection is noted from 03N to 09N between 77W and 93W, from 06.5N to 10N between 105W and 110W, from 12N to 15N between 113W and 121W, from 07.5N to 10N between 117.5W and 122W, and from 06N to 10N between 132W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends from N of the area near 37N129W through 30N124W to near the Revillagigedo Islands. Recent ASCAT scatterometer data showed that winds have diminished to moderate to fresh in both the Gulf of Tehuantepec and near Cabo Corrientes as the pressure gradient at both locations has weakened slightly. 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 7-10 ft range west of the Baja California peninsula extending southward to near the Revillagigedo Islands. Seas of 5-7 ft are over the Gulf of Tehuantepec, as well as off Cabo Corrientes. Elsewhere, seas are in the 4-6 ft range over the open waters off Mexico. In the Gulf of California, seas are 3 ft or less, except higher near the entrance. For the forecast, fresh to strong winds in the Gulf of Tehuantepec will return 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... Fresh NE winds are over the Papagayo region. Gentle to moderate winds are found elsewhere. Seas are in the 3-5 ft range, except to 6 ft near the Gulf of Papagayo. Active convection is present offshore northern Colombia and Panama as described above with locally higher winds and seas possible. 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 N of the area near 37N129W through 30N124W 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 as indicated by recent ASCAT scatterometer data. NW swell is propagating across the discussion waters, with rough seas in excess of 8 ft covering the waters north of 06N and west of 108W. 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 start to slowly subside early this week, 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. $$ Lewitsky
