000 AXPZ20 KNHC 251556 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Mon Nov 25 2024 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 09N84W to 1011 mb low pressure near 09N116W to 11N140W. Scattered moderate convection is active from 09N to 11N between 103W and 105W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... An overnight scatterometer satellite pass confirmed fresh gap winds were still pulsing across the Gulf of Tehuantepec this morning. Elsewhere, 1020 mb high pressure centered off southern California is supporting gentle to moderate breezes and moderate combined seas primarily NW swell across open waters, with slight seas over the Gulf of California. For the forecast, a weak surface ridge west of the area extending to near the Revillagigedo Islands will remain in place throughout the week to support gentle to locally moderate NW to N winds across the Baja California offshore waters. Moderate N winds across the Tehuantepec area this morning will increase to strong to near gale-force tonight, Tue night, and then again Fri and Fri night with gale-force winds possible. Moderate S swell will move through the area waters from Cabo Corrientes eastward Mon night through Wed. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds, and seas of 3-5 ft, dominate N of the monsoon trough. S of the monsoon trough, gentle to moderate SW to W winds and seas of 3-5 ft prevail. For the forecast, moderate to occasionally fresh gap winds will prevail across the Papagayo region through Mon night then diminish. Otherwise, light to gentle winds are expected N of the monsoon trough. Gentle to moderate SW to W winds will prevail south of the monsoon trough, increasing briefly to moderate to fresh on Wed. Cross equatorial SW swell moving into the regional waters this morning will increase seas to 8 ft between Ecuador, Colombia and the Galapagos Islands through the middle of the week. The swell will propagate northward, increasing seas to 7 ft elsewhere Mon evening through Wed. ...REMAINDER OF THE AREA... Weak ridging extends across the waters north of 15N, anchored by 1020 mb high pressure off southern California, and south of a stalled frontal boundary extending east-to-west just north of the region to a 1006 mb low pressure centered near 31N144W.. Moderate to locally fresh SW winds are noted over the waters north of 25N and west of 135W, between the high pressure and the low pressure to the northwest. Seas are 7 to 8 ft in this area. The relatively weak ridge is supporting gentle to moderate breezes across the region. Combined seas are 6 to 9 ft primarily in southerly swell, and 4 to 6 ft elsewhere. For the forecast, the stationary front across the NW waters will meander along 30N-31N and west of 130W for the next few days, while low pressure forms along the front just NW of the area waters, and slowly drift eastward into the area late Wed through Fri. This will maintain moderate to fresh SW winds and seas around 8 ft across the waters north of 25N and west of 130W through late Tue. To the south, moderate to locally fresh trade winds will 1516N and east of 130W Mon through early Wed. $$ Christensen
