000 AXPZ20 KNHC 270252 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sun Nov 27 2022 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 0210 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 11N74W to 10.5N110W to 08.5N140W. Scattered moderate to strong convection is noted from 07N to 14N between 89.5W and 129W, and from 07.5N to 10N W of 135W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to locally fresh N winds are dominating waters from Cabo Corrientes northward, due to weakening high pressure in the Great Basin. This also includes the south half of the Gulf of California. To the south, mainly gentle NW to W winds prevail. Seas from Cabo Corrientes northward are 5 to 7 ft, except to 8 ft across the outer offshore waters of central and northern Baja California. Seas are generally 3 to 5 ft across the south half of the Gulf of California, and 4 to 5 ft south of Cabo Corrientes. For the forecast, high pressure centered over the Great Basin will gradually weaken and slide east this weekend, allowing winds in the Gulf of California and adjacent waters to diminish. Fresh SW winds will develop in the northern Gulf of California Mon, to the N and E of a low pressure passing N of the area, then increase to strong Mon night to Tue. Looking ahead, strong gap winds are likely in the Tehuantepec region starting Wed night and are expected to increase to gale force Thu morning. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle variable winds and seas of 3 to 5 ft dominate areas N of monsoon trough, along about 10N, with mainly moderate S to SW winds and 4 to 6 ft seas to the S. For the forecast, gentle to moderate winds and seas will persist across the region into early next week as a weak pressure pattern prevails. Fresh gap winds will develop and pulse to strong each night across the Gulf of Papagayo region Mon night into Thu. REMAINDER OF THE AREA... A 1002 mb low pressure system is centered west of the area near 30.5N147.5W. A stationary front to the east of the low extends N to S along 139W from 27N northward. Scattered moderate convection is noted along and east of the front to 135W. The associated pressure gradient is producing fresh SE winds across the NW corner of the forecast region, mainly N of 25N and W of 137W. Seas are 9 to 11 ft in this area in a combination of SE wind waves and NW swell. Farther to the southeast, moderate to fresh trade winds and seas 7 to 9 ft are evident from 13N to 21N between 120W and 135W, south of a broad area of high pressure dominating the regional waters. Gentle to moderate winds and seas of 4 to 6 ft are noted elsewhere. For the forecast, the extratropical cyclone west of the area will drift northward through tonight, then move NW on Sun while weakening. To the east of this system, fresh SE to S winds will persist across the waters north of 25N and west of 137W through early Sun morning. Large NW swell will continue to propagate across much of the northern and western waters through Sun night, sending seas of 8 ft or greater as far east as 124W and as far south as 04N. Marine conditions will begin to gradually improve Mon through mid week. Looking ahead, a strong cold front is expected to approach the far NW waters Thu morning. $$ Stripling
