000 AXPZ20 KNHC 262054 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sat Nov 26 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 1800 UTC surface analysis and satellite imagery through 2030 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N77W to 10N111W to 08N140W. Scattered moderate isolated strong convection is noted from 06N to 12N between 85W and 129W. 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. To the south, mainly gentle wind prevails. Seas from Cabo Corrientes northward are 5 to 7 ft, with 3 to 5 ft seas to the south. Seas in the central and southern Gulf of California are 3 to 5 ft, with 1 to 3 ft seas to the north. 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. SW winds to the N and E of a low pressure passing N of the area Mon into Tue will develop in the northern Gulf of California Mon then increase to strong Mon night. Looking ahead, strong gap winds are possible in the Tehuantepec region starting Wed night. 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, with mainly moderate S to SW winds and 4 to 6 ft seas to the S. There is lesser seas of 2 to 4 ft in the lee of the Galapagos Islands. 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 998 mb low pressure system is centered west of the area near 29N147W. A stationary front to the east of the low extends N to S along 141W from 25N northward. Scattered moderate convection is noted along and east of the front to 137W. The associated pressure gradient is producing fresh SE winds across the NW corner of the forecast region, mainly N of 24N and W of 138W. Seas are 10 to 12 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 130W, south of a broad area of high pressure dominating the waters north of 20N. 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 138W 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. $$ KONARIK
