000 AXPZ20 KNHC 252121 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Fri Nov 25 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 on1800 UTC surface analysis and satellite imagery through 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the Costa Rica/Panama border to 1011 mb low pressure near 08N90W, then to 1011 mb low pressure near 11N121W to another 1011 mb low pressure near 09N128W to beyond 07N140W. Scattered moderate to isolated strong convection is noted from 07N to 14N between 103W and 120W, and from 06N to 10N W of 130W. A cluster of moderate to isolated strong convection is within 150 nm N quadrant of low located near 09N128W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to strong NW to N winds are blowing across most of the Gulf of California. The enhanced winds have been due to strong high pressure centered north of the area over the Great Basin. This is shifting eastward, allowing the gradient to gradually relax from north the south. Fresh to strong NE winds continue through the various gaps along the Baja California peninsula. The long fetch of NW winds is resulting in wave heights to 8 ft over the central and southern Gulf of California. Seas of 6 to 8 ft are across the offshore waters of Baja California between Cabo San lazaro and Punta Eugenia due to the gap winds. Farther south, light to gentle NW to N winds and moderate seas are evident across the offshore waters of southern Mexico. For the forecast, strong high pressure over the Great Basin of United States will continue to induce fresh to strong NW to N winds over most of the Gulf of California through early Sat. These winds could spread through the gaps in the mountains over Baja California into the waters west of Baja California, particularly between Cabo San lazaro and Punta Eugenia through tonight. Looking ahead, fresh to locally strong SW winds may develop in the northern Gulf of California Mon night into Tue due to an approaching cold front, while building NW swell arrives offshore Baja California Norte. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate NE winds prevail across the Papagayo region with seas of 4-5 ft. Light to gentle variable winds and 5-6 ft seas in mainly SW swell prevail elsewhere north of the monsoon trough. Mainly moderate S to SW winds are occurring south of the monsoon trough. Seas are 4-6 ft in SW swell south of the monsoon trough, except 1-3 ft in the lee of the Galapagos Islands. For the forecast, moderate winds and seas will persist across the region into early next week. Fresh gap winds may pulse across the Gulf of Papagayo and the coast of Nicaragua Mon night through Wed night. REMAINDER OF THE AREA... An extratropical cyclone of 1000 mb is centered west of the area near 28N148W. This system is producing fresh to strong southerly winds across the NW corner of the forecast region, mainly N of 25N and W of 138W. Combined seas are 10 to 13 ft in this area in a combination of SE wind waves and NW swell. Farther to the southeast, fresh trade winds and seas to 8 ft are evident from 15N to 20N between 120W and 126W, south of a broad area of high pressure dominating the waters north of 20N. Moderate winds and seas are noted elsewhere. For the forecast, the extratropical cyclone west of the area will move little through Sat, then move NW on Sun while weakening. To the east of this system, fresh to strong 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 area through Sun night, sending seas of 8 ft or greater as far east as 125W and as far south as 05N. Seas will peak around 12 ft along 140W N of 20N through tonight. Marine conditions will begin to gradually improve Mon through mid week. $$ GR
