000 AXPZ20 KNHC 210357 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Mar 21 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 0350 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 10N75W to 08N87W to 03N102W. The ITCZ continues from 03N102W to 05N111W to 03N121W to beyond 05.5N140W. Scattered moderate isolated strong convection is noted from 00N to 07N E of 89W, and from 04.5N to 08.5N between 97W and 118W. Scattered moderate to strong convection is noted from 05N to 10N W of 133W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Fresh to strong NW winds follow a cold front moving across Baja California Sur offshore waters where recent altimeter data show seas of 8-12 ft in NW swell. Fresh to strong NW winds are across the central portion of the Gulf of California with seas in the 5-8 ft range. In the Gulf of Tehuantepec, fresh to near gale force N to NE winds continue tonight with seas of 5-8 ft. Gentle to locally moderate NW winds are elsewhere along the SW Mexican offshore waters where wave heights of 4-6 ft prevail. Fresh to near gale-force northerly winds in the Gulf of Tehuantepec will gradually diminish to moderate winds by Mon morning. Fresh to strong NW winds and building seas in NW swell followinf the cold front will reach the waters of Cabo San Lucas tonight. The front will dissipate on Mon and winds will diminish to moderate speeds Mon night. Fresh to strong NW winds in the Gulf of California will diminish to moderate to fresh speeds on Mon and then prevail through the middle of the week. Gale force winds are likely to develop with the next gap wind event in the Tehuantepec region forecast to begin early on Thu. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to strong gap winds are blowing across the Papagayo region with seas of 5-7 ft. Gentle to moderate northerly winds are in the Gulf of Panama where seas are 3-5 ft. Light to gentle winds are elsewhere along with wave heights of 3-5 ft due to SW swell. Fresh NE to E winds are expected across the Papagayo region, pulsing to strong each night through early morning, continuing through Tue, before diminishing modestly through Thu. Peak seas tonight through Tue morning will reach near 8 ft offshore. Moderate to fresh N winds are expected in the Gulf of Panama at night through Mon night before diminishing. Cross equatorial SW swell will continue to affect the offshore forecast waters with seas of 3-5 ft. REMAINDER OF THE AREA A 1033 mb high pressure system centered near 35N132W dominates the waters N of the ITCZ and W of about 110W. This high pressure center is to the NW of a cold front that is across the Baja California offshore waters and adjacent NE waters along about 128W. The front will continue to move SE reaching the offshore waters of Baja California Sure tonight before dissipating Mon. This weather pattern will bring increasing winds and building seas across much of the forecast waters W of 110W. The high pressure will drift SW and weaken slightly through Tue. This combined with lower pressures in the vicinity of the ITCZ will result in a large area of fresh to strong trade winds across the west-central waters W of 125W through Tue night. Seas of 8-10 ft are expected within the area of trade winds. $$ Ramos
