000 AXPZ20 KNHC 241526 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Thu Mar 24 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURE... Gulf of Tehuantepec Gale Warning: Gale force gap winds, N at 25 to 35 kt, are beginning in the Gulf of Tehuantepec this morning. Gales will prevail through Sat night, peaking around 40 kt Fri and Fri night. The gap winds are being caused by high pressure building south through the western Gulf of Mexico. Seas currently up to 8 ft will increase to 12 to 14 ft tonight into Fri night. As high pressure weakens and moves east, winds and seas will decrease for the start of next week. Please read the latest NWS High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends Panama near 07N80W to 05N94W to 04N112W. The ITCZ then stretches from 04N112W to 06N125W to beyond 06N140W. Scattered moderate to isolated strong convection is present from 02S to 09N and between 80W and 112W. Scattered moderate convection is seen from 03N to 09N and between 113W and 121W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Please see above in the Special Feature for details about a Gulf of Tehuantepec Gale Warning. Fresh to strong NW winds are ongoing in the central and southern Gulf of California as high pressure surges south. Across the northern Gulf, gentle to moderate winds prevail. Seas in the area of fresh to strong winds average 5 to 7 ft, with 2 to 4 ft seas elsewhere in the Gulf. To the west of Baja California, gentle to moderate N winds prevail with seas of 4 to 6 ft. Elsewhere offshore Mexico, mainly gentle to moderate winds prevail, with locally fresh N winds occurring offshore Cabo Corrientes. Seas average 4 to 6 ft. For the forecast, fresh to strong NW winds in the Gulf of California will diminish this afternoon to primarily moderate. Fresh to strong southerly winds will develop in the northern Gulf of California Sun night through Mon night. Moderate NW swell west of the Baja California peninsula will gradually subside over the next couple of days. A larger set of NW swell may impact the waters offshore of Baja California early next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Moderate to fresh E winds continue to affect the Papagayo region to 88W, with moderate to locally fresh N winds in the Gulf of Panama. Elsewhere, gentle to moderate winds prevail north of the equator, while mainly moderate S to SE winds are found south of the equator. Seas of 3-5 ft are prevalent, except 4-6 ft offshore of Ecuador in long period S-SW swell. For the forecast, Caribbean trades will continue to cause moderate to fresh winds in the Papagayo region, increasing to fresh to strong starting early Fri through early next week. Winds in the Gulf of Panama will pulse to fresh to locally strong starting Fri night through early Sun. Elsewhere, winds are forecast to be moderate or weaker through the upcoming weekend. W to NW swell from a Gulf of Tehuantepec gap wind event will begin impacting the Guatemala and El Salvador offshore zones Thu night, continuing through Sunday morning. REMAINDER OF THE AREA The high pressure system of 1026 mb remains positioned near 33N132W, just north of our forecast area, and continues to dominate the region. The pressure gradient between the subtropical ridge and lower pressures in the deep tropics is causing moderate to fresh trades, primarily N of 10N and W of 125W. Seas in the area described are 6-9 ft. Elsewhere, moderate or weaker anticyclonic winds and 5-7 ft seas prevail. For the forecast, the high pressure north of our area is forecast to continue to weaken, allowing the trades to diminish. Moderate to gentle winds will prevail over most of the High Seas late this week through the weekend. Seas will also decrease somewhat as result of the diminishing winds. Later, a robust extratropical low is expected to move eastward while centered just north of our 30N border this weekend, dragging an attendant cold front across the northern waters. This system is forecast to bring increasing winds and building seas north of 25N west of 120W through the weekend, spreading east through early next week. $$ KONARIK
