000 AXPZ20 KNHC 270858 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sun Feb 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 0930 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: N winds are forecast to increase to gale force across the Gulf ofehuantepec Sun evening and last through Mon night with seas building to 16 ft over the area. Near gale force N winds will then continue Tue through Wed, with gale force winds possible again Wed night into Thu. Please read the latest High Seas Forecast issued by the National Hurricane Center at website http://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from the coast of northern Colombia near 05N77W to 04N97W. The ITCZ continues from 04N97W to 07N119W to 05N140W. Scattered moderate convection is noted from 04N to 14N between 113W and 124W. This is more due to an upper-level trough rather than due to the proximity of the ITCZ. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Please see the Special Features section above for details on the Gale Warning in the Gulf of Tehuantepec. A 1030 mb high pressure is centered near 32N126W. Recent ASCAT satellite wind data shows moderate N winds to the west of Baja California and fresh N winds in the central and southern Gulf of California. Fresh to strong NW winds are likely occurring in the southern and central Gulf of California. Light to gentle winds prevail in the offshore waters from Manzanillo through the state of Oaxaca. Strong to near gale force N winds prevail in the Gulf of Tehuantepec. Seas west of Baja California are 4-6 ft. Seas of 5-6 ft are over the southern Gulf of California and over the entrance to the Gulf, while 3-4 ft seas prevail elsewhere over the Gulf. Seas are 3-5 ft are elsewhere, except up to 9 ft offshore the Gulf of Tehuantepec. For the forecast, fresh to strong NW winds over the southern two-thirds of the Gulf of California will continue through Sun night before gradually diminishing Mon into Mon night. Seas will build to 6-7 ft S of Tiburon Island through Sun night. Moderate to locally fresh N winds and modest seas will prevail west of Baja California, to the south of El Rosario, through Sun. Long period NW swell will reach the waters west of Baja California Sun night, where seas of 7-8 ft will prevail offshore through Mon night, before subsiding Tue. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to locally strong NE gap winds are currently occurring over the region offshore Papagayo and and moderate to fresh N winds are over the Gulf of Panama N of 05N. Seas are 6-7 ft in the Papagayo region, and 4-5 ft south of the Gulf of Panama. Seas of 3-4 ft are occurring elsewhere, except 4-6 offshore Guatemala and El Salvador due to swell from the gap events occurring in Tehuantepec and Papagayo. For the forecast, fresh to strong NE winds will continue to pulse each night across the Papagayo region through late next week. Winds will pulse to fresh to strong across the Gulf of Panama tonight, then continue pulsing to fresh at night into the middle of next week. Gentle winds will persist elsewhere. REMAINDER OF THE AREA Light to gentle anticyclonic winds are occurring north of 27N to 32N in association with the ridge axis near 32N126W. The gradient between the ridge and lower pressure along the ITCZ is producing fresh to strong trades from the ITCZ to 24N between 120W-140W. A broad area of cloudiness associated with upper-level diffluence, to the east of an upper-level trough, is producing scattered showers and isolated thunderstorms with fresh to strong winds and occasional gusts to gale force from 10N to 13N between 119W and 124W. Seas are 8-10 ft in this area, as confirmed by recent satellite altimeter data. A set of NW swell has already crossed 125W. Seas north of 21N and west of 135W have recently built to 8 to 10 ft. Seas of 5-7 ft prevail elsewhere. For the forecast, high pressure will remain in control over the region, maintaining fresh to strong trades across much of the area from the ITCZ to 21N, and west of 117W through Sun night. The new set of long period NW swell over the western part of the area will continue to spread over most of the area through early Mon, keeping 8-11 ft seas north of 05N and west 120W through at least Mon. Looking ahead, a cold front is forecast to enter the area, passing SE of 30N140W around the middle of next week. $$ Torres
