000 AXPZ20 KNHC 010456 TWDEP Tropical Weather Discussion...Update NWS National Hurricane Center Miami FL 0405 UTC Sun Jan 1 2023 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 0430 UTC. ...SPECIAL FEATURES... Northern Gulf of California Gale Warning: A cold front approaching Baja California have increased westerly winds toward the peninsula, which will produce near-gale to gale force SW to W gap winds over the northern Gulf of California late tonight through mid Sun morning. Please read the latest Pacific Ocean High Sea Forecast at website: www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest Offshore Waters Forecasts at website: www.nhc.noaa.gov/marine/offshores_eastpac.php for more information. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A monsoon trough extends from 09N84W to 07N100W to 08N113W. Widely scattered moderate convection is present from 03N to 11N between 77W and 110W. An ITCZ extends from 10N116W to 07N130W to beyond 07N140W. Scattered moderate convection is noted from 05N to 09N between 116W and 140W. Updated the following sections OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weakening surface ridge near 24N125W is sustaining gentle to locally moderate northerly winds with 4 to 6 ft seas across the offshore waters of Baja California and central Mexico. Moderate to locally fresh SW to W winds and seas of 3 to 5 ft are found at the northern Gulf of California, while light to gentle winds and 1 to 3 ft seas prevail for the rest of the Gulf. Mainly gentle winds and seas at 4 to 6 ft are seen offshore from southern Mexico. For the forecast, westerly gap winds at the northern Gulf of California will reach near-gale to gale force from late tonight through mid Sun morning. Afterward, these winds will gradually subside through Sun night. Fresh to locally near-gale northerly winds are expected across the waters west of Baja California from early Sun through early Mon, large NW swell will persist through Mon afternoon. Lastly, gale-force gap winds are possible at the Gulf of Tehuantepec after midweek. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to locally strong easterly winds are noted over the Papagayo region, with light to gentle winds elsewhere north of the monsoon trough. Gentle to moderate southerly winds exist south of the monsoon trough. Seas across all the offshore waters range from 4 to 7 ft, except 2 to 5 ft near the Galapagos Islands. For the forecast, fresh to strong easterly winds over the Papagayo region will decrease to fresh late Sun afternoon through Mon. Gentle to occasionally moderate winds will continue elsewhere for the next several days with slight to moderate seas. REMAINDER OF THE AREA... The pressure gradient between surface ridge near 24N125W and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh trade winds, and seas of 6 to 8 ft, north of the ITCZ to 20N and west of 120W. A cold front extending from 31N123W to 28N130W to 27N135W is creating fresh to locally strong winds north of 27N between 122W and 132W. Long-period NW swell associated with the front is causing 9 to 11 ft seas north of 25N and west of 121W. Elsewhere north of the ITCZ/monsoon trough, gentle to locally moderate eastly winds and seas of 5 to 6 ft exist. Gentle to moderate southerly winds with seas of 5 to 6 ft prevail south of the ITCZ/monsoon trough. For the forecast, the cold front will move farther eastward reaching Baja California Norte Sun morning. The front will be from northern Baja California Norte to 25N130W by early Sun morning, then start to dissipate from Baja California Sur near Cabo San Lazaro out to 20N120W by late Sun. Strong to locally near-gale NW winds and 10 to 13 ft NW swell will accompany the front. High pressure building in the wake of the front will support a large area of fresh trade winds over the tropical Pacific waters along the ITCZ west of 135W by early Mon morning, along with combined seas 7 to 8 ft with a component of NW swell. $$ Forecaster Chan
