000 AXPZ20 KNHC 251606 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Mon Mar 25 2024 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 FEATURES... Significant Swell Event West of Baja California Norte: NW swell propagating across the offshore waters of Baja California will maintain 12 to 13 ft seas N of Punta Eugenia. Seas are expected to subside below 12 ft by this afternoon, but a large area of 8 to 11 ft seas will persist W of Baja California trough Tue evening. Mariners, especially local fishermen need to monitor these dangerous marine conditions and plan their routes accordingly. Please refer to the High Sea Forecast issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more detail. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... An equatorial trough extends westward from the coastal border of Western Panama and Costa Rica to 07N97W to 04N115W to 00N134W. The ITCZ continues from 00N134W to beyond 01N140W. Scattered moderate to isolated strong convection is noted from 00N to 07N between 92W and 100W, and from 02N to 06N between 108W and 127W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please refer to the Special Features section about Significant Swell Event. A 1031 mb high pressure located near 31N147W extends a ridge across the Baja California offshore waters, including also the region between Los Cabos and Las Marias Islands. This system is producing fresh to strong NW winds. Similar wind speeds are noted across the waters S of Cabo San Lucas to about 20N. Large NW swell is producing 10 to 13 ft W of Baja California Norte, and 8 to 11 ft west of Baja California Sur. Fresh to strong westerly gap winds are present in the Gulf of California from 27N to 30N where seas are in the 6 to 7 ft range. Gentle to moderate NW winds and seas at 4 to 6 ft prevail across the remainder of the Mexican offshore waters with a small area of fresh to strong westerly winds just S of Puerto Angel. For the forecast, a ridge will continue to dominate the offshore forecast waters of Baja California over the next several days supporting mainly gentle to moderate NW winds beginning tonight. Seas are expected to subside below 12 ft by this afternoon, but a large area of 8 to 11 ft seas will persist W of Baja California trough Tue evening. In the Gulf of California expect gentle to moderate winds with the exception of moderate to locally fresh SW winds N of 29N this evening, and moderate to locally strong NW winds over the souther part of the Gulf by Wed evening. Looking ahead, the next gap wind event in the Gulf of Tehuantepec is expected on Thu, and might reach gale force. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR Modest convergent southerly winds are generating scattered moderate convection in the vicinity of the Galapagos Islands. Otherwise, light to gentle winds and 3 to 5 ft seas prevail across the offshore waters of central America, Colombia and Ecuador. For the forecast, scattered showers and isolated thunderstorms are anticipated to linger near the Galapagos Islands and well offshore from Panama through Tue. Otherwise, light to gentle winds and slight to moderate seas will prevail across the entire region through Thu night. Starting Fri, gap winds in the Papagayo area and Gulf of Panama will steadily increase. ...REMAINDER OF THE AREA... Please refer to the Special Features section about Significant Swell Event. A surface ridge extends southeastward from a 1031 mb high pressure near 31N147W to near the Revillagigedo Islands. This feature is channeling fresh to strong winds across the offshore waters of Baja California and just south of Cabo San Lucas. In addition, the pressure gradient between the ridge and lower pressures near the equatorial trough/ITCZ supports an area of fresh to strong trades from 10N to 22N W of 130W, and from 12N to 19N between 125W and 130W. Seas are 8 to 11 ft within these winds in mixed NE and NW swell. For the forecast, the high pressure will begin to weaken later this morning, allowing winds north of 25N between 120W and 127W to decrease through this afternoon. For the same reason, winds from 10N to 20N and west of 120W are expected to gradually subside this evening through Tue morning. As the NW to N swell starts to decay this evening, seas north of 10N and west of 120W should slowly subside late tonight through Wed. $$ GR
