000 AXPZ20 KNHC 072200 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Wed Feb 7 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...SPECIAL FEATURES... Significant Northerly Swell: Large, long-period northerly swell continues to propagate southeastward across the east Pacific. North of 19N, swell has decayed enough to allow seas to drop below 12 ft this afternoon. South of 19N, swell continues to sustain seas of 12 to 15 ft west of a line from 19N125W to 10N122W. This swell will persist from 05N to 18N through Thu before gradually decaying the rest of the week. Please read the latest High Seas Forecast issued by the National Hurricane Center at the website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... An equatorial trough extends west-southwestward from 07N77W to 03N95W. An ITCZ continues westward from 03N95W to 08N126W, and from 07N131W to beyond 05N140W. Scattered moderate convection is noted up to 120 nm along either side of the trough west of 83W, and up to 90 nm along either side of the ITCZ. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A dissipating cold front curves southwestward from near Culiacan, Mexico across waters south of Cabo San Lucas to beyond 17N113W. Patchy showers are occurring near and up to 80 nm east of this boundary. Moderate with locally fresh northeasterly gap winds along with 6 to 8 ft seas are found at the Gulf of Tehuantepec and nearby waters. Fresh to strong SW winds and seas of 5 to 7 ft are noted in the northern Gulf of California. Fresh NW winds with seas at 4 to 6 ft are present north of the front at the Gulf of California entrance. Gentle to moderate NW winds and seas at 2 to 3 ft exist elsewhere within the Gulf. Moderate to fresh NW to N winds with 8 to 10 ft seas in large NW swell are present across the Baja California and Revillagigedo Islands offshore waters. For the remaining offshore waters off central and southern Mexico, mainly light to gentle winds and seas at 4 to 6 ft prevail. For the forecast, fresh to strong gap winds and rough seas at the Gulf of Tehuantepec and nearby waters will steadily subside through this afternoon. Fresh to strong SW winds will prevail in the far northern Gulf of California through Thu. Large, long- period NW swell over the offshore waters of the Baja California Peninsula will spread southward to the Revillagigedo Islands today. Seas will gradually subside by the end of the week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR Fresh to strong NE to E gap winds and 5 to 7 ft seas are seen in the Gulfs of Papagayo and Panama. In the offshore waters of Guatemala and El Salvador, gentle to moderate ENE winds are present with 3 to 5 ft seas near the coast and 6 to 8 ft seas in residual N swell farther out. Gentle to moderate southerly winds and seas at 4 to 6 ft in mixed moderate swells dominate waters near the Galapagos Islands and west of Ecuador. Light to gentle winds with 3 to 4 ft seas prevail for the rest of the offshore waters For the forecast, residual swell generated by the gap winds in the Tehuantepec region will sustain rough seas over the outer offshore waters of Guatemala and El Salvador through early this afternoon. Fresh to strong gap winds in the Papagayo region will pulse to near-gale force during the nighttime and early morning hours through Fri night. Fresh to strong gap winds will develop in the Gulf of Panama by late this afternoon. Conditions at both locations will start to improve later this weekend. ...REMAINDER OF THE AREA... See the Special Features Section for information on an ongoing large swell event. A dissipating cold front continues southwestward from the offshore waters of Revillagigedo Islands across 17N113W to 145116W. Patchy showers are evident near and up to 80 nm east of this feature. Farther south, a surface trough is causing scattered moderate convection from 07N to 11N between 126W and 131W. A broad surface ridge extends southeastward from the north-central Pacific across 30N140W to near 19N116W. The pressure gradient between the ridge and cold front is supporting moderate to fresh winds north of 20N. The pressure gradient between the same ridge and lower pressure in the vicinity of the ITCZ is sustaining fresh to strong trade winds north of the ITCZ to 20N and west of 115W. Gentle to moderate winds generally prevail elsewhere. Outside the Significant Swell area mentioned in the Special Features section, seas of 8 to 11 ft cover are seen up to 150 nm northwest of a line from 20N115W to 13N116W to 07N120W to 00N136W. Seas of 5 to 7 ft prevail elsewhere. For the forecast, fresh to strong trade winds will prevail north of the ITCZ through Fri before diminishing this weekend. $$ Chan
