000 AXPZ20 KNHC 210332 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Feb 21 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 0300 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from a 1008 mb low pressure over northern Colombia near 09.5N74.5W to 03N95W. The ITCZ continues from 03N95W to 07N128W to beyond 07N140W. Scattered moderate convection is noted within 90 nm N of ITCZ W of 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Strong gap winds continue this evening across the Gulf of Tehuantepec region and extend offshore to near 14.5N. Seas have diminished to 6-8 ft across the immediate Gulf. However, Merging NW, NE and E swell across the outer offshore waters are maintaining seas of 7-9 ft. Winds will diminish to a narrow plume of strong gap winds late tonight through Mon morning as high pressure continues to weaken across the Gulf of Mexico. Winds will then diminish to below 20 kt Mon evening. Favorable marine conditions are expected to prevail across Tehuantepec throughout the week. A broad ridge continues to extend modestly across the offshore forecast waters of Baja California, producing gentle to moderate NW winds and seas of 3-5 ft. Afternoon scatterometer data indicated light and variable winds over the central and south parts of the Gulf of California, including the entrance to the Gulf. Seas there are generally 1 to 3 ft. Seas generated by strong winds off California are forecast to reach the waters N of Punta Eugenia Mon night into Tue. Southerly winds will prevail across the north and central parts of the Gulf of California through Tue night. Looking ahead, fresh to strong NW winds and building seas are expected late Tue through Wed offshore Baja California Norte, while strong SW to W winds develop across the northern Gulf of California as a cold front or frontal trough moves across the area. Seas could reach 8 ft in the northern Gulf of California Tue night into Wed. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to strong NE gap winds are noted across the Gulf of Papagayo region and downwind to near 10N89W. Moderate to fresh northerly winds prevail inside the Gulf of Panama. Light to gentle winds remain elsewhere. Seas of 3-6 ft prevail across the area except 6 to 9 ft downwind of Papagayo. A strong gap wind event is expected across the Papagayo region through Mon night as a strong high pressure ridge continues to dominate the Gulf of Mexico, western Atlantic and Caribbean. The strongest winds of 25 to 30 kt are expected tonight, and again Mon night, with seas building 8-10 ft downstream of the Papagayo region to about 90W-91W. Then, fresh to strong winds of 20-25 kt will prevail across the Papagayo area through Wed night. Fresh to locally strong N winds will pulse in the Gulf of Panama each night through Mon night, with seas building to 7 ft. Seas generated in the Tehuantepec and Papagayo gap wind areas are forecast to propagate into the offshore waters of Guatemala and El Salvador through Mon. Light to gentle winds will remain elsewhere. REMAINDER OF THE AREA Strong high pressure located well NW of the area extends a ridge SE to near the Revillagigedo Islands covering the waters north of the ITCZ. The pressure gradient between the high and ITCZ is producing an area of fresh to locally strong trades over the open waters N of the ITCZ to about 16N and W of 115W. Seas in the trade wind area are 9 to 10 ft in mixed NW swell and NE wind waves. Elsewhere, from 05N to 16N and W of 122W seas are 7-9 ft also in mixed long period NW swell and NE wind waves. Fresh to locally strong trade winds will continue north of the ITCZ to about 15N and west of 125W over the next couple of days. Seas generated by strong winds off California are forecast to reach the NE waters by late Mon and raise seas to 8-9 ft. The aerial extent of the trade winds will increase by Wed as a strong high pressure settles N of area. By that time, fresh to locally strong NE to E winds and building seas are forecast to cover the waters from 10N to 22N and W of 125W. $$ Stripling
