000 AXPZ20 KNHC 171644 TWDEP Tropical Weather Discussion...Updated NWS National Hurricane Center Miami FL 1605 UTC Sun Apr 17 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 1200 UTC surface analysis and satellite imagery through 1630 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N78W through 08N110W to 07N141W. An ITCZ continues from 07N141W to beyond 06N140W. Scattered moderate to isolated strong convection is noted from 03N to 07N between 81W and 106W. Numerous moderate convection is seen from 05N to 10N between 130W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Tight pressure gradient between a 1024 mb high pressure centered near 29N128W and lower pressure across Mexico is supporting NW winds, fresh to strong off Baja California Norte, and moderate to fresh off Baja California Sur and the Jalisco region. Light to gentle variable winds are elsewhere in the SW offshore waters of Mexico, and Gulf of California. Seas are in the 5 to 8 ft range offshore of the Baja California peninsula, 3 to 5 ft in the S and SW Mexican offshore waters, and 1 to 3 ft in the Gulf of California. Patchy areas of haze are possible at the offshore waters of southern Mexico due to nearby agricultural fires. For the forecast, fresh to strong NW winds off Baja California Norte will subside briefly to between moderate and fresh Wed night through Thu night. Waters offshore from Baja Norte will persist near 8 ft with the strongest winds through this afternoon. Moderate northerly swell W of the Baja California peninsula will continue through Thu. Starting Thu evening, large NW swell associated with a cold front off the California coast should arrive at Baja California offshore waters. Moderate to fresh northerly winds are expected in the southern Gulf of California, and along the S and SW Mexican offshore waters this evening through Mon afternoon. Fresh to strong northerly winds will continue off the Jalisco region until later this afternoon, and occur near the Gulf of Tehuantepec Mon evening through early Tue morning. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Moderate to fresh NE to E winds are over the Papagayo region offshore southern Nicaragua, while gentle to moderate S to SW winds are between Ecuador/southern Colombia and the Galapagos Islands. Light to gentle winds prevail elsewhere. Seas are in the 4 to 6 ft range in the Papagayo region as well as the Ecuador offshore waters. Seas at 4 to 5 ft are found offshore from Guatemala-El Salvador, and near the Costa Rica-Panama-Colombia area. Patchy areas of haze are possible at the offshore waters of Guatemala, El Salvador, and Nicaragua due to nearby agricultural fires. For the forecast, high pressure will continue to support pulses of fresh winds near the Papagayo region offshore southern Nicaragua through this afternoon. Moderate winds in the Gulf of Panama will continue through this afternoon. Gentle to moderate southerly winds will prevail between Ecuador/southern Colombia and the Galapagos Islands through this afternoon, then become moderate to fresh and shift northwestward to the offshore waters of Costa Rica and western Panama tonight through Mon afternoon. Light to gentle winds are expected elsewhere. REMAINDER OF THE AREA A surface ridge extending from a 1024 mb high near 29N128W dominates much of the NW forecast waters, providing moderate to fresh NE to ENE winds N of the ITCZ and surface trough to 24N and W of 118W. Seas within this area are in the 6 to 7 ft range, except near 8 ft in the vicinity of 08N134W. Winds are mainly light to gentle elsewhere with seas at 4 to 6 ft. For the forecast, a very weak low along the surface trough near 09N122W will strenghten slightly while moving westward through midweek, thus increasing the winds and seas near and N of its center. $$ Chan
