000 AXPZ20 KNHC 162204 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sat Apr 16 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from near the Costa Rica-Panama border through a 1012 mb low near 09N118W to 07N133W. An ITCZ continues from 07N133W to beyond 08N140W. Scattered moderate to isolated strong convection is seen from 03N to 06N between 77W and 90W. Scattered moderate convection is present from 04N to 13N between 105W and 136W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Tighter pressure gradient between a 1023 mb high pressure centered near 27N135W and lower pressure across Mexico is supporting moderate to fresh NW winds off Baja California Norte, and gentle to moderate NW winds 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 6 to 7 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 waters near the Baja California peninsula, mainly near the northern peninsula due to nearby agricultural fires. For the forecast, fresh to strong NW winds off Baja California Norte will prevail through early Wed evening, then becoming moderate to fresh afterward. Moderate northerly swell W of the Baja California peninsula will continue through midweek. 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 will develop in the southern Gulf of California, and along the S and SW Mexican offshore waters Sun evening through Mon afternoon. Northerly winds will reach fresh to strong off the Jalisco region this evening thru early Sun morning, and near the Gulf of Tehuantepec Tue night. 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 from Costa Rica-Panama-Colombia. For the forecast, a 1020 mb high near 27N131W will support pulses of fresh to strong winds near the Papagayo region offshore southern Nicaragua through Sun afternoon. Gentle winds in the Gulf of Panama will increase to moderate this evening through Sun evening, while gentle to moderate S winds will prevail between Ecuador/southern Colombia and the Galapagos Islands through Tue afternoon. Light to gentle winds are expected elsewhere. REMAINDER OF THE AREA A surface ridge extending from a 1023 mb high near 27N135W dominates much of the NW forecast waters, providing mainly moderate NE to E 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 near 10N139W. Winds are mainly light to gentle elsewhere with seas at 4 to 7 ft. For the forecast, a 1012 mb low along the surface trough near 09N118W will move westward through midweek, thus increasing the winds and seas near and N of its center. $$ Chan
