000 AXPZ20 KNHC 260339 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Apr 26 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. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: North to northeast minimal gale-force winds of 30 to 35 kt will begin across the Gulf of Tehuantepec late Tue night, 27/0600 UTC. Gales are forecast to continue through Wed afternoon, with fresh to strong winds prevailing across the region through Thu afternoon. Seas will build 8 to 10 ft Tue night through Wed night. Please read the latest High Seas Forecast issued by the National Hurricane Center website: https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from the coast of Costa Rica near 09N84W to 09N97W to 09N110W. The ITCZ extends from 09N110W to 07N130W to beyond 06N140W. Scattered moderate convection is noted from 05N to 10N and E of 100W and from 07N to 13N W of 105W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Surface ridging continues to prevail west of the Baja California peninsula. The pressure gradient between the high pressure NW of the area and lower pressure over Mexico is supporting moderate NW to N winds off Baja California Norte. Mainly gentle N winds prevail across Baja California Sur. Seas mostly range 5 to 7 ft in long- period NW swell across the western offshore waters of Baja California. Seas to 8 ft are noted in the extreme northwest portions of the Baja offshores. Light to gentle winds and seas of 5 to 7 ft in mixed swell are noted across the S Mexico offshore waters. Gentle to moderate NW winds prevail across the Gulf of California. Seas are up to 4 ft at the entrance of the Gulf of California, and 2 to 3 ft elsewhere in the Gulf. Patches of haze are possible offshore S Mexico due to nearby persistent agricultural fires. Thunderstorms are also noted along the eastern coast of the Gulf of Tehuantepec. For the forecast, gale- force northerly winds are expected across the Gulf of Tehuantepec Tue night through Wed afternoon. Fresh to strong northerly winds will continue through Thu afternoon in this region. Meanwhile, gentle to moderate northerly winds will prevail across the Baja California offshores through Thu, increasing to fresh by the end of the week. The long- period NW swell will prevail NW of Punta Eugenia through the end of the week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Light to gentle mainly N winds prevail N of the surface trough, with gentle to locally moderate S winds to the S. Seas of 3-5 ft are noted across the Central American offshores with 4-6 ft across the South American offshores. These seas are within a moderate S to SW swell. Patches of haze are possible offshore of Guatemala and El Salvador due to nearby persistent agricultural fires. Scattered thunderstorms are noted off the coasts of Costa Rica and Nicaragua. Isolated thunderstorms are noted off the coasts of Panama and Colombia. For the forecast, long-period moderate S to SW swell will persist across the region through most of the week. Fresh easterly winds will begin near the Papagayo region and offshore Nicaragua on Wed afternoon, and increase to fresh to strong Wed night. Fresh winds will continue in that area on Thu and Fri. Patchy smoke from agricultural fires in southern Mexico and northern Central America may impact waters offshore Guatemala and El Salvador at times. REMAINDER OF THE AREA The gradient between high pressure centered N of the area and lower pressure along the ITCZ is supporting moderate to fresh NE winds N of the ITCZ and W of 115W. Long- period NW to N swell throughout this area is producing seas of 8-10 ft. Gentle to moderate winds along with seas of 5-7 ft seas due to long-period S to SW swell are noted elsewhere. For the forecast, the long-period NW to N swell will gradually decay through Tue night, which will allow for seas to subside through Thu. The southerly swell should sustain 5-7 ft seas across the remainder of the basin through the forecast period. $$ AReinhart
