000 AXPZ20 KNHC 301459 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Sat Jan 30 2021 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 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 1445 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: High pressure building into the western Gulf of Mexico in the wake of a cold front combined with lower pressure associated with the monsoon trough to the south will increase the pressure gradient over the area and gales will develop Sun night in and near the Gulf of Tehuantepec. Winds may peak near 45 kt Mon night, with gales continuing into Tue night. Please see the latest High Seas Forecast at http://nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N75W to 04N89W. The ITCZ extends from 04N89W to 03N107W to 09N123W to beyond 02N140W. Scattered moderate isolated strong convection is noted from 04N to 17N between 118W and 135W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section for details on a Gale Warning for the Gulf of Tehuantepec region. Strong offshore winds prevail in the Tehuantepec region, and gentle to moderate NW winds prevail across the offshore waters of Baja California, where seas are 6-10 ft in NW swell. The cold front that produced this winds off Baja California has devolved into a surface trough along the NW coast of mainland Mexico. Weak high pressure will build across the region today and freshen the local wind flow across the Baja waters, while fresh to locally strong northerly winds develop inside the Gulf of California by tonight and continue through Mon. Seas are expected to build to 7-8 ft across central portions of the Gulf Sun night. Locally strong winds are expected this afternoon and evening along the coast of Cabo Corrientes. Large NW swell off Baja California Norte has peaked in size and will continue to propagate southward across the waters west of the southern Mexico into, while slowly subsiding offshore of Baja California. New NW swell will reach the waters off Baja California Norte by Mon night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Strong offshore winds prevail across the Gulf of Papagayo and Gulf of Panama. Light to gentle winds are noted elsewhere. Seas are in the 7-10 ft range in and downwind of the Gulf of Papagayo, 6-9 ft downwind of the Gulf of Panama, and 3-6 ft elsewhere. Fresh to strong offshore winds will prevail across the Papagayo region into Sun night, then will pulse into late next week. Large seas generated from the Papagayo winds will merge with NW swell moving away from Tehuantepec, and also mix with W swell moving through the region to create confused seas of 7-10 ft across the offshore waters of El Salvador and Guatemala today. Fresh to strong northerly winds will prevail in the Gulf of Panama through early Sun, with seas remaining up to around 8 ft. Generally moderate winds are expected elsewhere. REMAINDER OF THE AREA... Gentle to moderate winds prevail within an area of high pressure N of 25N, with gradually decaying seas of up to 10 ft highest near 30N125W. Large NW swell will continue to move S-SE across the waters this weekend. The pressure gradient between the high to the north and lower pressure in the vicinity of the ITCZ is supporting fresh to locally strong NE trade winds north of the ITCZ to 23N, west of 115W. Seas in this area are in the 8 to 11 ft range in mixed NW swell and NE tradewind swell. Trade winds will increase today through Sun to the W of 120W as high pressure builds north of the area. New NW swell will propagate into the NW waters tonight. $$ KONARIK
