--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-01-22 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC220236_C_KWBC_20260122023643_12124482-4433-TWDEP.txt ****0000003524**** AXPZ20 KNHC 220236 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Thu Jan 22 2026 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 0230 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 10N95W to 05N95W. The ITCZ continues from 05N95W to 04N105W to 05N125W to 06N140W. Scattered moderate convection is noted from 03N to 06N between 105W and 110W, from 07N to 09N between 115W and 125W, and from 10N to 15N between 135W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to near- gale force gap winds persist across the Gulf of Tehuantepec. Combined seas downstream of the Gulf are 7 to 9 ft in a mix of swell reaching to near 10N100W. Outside of the Tehuantepec area, gentle to moderate winds and moderate seas persist across the Mexican offshore waters. For the forecast, fresh to strong gap winds and occasionally rough seas will prevail in the Gulf of Tehuantepec through Thu night. Elsewhere, gentle to moderate winds will prevail through the weekend. Another gap wind event in the Gulf of Tehuantepec may start Sun night, with gale force winds possible starting Monday. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong gap winds, and seas of 6 to 8 ft, prevail across the Gulf of Papagayo, extending southwest to 90W. Rough seas of 6 to 8 ft are well offshore Guatemala in swell generated by the previous Gulf of Tehuantepec gale force gap wind event. Fresh to locally strong N winds and 4 to 6 ft seas are evident across the Gulf of Panama. Elsewhere, winds are moderate or weaker with seas in the 3 to 5 ft range. For the forecast, the pressure gradient between high pressure north of the area and the eastern north Pacific monsoon trough will support fresh to strong NE to E winds and rough seas in the Papagayo region through at least Fri. The pressure gradient will also support pulsing of moderate to fresh N winds over the Gulf of Panama through tonight. Elsewhere, winds will be moderate or weaker over the forecast waters through the end of the week. NW to N swell generated by previous gales over the Gulf of Tehuantepec well offshore Guatemala will subside tonight. Another possible gale force gap wind event over Tehuantepec will bring a new set of large NW to N swell over the waters well offshore Guatemala early next week. ...REMAINDER OF THE AREA... A plume of combined seas of 7 to 8 ft consisting of shorter- period NE and E winds waves generated from the ongoing Tehuantepec and Papagayo gap wind events mixing with longer period NW swell extends across the area from 05N to 09N between 95W and 115W. Gentle to moderate breezes and moderate combined seas, primarily in NW swell, dominate elsewhere. For the forecast, the plume of rough seas that originated from the gap wind events will subside through tonight. Elsewhere, winds should remain moderate or weaker, with seas less than 8 ft, for the next several days. $$ Christensen ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC220926_C_KWBC_20260122092647_12124482-4458-TWDEP.txt ****0000003329**** AXPZ20 KNHC 220926 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Thu Jan 22 2026 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 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 07N78W to 09N85W to 05N100W. The ITCZ continues from 05N100W to 04N110W to 05N125W to 07N140W. Scattered moderate convection is noted from 03N to 06N between 95W and 100W, from 03N to 07N between 105W and 110W, and from 07N to 12N between 120W and 135W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to near- gale force gap winds persist across the Gulf of Tehuantepec with 7 to 9 ft. Outside of the Tehuantepec area, gentle to moderate winds and moderate seas persist across the Mexican offshore waters. For the forecast, fresh to strong gap winds and occasionally rough seas will prevail in the Gulf of Tehuantepec through tonight. Elsewhere, gentle to moderate winds will prevail through the weekend. Another gap wind event in the Gulf of Tehuantepec will start Sun night, with gale force winds possible Mon and strong gales by Mon night accompanied by rough to very rough seas. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong gap winds, and seas of 6 to 8 ft, prevail across the Gulf of Papagayo, extending southwest to 90W.
