The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0130 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: the pressure gradient between high pressure building in the wake of a strong cold front in the Gulf of America and the eastern north Pacific monsoon trough has ushered in a round of gale conditions in the Tehuantepec region. These winds should reach strong- gale force, with seas peaking near 18 to 22 ft Sat through Sun morning. Winds will diminish below gale force Tue morning. Another gale force gap wind event is possible in Tehuantepec starting Wed night. Please read the latest High Seas Forecast issued by the National Hurricane Center at https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 08N84W to 03N98W. The ITCZ extends from 03N98W to 03N118W to beyond 04N140W. Scattered moderate convection is noted from 04N to 08N between 84W and 94W, and from 06N to 10N between 112W and 128W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A Gale Warning is in effect for the Gulf of Tehuantepec through early next week. Please see the Special Features section above for more details. Aside from the Gulf of Tehuantepec, the pressure gradient between surface ridging west of the Baja Peninsula and a surface trough over western Mexico is supporting fresh to strong NW winds in the Gulf of California. Seas are slight to moderate over these waters. Moderate to locally rough seas are west of the Baja California peninsula. Elsewhere, winds are moderate or weaker with moderate seas. For the forecast aside from the Gulf of Tehuantepec, fresh to strong NW to N winds will prevail across the Gulf of California before diminishing Sat afternoon. A set of NW swell will impact the waters west of the Baja California peninsula late Sun night through Tue. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE winds, and seas of 5-6 ft, prevail in the Gulf of Papagayo region extending westward to near 88W. Moderate to fresh gap winds are over and downstream of the Gulf of Panama, with moderate seas. Over the remainder of forecast waters, gentle to moderate winds and moderate seas prevail. For the forecast, fresh to strong NE to E gap winds in the Gulf of Papagayo will possibly peak at gale-force Sun night through Tue as an Arctic high pressure building over the eastern United States helps tighten the pressure gradient. A gale force gap wind event over the Gulf of Tehuantepec will produce rough to very rough seas over the western Guatemala and El Salvador waters Sat night through Mon. Fresh to strong northerly gap winds along with rough seas are also expected near the Gulf of Panama Sat evening through Tue night. ...REMAINDER OF THE AREA... Surface ridging prevails across the waters N of 20N. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ is supporting moderate trades from north of the ITCZ to near 20N and west of about 118W. A cold front is approaching the NW waters. Large NW swell generated from that system has moved into the NW waters, with seas in the 8-11 ft range. Elsewhere, moderate winds, and moderate seas in mixed swell, prevail. For the forecast, the aforementioned cold front will weaken through Sat, then dissipate on Sun. Large NW swell over the NW waters, with rough to very rough seas, will impact the waters north of 15N and west of 130W through Sun, then rough seas further spreading southeastward to cover the waters north of 05N and west of 120W by Mon before gradually subsiding. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC310920_C_KWBC_20260131092045_25559334-1620-TWDEP.txt ****0000004520**** AXPZ20 KNHC 310920 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sat Jan 31 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.
