The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0350 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Storm Warning: Storm-force winds are ongoing across the Gulf of Tehuantepec and downwind to about 14N with seas to 21 ft. Gale- force NNE winds extend further south to around 12N with seas in the 12 ft to 20 ft range. Winds will diminish to strong gale force speeds Tue morning, and gradually decrease in areal coverage until diminishing below gale-force late Tue night into Wed morning. Large seas generated from this very strong gap wind event will spread well away from the Tehuantepec area, with seas 8 ft or greater already reaching as far west as 105W, and as far south than 06N tonight. Marine interests transiting across or in the Gulf of Tehuantepec through Tue should be aware of this gap wind event, and take the necessary action to avoid this hazardous marine conditions over the affected waters. Gulf of Papagayo Gale Warning: The pressure gradient between high pressure building N of the area and the equatorial trough is supporting fresh to near gale-force NE to E gap winds over the Papagayo region with seas to 7 ft. The area of high pressure will continue to build, further tightening the pressure gradient, with winds reaching minimal gale conditions Tue morning and seas will become very rough. Gale conditions will remain through Wed morning. Please read the latest NWS High Seas issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml Heavy Precipitation Event: Over the next several days the Pacific coasts of Colombia, Ecuador and NW Peru are expecting heavy precipitation due to persisting moist onshore flow that will interact with the Andes Mountains. Rainfall amounts of 4 to 6 inches (100 to 150 mm) are possible with locally 6 to 8 inches (150 to 200 mm). ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07N83W to 02N95W to 00N108W. The ITCZ extends from 04S107W to 01S130W to 01S140W. Scattered moderate convection is noted from 03S to 06N E of 92W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the SPECIAL FEATURES section for information on a STORM WARNING for the Gulf of Tehuantepec. Aside from the Gulf of Tehuantepec, a ridge of high pressure extends west of Baja California, with a surface trough over western Mexico. The pressure gradient between these features is supporting moderate NW winds over the Gulf of California, with moderate winds west of the Baja California peninsula. Light to gentle winds are elsewhere over the open waters off Mexico. Moderate seas prevail over the open waters off Mexico, as well as across the Gulf of California. For the forecast aside from the Gulf of Tehuantepec, moderate or weaker winds are forecast elsewhere through Sat night. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Please see the SPECIAL FEATURES section for information on a GALE WARNING for the Gulf of Papagayo. Aside from the Gulf of Papagayo, fresh to locally strong N to NE winds prevail in the Gulf of Panama with seas to 4 ft. Elsewhere, light to gentle winds and slight seas prevail. For the forecast aside from the Gulf of Papagayo, fresh to locally strong NE winds, and rough seas, will prevail downwind of the Gulf of Panama and just S of the Azuero Peninsula tonight into Tue. The large wind field of the Tehuantepec gap wind event will produce fresh to strong northerly winds and very rough seas across the offshore waters of Guatemala and El Salvador through tonight. However, rough seas will continue to propagate across these waters through Tue night. ...REMAINDER OF THE AREA... A cold front is over the NW waters. High pressure dominates the waters N of 11N and ahead of the front, being anchored by a 1022 mb high centered near 33N123W. The pressure gradient between the area of high pressure and the cold front over the NW waters is supporting fresh to near-gale force SW winds ahead of the front. The pressure gradient between the area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh trade winds S of 20N and W of 110W. A set of NW swell has propagated into the NW waters, with seas in the 8-14 ft range. Elsewhere, seas of 7 to 9 ft prevail. For the forecast, the cold front will linger across the NW waters. Fresh to strong southerly winds and moderate to rough seas will continue ahead of the front through tonight. The NW swell will impact the waters N of 10N and W of 130W through midweek. A surface low may develop along the frontal boundary the middle of the week, bringing another round of fresh to strong southerly winds and rough seas. Combined swell generated from the Gulf of Tehuantepec and Gulf of Papagayo gap wind events will bring rough seas to the waters E of 112W. This NE swell will spread rough seas westward across the waters S of 10N and E of 125W through Thu. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC241008_C_KWBC_20260224100900_29294990-8555-TWDEP.txt ****0000006127**** AXPZ20 KNHC 241008 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Tue Feb 24 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.
