--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-02-23 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC230408_C_KWBC_20260223040851_29294990-8483-TWDEP.txt ****0000006893**** AXPZ20 KNHC 230408 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Feb 23 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 0350 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Storm Warning: Strong gale-force winds are ongoing across the Gulf of Tehuantepec and downwind to about 12N. High pressure building behind a cold front, currently moving across the SE Gulf of America, will provide a very tight pressure gradient over the area, and bring an increase in winds funneling into the Gulf of Tehuantepec. Winds are forecast to increase to storm-force shortly tonight, with seas building to 20 ft. Storm-force winds will continue through Mon night and seas will build to 24 ft. Afterward, winds will diminish to strong gale force speeds Tue morning and gradually diminish 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 reaching as far west as 105W, and as far south than 04N by Mon night. 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. Winds are forecast to diminish below gale force early on Wed. Gulf of Papagayo Gale Warning: High pressure over Central America will support fresh to locally strong NE to E gap winds over the Papagayo region through tonight. These winds are forecast to strengthen to 25 to 30 kt on Mon, with seas building to 8 to 10 ft. Minimal gale conditions and rough seas are expected Tue morning through Wed morning as the pressure gradient tightens over the NW Caribbean. 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). The region should see the heaviest accumulations tonight through Mon. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 09N85W to 01N105W. The ITCZ begins near 03S103W to 01S130W to 02N140W. Scattered moderate convection is within 90 nm either side of the trough and across the Panama offshore waters. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the SPECIAL FEATURES section for information on a STORM WARNING for the Gulf of Tehuantepec. Strong high pressure centered over the Great Basin provides for fresh to strong NW winds across the entire Gulf of California. Seas are near 7 ft in the central and southern part of the Gulf. A ridge extending from a 1024 mb high pressure located near 31N122W dominates the offshore forecast waters of Baja California supporting mainly moderate NW winds with moderate seas. Elsewhere across the Mexican offshore waters, outside of the Tehuantepec region, mainly light to gentle winds and moderate seas prevail. For the forecast, high pressure over the Great Basin will continue to induce fresh to strong NW winds across the central and southern parts of Gulf of California tonight into Mon morning with seas in the 5 to 7 ft range. Winds will diminish to moderate to fresh speeds in the afternoon with seas gradually subsiding. A strong gap wind event is ongoing across the Tehuantepec region. Please, see the Special Features section for more information. ....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. Fresh to strong gap winds are blowing across the Gulf of Papagayo and downwind to about 88W, with seas currently to 4 to 6 ft. Moderate to fresh N to NE winds are ongoing in the Gulf of Panama with seas to 4 ft. Elsewhere, light to gentle winds and slight seas prevail. For the forecast, high pressure over Central America will support fresh to locally strong NE to E gap winds over the Papagayo region through tonight. These winds are forecast to strengthen to 25 to 30 kt on Mon, with seas building to 8 to 10 ft. Minimal gale conditions and rough seas are expected Tue morning through Wed morning as the pressure gradient tightens over the NW Caribbean. This will also support fresh to locally strong NE winds downwind of the Gulf of Panama and just S of the Azuero Peninsula to about 03N Mon night into Tue. Seas to around 8 ft will likely be associated with these winds. In addition, the large extent 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 tonight through Mon night. Rough seas will continue to propagate across these waters through Tue night. ...REMAINDER OF THE AREA... A cold front is NW of the area preceded by a surface trough. High pressure of 1024 mb situated near 31N122W dominates the waters N of 18N and W of 110W, including the Revillagigedo Islands. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ supports an area of fresh trade winds from 07N to 22N between 116W and 130W. Seas of 6 to 8 ft in decaying long period NW swell, are noted S of 20N and W of 120W. Elsewhere, winds are moderate or weaker and seas are 4 to 6 ft. For the forecast, the cold front will move slowly across the NW waters, and extend from 30N138W to 28N140W tonight. Fresh to strong southerly winds and moderate to rough seas are expected ahead of the front tonight through Mon night. A new set of long period NW swell will follow the front, building seas to 14 ft over the NW corner of the forecast region on Mon. In the meantime, high pressure will continue to dominate the waters between the front and Baja California Norte. Looking ahead, a surface low may develop along the front near 30N140W on Wed, bringing another round of fresh to strong southerly winds and rough seas. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC231006_C_KWBC_20260223100653_29294990-8495-TWDEP.txt ****0000006994**** AXPZ20 KNHC 231006 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon Feb 23 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.
