--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-02-20 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC200406_C_KWBC_20260220040630_29294990-8279-TWDEP.txt ****0000004180**** AXPZ20 KNHC 200406 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Fri Feb 20 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. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 10N85W to 01N102W. A second surface trough extends from 06N77W to 08N78W. The ITCZ extends from 00N107W to 01N88W. Scattered moderate convection is noted from 00N to 09N between 77W and 92W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds are occurring just west of Baja California with the rest of forecast waters experiencing moderate or weaker winds. Large, medium-period NW swell with seas of at 8-11 ft are occurring west of the Baja California peninsula. Elsewhere, seas are 3-7 ft over the SW Mexico waters and 1-3 ft over the Gulf of California. For the forecast, fresh to strong SW winds over the N Gulf of California ahead of a cold front will diminish on Fri afternoon. The cold front will also accelerate NW winds to fresh and locally strong along the Pacific waters west of the Baja California peninsula through Fri night. High pressure building in behind the front will induce moderate to fresh NW winds across the entire Gulf of California Sat into early Mon. Looking ahead, a vigorous cold front pushing across the Gulf of America will induce a strong gale-force gap wind event over the Gulf of Tehuantepec Sun into at least Tue night. Very large seas are likely to accompany this gap wind event, propagating well away from the source region. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE winds continue over the Papagayo region with seas 4-6 ft. Elsewhere, winds are moderate or weaker with seas 3-5 ft. Light to gentle variable winds are ongoing elsewhere. Otherwise, scattered moderate convection is offshore Panama, Colombia and Ecuador. For the forecast, high pressure over Central America will be forcing fresh to strong NE to E gap winds over the Papagayo region for the next several days. These winds may strengthen to near gale conditions on Tue and Tue night. Looking ahead, a strong gale- force gap wind event over the Gulf of Tehuantepec will induce fresh to strong N to NE winds and large to very large NW swell over the Guatemala and El Salvador waters on Mon and Tue. ...REMAINDER OF THE AREA... Surface ridging extends from a 1035 mb high centered at 37N153W SE to the Revillagigedo Islands. The pressure gradient from this high to lower pressure over the ITCZ is forcing fresh to strong trades from 07N-22N west of 118W. Seas are 8-12 ft over the area with these fresh to strong trades in mixed wind waves and N swell. Farther north, large, medium-period NW swell of 8-11 ft seas is across the subtropical waters. Elsewhere, winds are moderate or weaker and seas are 4-7 ft. Scattered moderate convection is occurring from 16N-26N west of 135W, due to a surface trough just west of our 140W border. An approaching extratropical cyclone to our N border tomorrow and Sat will weaken the pressure gradient over the tropics, reducing the trades down to moderate for the next few days. The high seas associated with these trades and large N swell will also steadily diminish by Sat. The large NW swell along our N border will also fade while pushing equatorward, dropping below 8 ft by Sat afternoon. Looking ahead, a cold front associated with the extratropical cyclone will reach our NW corner waters Mon with winds only moderate to fresh. However, the system will also advect large to very large NW swell over our NW waters on Mon and Tue, primarily west of 130W. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC200942_C_KWBC_20260220094222_16515500-7943-TWDEP.txt ****0000004179**** AXPZ20 KNHC 200942 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Fri Feb 20 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 0930 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 11N86W to 02S103W. A second surface trough extends from 06N77W to 00N88W. The ITCZ extends from 02S103W to 02S125W to 00N140W. Scattered moderate convection is noted from 03S to 08N between 77W and 97W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds are occurring just west of Baja California with the rest of forecast waters experiencing moderate or weaker winds. Large, medium-period NW swell with seas of at 8-10 ft are occurring west of the Baja California peninsula. Elsewhere, seas are 3-7 ft over the SW Mexico waters and 1-3 ft over the Gulf of California, except to 6 ft N of 30N. For the forecast, fresh to strong SW winds over the N Gulf of California ahead of a cold front will diminish by this afternoon. The cold front will also continue to accelerate NW winds to fresh and locally strong speeds along the Pacific waters west of the Baja California peninsula through tonight. High pressure building in behind the front will induce fresh to strong NW winds across the entire Gulf of California Sat into Mon. Looking ahead, a vigorous cold front pushing across the Gulf of America will induce a strong gale-force gap wind event over the Gulf of Tehuantepec Sun into early Tue night. Very large seas are likely to accompany this gap wind event, propagating well away from the source region. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE winds continue over the Papagayo region with seas 4-5 ft. Elsewhere, winds are light to gentle with seas 3-4 ft. Otherwise, scattered moderate convection is offshore Panama, Colombia and Ecuador. For the forecast, high pressure over Central America will be forcing fresh to strong NE to E gap winds over the Papagayo region through the middle of next week. These winds may strengthen to near gale conditions on Mon night through Wed morning. Looking ahead, a strong gale-force gap wind event over the Gulf of Tehuantepec will induce fresh to strong N to NE winds and large to very large NW swell over the Guatemala and El Salvador waters on Mon through Tue night. ...REMAINDER OF THE AREA... Surface ridging extends from a 1033 mb high centered at 36N153W SE to the Revillagigedo Islands. The pressure gradient from this high to lower pressure over the ITCZ is forcing fresh to strong trades from 06N to 21N west of 124W. Seas are 8-11 ft over the area with these fresh to strong trades in mixed wind waves and N swell. Farther north, large, medium-period NW swell of 8-11 ft seas is across the subtropical waters. Elsewhere, winds are moderate or weaker and seas are 4-7 ft. Scattered moderate convection is occurring from 20N-25N west of 135W, due to a surface trough along 146W. An approaching extratropical cyclone to our N border today and Sat will weaken the pressure gradient over the tropics, reducing the trades down to moderate for the next few days. The high seas associated with these trades and large N swell will also steadily diminish by Sat. The large NW swell along our N border will also fade while pushing equatorward, dropping below 8 ft by Sat afternoon. Looking ahead, a cold front associated with the extratropical cyclone will reach our NW corner waters Mon with winds only moderate to fresh. However, the system will also advect large to very large NW swell over our NW waters on Mon and Tue, primarily west of 130W. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC201603_C_KWBC_20260220160324_16515500-7956-TWDEP.txt ****0000005902**** AXPZ20 KNHC 201603 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Fri Feb 20 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.

Based on 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: The next gap wind event across the Tehunatepec region is expected on Sun as a ridge builds across the eastern slopes of the Sierra Madre Mountains in Mexico, behind a cold front moving across the Gulf of America. Wind are forecast to suddenly increase to 35 to 40 kt, with seas building to 9 to 12 ft on Sun. Then, winds will further increase to near storm force by Sun evening, with seas building to 12 to 18 ft. Large seas generated from this strong gap wind event will spread well away from the Tehuantepec area, with seas 8 ft or greater reaching as far west as 105W by Mon night. Marine interests transiting across or in the Gulf of Tehuantepec Sun evening through Tue should be aware of this upcoming 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. Please read the latest NWS High Seas issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 11N86W to 02S103W. The ITCZ is S of the Equator and continues from 02S103W to 03S120W to 01S140W. A second surface trough is analyzed from a 1008 mb low pressure located over northern Colombia near 10N75W to 01N90W. Scattered moderate convection is noted from 05N to 08N between 81W and 90W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A Gale Warning has been issued for the Gulf of Tehuantepec. Please, see the Special Features section for more details. A cold front extends across the northern Gulf of California into Baja California Norte, then continues westward to 28N120W to 30N131W. Fresh to locally strong NW winds and rough seas are noted N of Punta Eugenia, and in the wake of the front. Elsewhere across the offshore forecast waters of Baja California, moderate to locally fresh NW winds and moderate to rough seas in NW swell prevail. In the Gulf of California, fresh to strong SW winds are ahead of the cold front affecting mainly the waters from 29.5N to 30.5N. Seas are 5 to 7 ft within this winds. Gentle to moderate W to NW winds and moderate seas dominate the remainder of the Mexican offshore waters. For the forecast, the fresh to strong SW winds over the N Gulf of California ahead of a cold front will diminish by this afternoon. The cold front will move southward today while dissipating. High pressure building in behind the front will induce fresh to strong NW winds across most of the Gulf of California Sat into Mon. Looking ahead, a vigorous cold front pushing across the Gulf of America will induce a strong gale-force gap wind event across the Tehuantepec region Sun through Tue. Very large seas are likely to accompany this gap wind event, propagating well away from the source region. Please, see the Special Features section for more details. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE winds continue over the Papagayo region with seas of 4 top 6 ft. Elsewhere, light to gentle with seas 3 to 4 ft are observed. Otherwise, scattered moderate convection is offshore western Panama. For the forecast, high pressure over Central America will support fresh to locally strong NE to E gap winds over the Papagayo region through Sun night. These winds are forecast to strengthen on Mon, to 25 to 30 kt with seas building to 8-10 ft. Minimal gale conditions could be possible Tue morning through Wed morning. Looking ahead, seas generated in the Tehuantepec region are forecast to propagate across the offshore waters of Guatemala and El Salvador Sun night through Tue night with seas building to around 15 ft. ...REMAINDER OF THE AREA... A surface ridge extends from a 1032 mb high pressure centered N of the Hawaiian Islands to beyond the Revillagigedo Islands. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ supports fresh to strong trades from 08N to 21N W of 130W, and from 08N to 16N between 120W and 130W based on latest scatterometer data. Seas are 8 to 12 ft within these winds based on altimeter data. Farther north, long period NW swell of 8 to 11 ft seas is across the subtropical waters. Elsewhere, winds are moderate or weaker and seas are 4-7 ft. Scattered moderate convection is occurring from 20N-25N west of 135W, due to a surface trough along 146W. An approaching extratropical cyclone to our N border today and Sat will weaken the pressure gradient over the tropics, reducing the trades down to moderate for the next few days. The high seas associated with these trades and large N swell will also steadily diminish by Sat. The large NW swell along our N border will also fade while pushing equatorward, dropping below 8 ft by Sat afternoon. Looking ahead, a cold front associated with the extratropical cyclone will reach our NW corner waters Mon with winds only moderate to fresh. However, the system will also advect large to very large NW swell over our NW waters on Mon and Tue, primarily west of 130W. $$ GR ########################### END OF MESSAGE SET ############################
