--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-03-26 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC260406_C_KWBC_20260326040632_16515500-152-TWDEP.txt ****0000003728**** AXPZ20 KNHC 260406 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Thu Mar 26 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 surface trough extends from 07N08W to 07N85W to 05N88W, where it transitions to the ITCZ and continues to 05N118W and beyond 03N140W. Scattered moderate convection is from 01N to 07N between 85W and 110W, and from 02N to 06N between 126W and 138W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak pressure gradient across the region is maintaining light to gentle NW winds and slight to moderate seas across the Baja California offshore waters, except locally moderate to fresh winds over the coastal waters between Punta Eugenia and Cabo San Lazaro. In the Tehuantepec region, fresh to strong N to NE winds continue to pulse over the waters N of 14N where seas are 7 ft. Light to gentle winds and slight to moderate seas are ongoing elsewhere, including the Gulf of California. For the forecast, light and variable winds will prevail over the offshore waters through the forecast period. Northwest swell will build seas to rough north of Punta Eugenia Thu through Fri night before subsiding. Fresh to strong north gap winds in the Gulf of Tehuantepec will pulse nightly through Sat with rough seas. Gale-force northerly winds will develop in the Gulf of Tehuantepec Sat night through Sun night driven by the passage of a cold front across the Gulf of America. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE to E winds prevail in the Gulf of Papagayo region along with moderate seas. Farther east, moderate northeast winds are in the Gulf of Panama reaching southward to near 06N with moderate seas. Elsewhere, light to gentle winds and slight to moderate seas prevail. For the forecast, the fresh to strong northeast winds in the Gulf of Papagayo region will continue to pulse nightly going into the upcoming weekend along with moderate to rough seas. Moderate to fresh northeast winds will pulse in the Gulf of Panama during this time. Gentle breezes and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... The pressure gradient between modest high pressure north of 16N and west of 115W, and lower pressure near the ITCZ is currently sustaining moderate trades from 04N to 14N between 110W and 140W, and from 04N to 10N between 97W and 110W. Moderate seas prevail across this area, with max of 7 ft mainly W of 130W. Elsewhere, latest scatterometer satellite data indicates light to gentle northeast to east winds. Seas are 4 to 6 ft elsewhere primarily due to a long-period northwest to north swell. The tail-end of a stationary front just touches 30N140W, and stretches well southwestward from there. For the forecast, fresh to strong northeast to east winds will develop north of 26N and west of 119W Thu through Fri as the pressure gradient tightens between a ridge building southward across the north-central waters, and a low pressure system, with attendant trough lifting northward west of the area near 145W. Seas are expected to build to rough over this part of the area. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC260956_C_KWBC_20260326095734_16515500-164-TWDEP.txt ****0000003596**** AXPZ20 KNHC 260956 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Thu Mar 26 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 surface trough extends from 07N08W to 07N85W to 05N88W, where it transitions to the ITCZ and continues to 05N118W and beyond 03N140W. Scattered moderate convection is from 01N to 07N between 85W and 110W, and from 02N to 06N between 126W and 138W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Recent scatterometer data show moderate to locally fresh NW winds across the Baja California offshore waters, being the highest winds over the coastal waters between Punta Eugenia and Cabo San Lazaro. Altimeter data show moderate seas to 5 ft over these waters. In the Tehuantepec region, fresh to near gale force N to NE winds continue to pulse over the waters N of 13N where seas are 7 to 8 ft. Light to gentle winds and slight to moderate seas are ongoing elsewhere, including the Gulf of California. For the forecast, light to gentle variable winds will prevail over much of the offshore waters through Mon night. Northwest swell will build seas to rough north of Punta Eugenia today through Fri night before subsiding. Fresh to near gale force N to NE gap winds in the Gulf of Tehuantepec will pulse through Mon night, except for gale-force N winds forecast to develop Sat through Sun driven by the passage of a cold front across the Gulf of America. Moderate to rough seas will become very rough during the peak winds period Sat and Sun. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE winds are ongoing in the Papagayo region along with slight to moderate seas. In the Gulf of Panama, N to NE winds are moderate to fresh with slight to moderate seas. Elsewhere, light to gentle winds and slight to moderate seas prevail. For the forecast, fresh to strong NE winds in the Gulf of Papagayo region will continue to pulse through Mon night with moderate to rough seas. Moderate to fresh northeast winds will pulse in the Gulf of Panama with moderate seas through Mon night. Gentle breezes and slight to moderate seas will prevail elsewhere through the forecast period. ...REMAINDER OF THE AREA... The pressure gradient between a 1036 mb high pressure north of the region and a low pressure west of 140W is supporting a broad area of moderate to fresh NE to E winds N of 25N and W of 120W along with moderate to rough seas in NW swell. Moderate or weaker winds and moderate seas in mixed swell are ongoing elsewhere. For the forecast, fresh to locally strong NE to E winds will develop north of 26N and west of 119W today through Fri as the pressure gradient tightens between a ridge building southward across the north-central waters, and a low pressure system, lifting northward west of the area. Rough seas over the northern waters are forecast to subside below 8 ft Sat. Otherwise, a weak front will approach the far NW waters on Mon, however little impact on winds or seas is foreseen. $$ Ramos ########################### END OF MESSAGE SET ############################
