The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0330 UTC. ...TROPICAL WAVES... A tropical wave is analyzed along 84W north of 06N, moving westward around 10-15 kt. No significant convection is noted with this tropical wave. A tropical wave is analyzed along 124W from 02N to 16N, moving quickly westward at around 15-20 kt. Any nearby convection is described in the monsoon trough/ITCZ section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 09N85W to 07N90W. The ITCZ extends from 07N90W to 09N120W, and from 08N125W to beyond 07N140W. Scattered moderate convection is active from 05N to 13N between 115W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends from 1026 mb high pressure near 35N140W southeastward to off the coast of Baja California then to the Revillagigedo Islands. Recent scatterometer satellite data showed moderate to fresh NE winds off the coast of Baja California north of Cabo San Lazaro, between the ridge and troughs over northwest Mexico. Seas in this area are 5-7 ft. Gentle to moderate breezes are noted elsewhere with 4-6 ft seas primarily in SW swell. Clusters of showers and thunderstorms are active along the coast of southern Mexico between Puerto Angel and Manzanillo. For the forecast, the ridging will hold across the offshore waters of Baja California through Wed night, with the resultant gradient leading to moderate to fresh NW winds over these same waters, locally strong to the north of Punta Eugenia through Tue night. Moderate to fresh gap winds in the Gulf of Tehuantepec will pulse at fresh to strong speeds at night into the mornings through the rest of the week and into the weekend, with seas to rough at times. Little change in winds is forecast elsewhere, except increasing and pulsing to fresh to strong in the central and northern Gulf of California by the end of the week as the gradient tightens there. Fresh NW swell off California will push southward off Baja California Norte late Tue night into early Wed, continuing through Fri. Moderate seas are forecast elsewhere. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A recent scatterometer satellite pass confirmed a plume of fresh NE to E gap winds persist across the Papagayo region and extend offshore to near 90W, where seas are 5-7 ft. Moderate to locally fresh winds are elsewhere to the N of 09N. Moderate SE winds are offshore Ecuador to the Galapagos Islands, where seas are 6-9 ft in SW swell. Light to gentle winds are across the remainder of the waters, along with 4-7 ft mainly in SW swell. For the forecast, fresh to strong NE-E gap winds will pulse in the Gulf of Papagayo region into early Thu, then moderate to fresh thereafter. Moderate to fresh N-NE winds will pulse in the Gulf of Panama through Tue night. Little change in winds is forecast elsewhere through the week. Cross equatorial SW swell will move through the waters off Ecuador and the Galapagos Islands through early Wed, with seas peaking around 9 ft. The combination of the southerly swell with shorter period seas associated with gap winds will allow combined seas to build to a peak of about 8 ft offshore of northern Central America Tue through Wed with mainly moderate seas otherwise. ...REMAINDER OF THE AREA... A trough, the remnant of Douglas, is along 133W from 22N to 27N. A recent scatterometer satellite pass indicated fresh NE winds within 60 nm west of this trough. Elsewhere, a broad ridge dominates the waters north of 15N, supporting moderate NE winds and 5-7 ft seas in a mix of N and SW swell. Fresh NE winds and seas to 8 ft are also noted farther south ahead of the tropical wave near 124W, specifically from 09N to 13N between 120W and 135W. Gentle to moderate breezes are noted elsewhere. Long period SW swell to 8 ft is reaching 08N between 90W and 130W. Combined seas are 5-7 ft elsewhere. For the forecast, the remnant trough of Douglas will continue drifting westward through the rest of the week. The ridge will build ESE through Wed night, with the gradient between it and the remnant Douglas trough leading to a solid area of fresh trades west of 120W along with seas of 7-8 ft. Large southerly swell with seas up to 9 ft will continue impacting the waters S of 06N through mid-week before gradually decaying. Large northerly swells off California will build seas to around 9 ft offshore Baja California Norte by mid-week, lingering through the end of the work week. Meanwhile, the tropical wave will continue moving westward with scattered moderate convection. $$ Christensen ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC070918_C_KWBC_20260707091840_9109880-7711-TWDEP.txt ****0000005396**** AXPZ20 KNHC 070918 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Tue Jul 7 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 0900 UTC. ...TROPICAL WAVES... A tropical wave is analyzed along 85W north of 06N, moving westward around 10-15 kt. No significant convection is noted with this tropical wave. A tropical wave is analyzed along 125W from 02N to 16N, moving quickly westward at around 20-25 kt. Any nearby convection is described in the monsoon trough/ITCZ section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 08N78W to 09N95W to 05N90W. The ITCZ extends from 05N90W to 07N120W to 05N125W, and from 06N130W to 08N135W. Scattered moderate convection is active from 03N to 13N between 105W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends from 1025 mb high pressure near 35N140W southeastward to off the coast of Baja California then to just west of the Revillagigedo Islands. Scattered showers and thunderstorms have been active over the past several hours over southern Sonora and northern Sinaloa have resulted in fresh to strong winds over the southern and central Gulf of California along the eastern shore. Moderate to fresh N to NE winds and 5-7 ft seas are occurring off Baja California Norte between the ridge and lower pressure over northwest Mexico. Moderate E winds and 6-7 ft seas are noted off western Oaxaca beyond 90 nm offshore, and north of lowering pressure over the deep tropics. Gentle to moderate breezes and 4-6 ft are noted elsewhere, except 1-3 ft seas in the Gulf of California. For the forecast, the ridging will persist off Baja California through mid week, with lower pressure inland over northwest Mexico. This pattern will support fresh to occasionally strong NW winds off Baja California Norte through Wed night, with rough seas in NW swell near Guadalupe Island. These winds will diminish Thu, as low pressure moves off the Pacific into the lower Colorado River Valley. This will result in fresh to strong S winds and rough seas late Thu into Fri over the northern Gulf of California. Looking ahead, lowering pressure across the tropical eastern Pacific will induce moderate to fresh N gap winds and occasionally rough seas across the Gulf of Tehuantepec later in the week. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A recent scatterometer satellite pass from 05 UTC confirmed a plume of fresh to strong NE to E gap winds persist across the Papagayo region and extend offshore to near 90W, where seas are 5-7 ft. Moderate to locally fresh winds are elsewhere to the N of 09N. Moderate SE winds are offshore Ecuador to the Galapagos Islands, where seas are 6-9 ft in SW swell. Light to gentle winds are across the remainder of the waters, along with 4-7 ft mainly in SW swell. For the forecast, fresh to strong NE-E gap winds will pulse in the Gulf of Papagayo region into early Thu, then moderate to fresh thereafter. Cross equatorial SW swell will move through the waters off Ecuador and the Galapagos Islands through early Wed, with seas peaking around 9 ft. The combination of the southerly swell with shorter period seas associated with gap winds will allow combined seas to build to a peak of about 8 ft offshore of northern Central America through Wed. Gentle to moderate breezes and slight to moderate seas will persist elsewhere. ...REMAINDER OF THE AREA... A trough, the remnant of Douglas, is along 133W/134W from 21N to 28N. A recent scatterometer satellite pass from 0630 UTC indicated fresh NE winds within 60 nm northwest of this trough. Elsewhere, a broad ridge dominates the waters north of 15N, supporting moderate NE winds and 5-7 ft seas in a mix of N and SW swell. Fresh NE winds and seas to 9 ft are also noted farther south ahead of the tropical wave near 125W, specifically from 10N to 15N between 125W and 135W. Scattered showers and thunderstorms are ongoing near a surface trough along 137W from 03N to 10N. Recent scatterometer satellite data indicate fresh to strong winds are within 90 nm of the trough, and rough seas are likely accompanying the strong winds. Gentle to moderate breezes are noted elsewhere. Long period SW swell to 8 ft is reaching 08N between 90W and 130W. Combined seas are 5-7 ft elsewhere. For the forecast, strong winds and rough seas will follow the trough near 137W as it moves west of 140W tonight. Strong winds and rough seas will also accompany the tropical wave near 125W at it moves westward at 20 to 25 kt through 135W by Wed night and past 140W by late Fri. Farther north, swell of 8-9 ft will persist north of 25N east of 125W through Fri. Farther south, large swell to 7-8 ft will persist south of 01N between 95W and 120W through Fri. $$ Christensen ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC071425_C_KWBC_20260707142542_9109880-7729-TWDEP.txt ****0000005618**** AXPZ20 KNHC 071425 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Tue Jul 7 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.

The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 1900 UTC. ...TROPICAL WAVES... A tropical wave is analyzed along 81W to the north of 06N, moving westward around 15 kt. Any nearby convection is described in the monsoon trough/ITCZ section below. A tropical wave is analyzed along 129W from 02N to 16N, moving westward at around 10 kt. Any nearby convection is described in the monsoon trough/ITCZ section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 10N75W to 06N91W. The ITCZ extends from 06N91W to 09N106W to 05N120W to 07N128W, then resumes W of a tropical wave from 07N131W to 09N138.5W. Scattered moderate convection is active from 02.5N to 05.5N between 80W and 84W, and from 08N to 13N between 135W and 140W. Scattered moderate isolated strong convection is active from 04N to 09N between 95W and 115W, and from 03N to 14N between 116W and 134W. Similar convection is active from 12N to 14N between 98W and 103W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends across the waters W of 110W. Surface troughing is found from NW to SE across the Gulf of California. This pressure pattern supports moderate to fresh winds offshore Baja California mainly from Punta Eugenia northward. A small plume of fresh to strong gap winds is found in the Gulf of Tehuantepec. Winds are moderate or weaker elsewhere. Seas are mainly 4-7 ft across the offshore waters in S to SW swell, except mixed with NW swell offshore Baja California. Seas are 1-3 ft in the Gulf of California N of the entrance. Active convection is present offshore southern and SW Mexico as described above. For the forecast, the ridging will persist off Baja California through mid week, with lower pressure inland over northwest Mexico. This pattern will support fresh to occasionally strong NW winds off Baja California Norte through Wed night, with rough seas in NW swell near Guadalupe Island. These winds will diminish Thu, as low pressure moves off the Pacific into the lower Colorado River Valley. This will result in fresh to strong S winds and rough seas late Thu into Fri over the Gulf of California. Fresh to strong northerly gap winds will pulse in the Gulf of Tehuantepec through the week. Looking ahead, lowering pressure across the tropical eastern Pacific will induce fresh to strong winds and occasionally rough seas offshore southern Mexico by the weekend. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A wide plume of fresh to strong NE to E gap winds persist across the Papagayo region and extend offshore to near 93W, where seas are 6-9 ft.

Moderate SE winds are across the offshore waters of the Galapagos Islands, where seas are 6-9 ft in SW swell. Light to gentle winds are across the remainder of the waters, along with 4-7 ft mainly in SW swell. For the forecast, fresh to strong NE-E gap winds will pulse in the Gulf of Papagayo region into early Thu along with rough seas, then moderate to fresh winds thereafter. Cross equatorial SW swell will move through the waters off Ecuador and the Galapagos Islands through Wed, with seas peaking around 9 ft. The combination of the southerly swell with shorter period seas associated with gap winds will allow combined seas to build to a peak of about 8 ft offshore of northern Central America through Wed. Gentle to moderate breezes and slight to moderate seas will persist elsewhere, with locally fresh N winds in the Gulf of Panama tonight. Looking ahead, lowering pressure across the tropical eastern Pacific will induce fresh to strong winds and occasionally rough seas offshore El Salvador and Guatemala by the end weekend. ...REMAINDER OF THE AREA... A trough, the remnant of Douglas, is along 136W from 23N to 29N. Elsewhere, a broad ridge dominates the waters north of 16N, supporting moderate NE winds and 5-7 ft seas in a mix of N and SW swell. Fresh NE winds and seas to 9 ft are also noted farther S ahead of the tropical wave near 129W, specifically from 10N to 20N between 125W and 135W. Scattered showers and thunderstorms are ongoing near a surface trough between 136W and 140W along with fresh to strong winds within 90 nm of the trough. Rough seas are likely accompanying the strong winds. Gentle to moderate breezes are noted elsewhere. Long period SW swell to 8 ft is reaching 05N between 90W and 120W. Combined seas are mainly 5-7 ft elsewhere. For the forecast, strong winds and rough seas will follow the trough near 140W until it moves W of the discussion waters overnight. Strong winds and rough seas will also accompany the tropical wave near 129W at it moves westward at 15 to 20 kt, reaching 135W by Wed night, and past 140W by late Fri. Farther N, swell of 8-9 ft will persist north of 25N to the E of 125W through Fri.
