The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0130 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 83W, north of 02N, moving westward at 10 to 15 kt. Nearby convection is discussed in the ITCZ/Monsoon Trough section below. The axis of a tropical wave is near 107W, moving westward at around 10 to 15 kt. Nearby convection is discussed in the ITCZ/Monsoon Trough section below. The axis of a tropical wave is near 125W, from 02N to 18N, moving westward around 10 kt. Nearby convection is discussed in the ITCZ/Monsoon trough section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N86W to 10N113W to 12N120W to 06N135W. The ITCZ extends from 06N135W to 06N140W. Scattered moderate and isolated strong convection is noted from 03N to 13N between 80W and 122W, and from 04N to 10N between 135W to 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gentle to moderate winds prevail across the region. Moderate seas dominate the open waters off Mexico, with slight seas in the Gulf of California. For the forecast, the pressure gradient between high pressure west of the area and lowering pressure over the Colorado River Valley will support fresh SW winds and building seas over the northern Gulf of California through the early part of the week. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. Long- period NW swell over the waters off Baja California Norte will start to subside Tue. Fresh to strong gap winds and building seas are expected across the Gulf of Tehuantepec toward the end of the week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh winds and moderate seas prevail over and downstream the Gulf of Papagayo. Gentle to moderate winds are found between the Galapagos Islands and Ecuador. Light to gentle winds and moderate seas are noted elsewhere. For the forecast, moderate to fresh winds will pulse across the Papagayo region tonight, and again by mid week with rough seas. Moderate or weaker winds and moderate seas in SW swell are expected across the remainder of the waters through the period. ...REMAINDER OF THE AREA... The remnant low of Genevieve is just crossing 140W. Strong to near gale force winds around this remnant low are over the forecast waters N of 25N and W of 138W. Elsewhere over the discussion waters, gentle to moderate winds and moderate seas prevail. For the forecast, large northerly swell off California will push southward into the waters off Baja California Norte north of 27N and east of 130W into early this week. New large southerly swell may build south of the Equator and west of 100W beginning Tue night. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC030735_C_KWBC_20260803073550_47448518-9971-TWDEP.txt ****0000003399**** AXPZ20 KNHC 030735 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon Aug 3 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.

Gentle to moderate winds prevail across the region. Moderate seas dominate the open waters off Mexico, with slight seas in the Gulf of California. For the forecast, the pressure gradient between high pressure west of the area and low pressure over the Colorado River Valley will support moderate to occasionally fresh winds over the northern Gulf of California through the early part of the week. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. Long- period NW swell over the waters off Baja California Norte will start to subside Tue. Fresh to strong gap winds and building seas are expected across the Gulf of Tehuantepec toward the end of the week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...

Moderate or weaker winds and moderate seas in SW swell are expected across the remainder of the waters through the period. ...REMAINDER OF THE AREA... Fresh to near gale force winds, and rough seas, are over the far NW portion of the discussion waters due to the remnant low of Genevieve, centered just west of the area. Elsewhere over the discussion waters, gentle to moderate winds and moderate seas prevail. For the forecast, large northerly swell will bring rough seas over the waters off Baja California Norte north of 27N and east of 130W through the early part of the week before subsiding. New large southerly swell may build south of the Equator and west of 100W beginning Tue night. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC031508_C_KWBC_20260803150830_49676782-48-TWDEP.txt ****0000004088**** AXPZ20 KNHC 031508 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Mon Aug 3 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 1200 UTC surface analysis and satellite imagery through 1505 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 87W, north of 02N, moving westward at 10 to 15 kt. A few showers are noted near the trough axis. The axis of a tropical wave is near 109W, moving westward at around 10 to 15 kt. A few showers are present near the trough axis. The axis of a tropical wave is near 127W, from 02N to 19N, moving westward around 10 kt. Scattered moderate to strong convection is observed from 03N to 17N and between 114W and 131W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 07N77W to 11N110W to 13N120W to 05N140W. Scattered moderate to isolated strong convection is occurring from 02N to 18N and east of 114W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The subtropical ridge in the NE Pacific is centered off the Pacific Northwest of the United States, allowing for a ridge to extend southeastward to the Revillagigedo Islands. The weak ridge supports mainly moderate or weaker winds and slight to moderate seas across much of the Mexican offshore waters, including the Gulfs of California and Tehuantepec. A subsiding northerly swell well west of Baja California Norte still produces seas to 8 ft to the northwest of Guadalupe Island. A few showers and isolated thunderstorms are noted off southern and SW Mexico. Gusty winds and suddenly higher seas are possible near the stronger storms. For the forecast, the pressure gradient between high pressure NW of the area and low pressure over the Colorado River Valley will support moderate to occasionally fresh winds over the northern Gulf of California through the early part of the week. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. Long-period NW swell over the waters off Baja California Norte will start to subside Tue. Fresh to strong gap winds and building seas are expected across the Gulf of Tehuantepec toward the end of the week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... High pressure north of the area continues to support moderate to locally fresh winds and moderate seas in the Gulf of Papagayo, extending downstream to about 90W. Gentle to moderate winds are found between the Galapagos Islands and Ecuador. Light to gentle winds and moderate seas are noted elsewhere. For the forecast, moderate to fresh winds will pulse across the Papagayo region, with occasionally strong winds pulsing by mid week. Moderate or weaker winds and moderate seas in SW swell are expected across the remainder of the waters through the period. ...REMAINDER OF THE AREA... The remnants of former Hurricane Genevieve continue to move away from the tropical eastern Pacific. However, moderate to fresh easterly winds and seas of 8-10 ft are still present north of 23N and west of 137W. In the northern waters, moderate northerly winds and seas of 7-9 ft are found north of 28N and east of 130W. High pressure dominates the remainder of the area, sustaining moderate or weaker winds and moderate seas. For the forecast, subsiding northerly swell will bring rough seas over the waters off Baja California Norte north of 27N and east of 130W through Tue. Southerly swell will build northward to 03N and west of 105W starting Tue night. Meanwhile, seas may build to 8 ft in the western trade waters late this week. $$ Delgado ########################### END OF MESSAGE SET ############################
