--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-08-05 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC050145_C_KWBC_20260805014641_49676782-170-TWDEP.txt ****0000003423**** AXPZ20 KNHC 050145 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Wed Aug 5 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 0130 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 80W, north of 03N, 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 98W, 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 120W, moving westward at around 10 kt. Nearby convection is discussed in the ITCZ/Monsoon Trough section below. The axis of a tropical wave is near 132/133W, from 02N to 19N, moving westward at 10 kt. Nearby convection is discussed in the ITCZ/Monsoon Trough section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 06N97W to 13N130W to 09N133W. The ITCZ extends from 09N133W to 09N140W. Numerous moderate to isolated strong convection is noted from 02N to 10N east of 100W. Scattered moderate convection is active from 04N to 15N between 104W and 131W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh winds prevail over the Gulf of California, with slight seas. Moderate or weaker winds, and moderate seas, prevail over the open waters off Mexico. 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 fresh winds over the northern Gulf of California through Wed. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. 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, with strong winds and occasional rough seas at night the second half of the 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... Northerly swell is bringing rough seas to the waters N of 29N between 125W and 130W. Elsewhere over the discussion waters, gentle to moderate winds and moderate seas prevail. For the forecast, the rough seas in northerly swell will subside this evening. Southerly swell will build northward to 03N and west of 105W starting tonight and Wed. Seas may build to 8 ft in the tradewind zone in the western waters late this week. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC050744_C_KWBC_20260805074510_47448518-155-TWDEP.txt ****0000003271**** AXPZ20 KNHC 050744 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed Aug 5 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.
