--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-08-04 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC040138_C_KWBC_20260804013957_47448518-46-TWDEP.txt ****0000003394**** AXPZ20 KNHC 040138 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Aug 4 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 93W, 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 115W, 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 128/129W, 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 08N109W to 13N125W to 08N133W. The ITCZ continues from 08N133W to beyond 07N140W. Scattered moderate to isolated strong convection is noted from 03N to 10N between 79W and 130W. ...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, occasionally locally strong, over the northern Gulf of California through Tue night. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. Northerly swell NW of Guadalupe Island will subside below 8 ft tonight. 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 pulsing at night starting Tue night. 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 has propagated into the northern waters, bringing rough seas to the waters N of 28N between 120W and 132W. Elsewhere over the discussion waters, gentle to moderate winds and moderate seas prevail. For the forecast, the northerly swell will bring rough seas over the waters off Baja California Norte north of 27N and east of 135W 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 tradewind zone in the western waters late this week. $$ AL ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC040735_C_KWBC_20260804073535_49676782-100-TWDEP.txt ****0000003217**** AXPZ20 KNHC 040735 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Tue Aug 4 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.
