The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...SPECIAL FEATURES... Hurricane Genevieve is centered near 19.6N 120.8W at 30/0300 UTC, moving west-northwest at 8 kt. Estimated minimum central pressure is 970 mb. Maximum sustained wind speed is 85 kt with gusts to 105 kt. Peak seas are near 35 ft or 10.5 m. Numerous moderate convection is within 150 nm of the center. Genevieve is moving toward the west-northwest. This general motion with a slight increase in forward speed is expected during the next several days. Steady weakening is expected during the next couple of days, and Genevieve is forecast to become post- tropical this weekend. Swells generated by Genevieve are affecting portions of the Baja California Peninsula and Southern California. These swells will persist for the next several days and are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. Please read the latest HIGH SEAS FORECAST issued by the National Hurricane Center at website - https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest Genevieve NHC Forecast/Advisory and Public Advisory at www.hurricanes.gov for more details. ...TROPICAL WAVES... A tropical wave is along 94W, extending from just NW of the Galapagos Islands to the Guatemala-Mexico border, moving west at 15 to 20 kt. Scattered moderate convection is noted from 10N to 13N between 93W and 96W. A tropical wave is along 109W, from 03N to 18N, drifting W at around 5 kt. Scattered moderate convection is noted from 10N to 18N between 102W and 112W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N80W to 09N89W to 09N104W to 14N114W. The ITCZ extends from 11N123W to beyond 08N140W. Nearby convection is primarily associated with the tropical waves described in the above section. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please refer to the Tropical Waves sections above for information about convection in the region. Hurricane Genevieve is well west of the Revillagigedo Islands moving away from the region. Associated rough seas impacting the far western offshore waters of Baja California will subside Thu. Elsewhere, moderate or weaker winds prevail. Seas are slight in the Gulf of California and moderate in the remaining offshore waters. For the forecast, fresh northerly winds are likely in the Gulf of Tehunatepec Thu and Fri nights. Elsewhere, areas of fresh mainly westerly gap winds are expected through Thu night nearshore Baja California as high pressure builds southward to the west of the Baja California Peninsula. Moderate to locally fresh SE to S winds may pulse in the northern Gulf of California beginning this weekend. Looking ahead, rough northerly seas may briefly build south of 30N into the waters off Baja California Norte by the end of the weekend into early next week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Please refer to the Tropical Wave sections above for information about convection in the region. High pressure northeast of the area is forcing fresh to strong easterly gap winds and resultant seas of 5 to 7 ft across the Gulf of Papagayo region, with moderate to locally fresh northerly gap winds in the Gulf of Panama. Elsewhere, light to gentle winds and moderate seas prevail. For the forecast, fresh to strong NE to E gap winds will pulse across the Papagayo region through Sun, with occasionally rough seas. Pulsing moderate to locally fresh N winds are expected in the Gulf of Panama tonight and Thu night. Southerly winds may freshen offshore southern Colombia and from Ecuador to the Galapagos Islands Thu night and Fri. 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... Please refer to the Special Features section for information on Hurricane Genevieve. For waters not being impacted by Hurricane Genevieve, high pressure is centered just northwest of the area. The pressure pattern between the high and Genevieve is supporting moderate to fresh NE trades from offshore southern California SW to about 12N140W. Seas in this region have built to 6 to 9 ft. Moderate to locally fresh SE winds are found south of the Equator and west of 100W. Moderate or weaker winds are elsewhere. Moderate seas dominate the the remaining waters away from Genevieve. Hurricane Genevieve is near 19.6N 120.8W at 8 PM PDT, and is moving west-northwest at 8 kt. Maximum sustained winds are 85 kt with gusts to 105 kt, and the minimum central pressure is 970 mb. For the forecast, Genevieve will move to 20.1N 122.6W Thu morning, 20.8N 125.0W Thu evening, then weaken to a tropical storm near 21.6N 127.5W Fri morning. Tropical Storm Genevieve 22.3N 130.3W Fri evening, 23.1N 133.0W Sat morning, and 23.9N 135.9W Sat evening. Genevieve will become post-tropical as it moves into the Central Pacific basin late Sun. Away from Genevieve, little change in marine conditions is forecast into the weekend. Fresh and rough northerly swell off California may push southward into the waters off Baja California Norte north of 27N and east of 130W by the end of the weekend into early next week. $$ Konarik ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC300904_C_KWBC_20260730090511_47448518-9645-TWDEP.txt ****0000006338**** AXPZ20 KNHC 300904 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Thu Jul 30 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.
