Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Wed Jul 29 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 1300 UTC. ...SPECIAL FEATURES... Hurricane Genevieve is centered near 18.8N 119.2W at 29/1500 UTC, moving west-northwest at 7 kt. Estimated minimum central pressure is 960 mb. Maximum sustained wind speed is 100 kt with gusts to 120 kt. Peak seas are near 37 to 38 ft, or 11 m. Numerous moderate isolated strong convection is within 120 nm in the NE semicircle and 75 nm in the SW semicircle. Scattered to numerous moderate convection is noted elsewhere within about 180 nm in the E semicircle and 90 nm in the W semicircle. Genevieve is moving toward the west-northwest. This general motion with a slight increase in forward speed is expected during the next several days. Genevieve is a category 3 hurricane on the Saffir- Simpson Hurricane Wind Scale. Steady weakening is expected during the next few days, but Genevieve is forecast to remain a hurricane through Thu night. Swells generated by Genevieve are affecting portions of the Baja California Peninsula and will reach Southern California today. 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. A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_ep2.shtml?ripCurrents 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 88.5W, extending southward from the far NW Caribbean Sea southward along the coast of Belize to across portions of western Honduras and eastern El Salvador and into the eastern Pacific to around 03N. This wave is moving W at around 15 kt. Any nearby convection is described below with the ITCZ/monsoon trough. A tropical wave is along 107W, from 03N to 18N, moving very slowly W at around 5 kt. Any nearby convection is described below with the ITCZ/monsoon trough. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 1008 mb low pressure over northern Colombia at 09.5N75W to 08.5N84W to 05N92W to 13N115W. The ITCZ extends from 11N123W to beyond 07N140W. Scattered moderate isolated strong convection is noted from 02.5N to 07N between 77W and 81W, from 02.5N to 08N between 91W and 112W, from from 08N to 18.5N between 99W and 104W, from 12N to 25N between 105W and 109W, from 09N to 14N between 114W and 124W, and within 120 nm to 240 nm either side of the ITCZ between 124W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please refer to the Special Features section for information on Hurricane Genevieve with tropical storm force or greater winds just beyond the Baja California Sur offshore waters. Please refer to the Tropical Waves and Monsoon Trough/ITCZ sections above for information about additional convection in the region. Away from the impacts of Genevieve, moderate to locally fresh NW winds associated with high pressure building in from the northwest are impacting waters N and W of Guadalupe Island. This same high is leading to moderate to locally fresh winds just offshore Cabo San Lucas and in portions of the far southern Gulf of California. Elsewhere, moderate or weaker winds prevail. Seas are slight in the Gulf of California and moderate in the remaining offshore waters, except rough to very rough west of 110W and offshore Baja California due to Genevieve. For the forecast, Hurricane Genevieve will move to 19.2N 120.7W this evening, 19.9N 123.1W Thu morning, 20.6N 125.5W Thu evening, weaken to a tropical storm near 21.4N 128.0W Fri morning, 22.1N 130.7W Fri evening, and 23.0N 133.5W Sat morning. Genevieve will become post-tropical as it moves to 24.7N 139.1W early Sun. Associated seas of rough or greater will finally subside across the offshore waters of Baja California through the day Thu. Elsewhere, fresh to locally strong northerly winds are likely in the Gulf of Tehunatepec Thu and Fri nights. Otherwise, areas of fresh mainly westerly gap winds are expected through tonight nearshore Baja California as high pressure builds southward to the west of the Baja California Peninsula. Looking ahead, rough northerly seas may 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 Monsoon Trough/ITCZ and Tropical Wave sections above for information about convection in the region. High pressure northeast of the area is forcing fresh to locally strong easterly gap winds and seas of 5 to 7 ft across the Gulf of Papagayo region, with moderate 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 the weekend, with occasionally rough seas. Pulsing moderate to locally fresh N winds are expected in the Gulf of Panama tonight. 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 Major 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 around the periphery of the ridge including from 20N to 30N and west of 120W, and from 10N to 20N and west of 130W. Moderate to locally fresh SE winds are found south of 06N and west of 110W. Moderate or weaker winds are elsewhere. Moderate seas dominate the waters away from Genevieve. For the forecast, Hurricane Genevieve will move to 19.2N 120.7W this evening, 19.9N 123.1W Thu morning, 20.6N 125.5W Thu evening, weaken to a tropical storm near 21.4N 128.0W Fri morning, 22.1N 130.7W Fri evening, and 23.0N 133.5W Sat morning. Genevieve will become post-tropical as it moves to 24.7N 139.1W early Sun. Away from Genevieve, little change in marine conditions is forecast across the remainder of the waters into next weekend. Looking ahead, 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 this weekend into early next week.
