Similar convection is in a band between 480 nm and 1200 nm in the SW quadrant. Elida is moving toward the northwest and this motion is expected to continue through Sat. A north- northwestward motion is forecast later this weekend and into early next week. Little change in strength is expected overnight. Weakening is forecast to begin later on Sat and continue through early next week. Swells generated by Elida will affect portions of the west coast of the Baja California peninsula through this weekend. These swells 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 Elida NHC Forecast/Advisory and Public Advisory at www.hurricanes.gov for more details. Central and Western East Pacific (EP97): A tropical wave with axis along 105W, or several hundred nautical miles south- southwest of the coast of southwestern Mexico continues to produce a large area of disorganized showers and thunderstorms. Nearby convection is described with the monsoon trough/ITCZ below. Environmental conditions appear conducive for development of this system, and a tropical depression is expected to form over the weekend while it moves west-northwestward to northwestward at 10 to 15 kt over the central portion of the eastern Pacific. The latest Tropical Weather Outlook gives this system a high chance of tropical cyclone formation through 48 hours. Regardless of tropical cyclone formation, expect increasing winds and building seas to impact portions of the waters well offshore southwest Mexico to the Revillagigedo Islands this weekend into early next week. Please read the latest TROPICAL WEATHER OUTLOOK issued by the National Hurricane Center at www.hurricanes.gov for more information. ...TROPICAL WAVES... A tropical wave is along 105W from 01N to 18N.

Very active convection is present near the monsoon trough across much of the offshore waters, with locally higher winds and seas possible near thunderstorms. For the forecast, fresh to strong northeast to east winds and moderate to rough seas will persist across the Papagayo region through early next week, with moderate to fresh northeast winds pulsing near the Gulf of Fonseca. Gentle to moderate N winds are expected in the Gulf of Panama with slight to moderate seas. Moderate or weaker winds and moderate seas in southwest swell are expected elsewhere, except in the immediate lee of the Galapagos Islands and nearshore western Colombia where slight seas are forecast ...REMAINDER OF THE AREA...Corrected Please refer to the Special Features section for details on Tropical Storm Elida, centered about 812 nautical miles west of the southern tip of Baja California, and on a broad area of low pressure, Invest EP97, near 11N107W, with the high potential for tropical cyclone formation. High pressure continues to dominate the majority of the forecast waters north of the monsoon trough and north and west of Elida. The pressure gradient between the ridge and Elida supports moderate to fresh north to northeast winds north of 15N and west of 120W, with moderate seas away from Elida. Winds are mainly moderate or weaker elsewhere, except near the SPECIAL FEATURES low pressure area, Invest EP97, near 11N107W, with 5 to 7 ft seas in mixed swell across the open waters away from Elida. For the forecast, Tropical Storm Elida will move to near 21.0N 124.6W late tonight, to near 23.0N 125.7W Sun afternoon, to near late Sun night, to near 27.6N 127.0W Mon afternoon, then become post- tropical and move to 30.1N 127.3W Tue morning, and weaken to a remnant low north of the area near 32.9N 127.6W by Tue afternoon. Seas generated by Elida will continue to propagate across the forecast region, covering roughly the waters from 10N to 26N between 113W and 133W this afternoon. Seas are mostly rough over some of the far south-central waters as southwesterly flow into Invest EP97 is appearing to become establised. These seas will gradually spread northward over the south-central waters as that occurs. Little change in marine conditions is expected across the remainder of the open waters going into the early part of the week. $$ Aguirre ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC182229CCA_C_KWBC_20260718222940_32440682-5635-TWDEP.txt ****0000009735**** AXPZ20 KNHC 182229 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 2205 UTC Sat Jul 18 2026 Corrected Remainder of the Area section 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 1800 UTC surface analysis and satellite imagery through 2145 UTC. ...SPECIAL FEATURES... Tropical Storm Elida: Tropical Storm Elida is centered near 19.7N 124.0W at 18/2100 UTC, moving north-northwest at 10 kt. Estimated minimum central pressure is 990 mb. Maximum sustained wind speed is 60 kt with gusts to 75 kt. Peak seas remain around 24 ft, or about 7 m. Elidas's satellite presentation has improved slightly since this morning. The satellite imagery depicts numerous moderate to isolated strong convection in a wide band from 17N to 19N between 122W and 124W and from 17N to 21N between 124W and 127W. Scattered moderate to isolated strong convection is noted east- southeast of Elida from 10N to 20N between 117W and 126W, and also well to its south from 05N to 11N between 126W and 133W. Elida is forecast to increase its forward speed through much of the weekend. An eventual turn to the north is forecast to occur by late Sun. The system is expected to begin weakening later tonight with that weakening trend forecast to continue over the next few days as the storm moves over cooler waters. Elida is likely to become a post- tropical cyclone on Mon. Swells generated by Elida will affect portions of the west coast of the Baja California peninsula through the rest of the weekend. These swells 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 Elida NHC Forecast/Advisory and Public Advisory at www.hurricanes.gov for more details. Storm Warning Central and Western East Pacific (Invest EP97): A broad 1008 mb area of low pressure located several hundred nautical miles south-southwest of the coast of southwestern Mexico near 11N107W. Scattered moderate to isolated strong convection is becoming better organized from 10N to 17N between 105W and 111W and also from 08N to 10N between 107W and 113W. Associated winds as depicted in a recent Ascat pass are currently 20 to 30 kt as depicted by a recent satellite scatterometer data pass. Seas with these winds are in the 7 to 9 ft range. Environmental conditions appear conducive for continued development of this system, and a tropical depression is expected to form tonight or on Sunday while it moves west- northwestward over the central portion of the eastern Pacific. The latest Tropical Weather Outlook gives this system a high chance of tropical cyclone formation through the next 48 hours. Regardless of tropical cyclone formation, expect increasing winds and building seas to impact portions of the waters well offshore southwest Mexico to the Revillagigedo Islands during the rest of the weekend and into early next week, and a Storm Warning is now in effect beginning late Sun night into early Mon, with gale conditions possibly beginning sooner. Please read the latest TROPICAL WEATHER OUTLOOK issued by the National Hurricane Center at www.hurricanes.gov for more information. ...TROPICAL WAVES...
