Full Alert Message

Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Thu Apr 2 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 0600 UTC surface analysis and satellite imagery through 0700 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07.5N78W to 05.5N94W. The ITCZ extends from 05.5N94W to 03N120W to beyond 04.5N140W. A second ITCZ extends from S of 03.4S to 03.4S110W to 02.5N116W to beyond 03S120W. Scattered moderate convection is noted from 03N to 08N between 80W and 97W, and from 03N to 09N between 128W and 134W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure is building SE toward northern waters, causing some locally fresh NW winds offshore Cabo San Lucas and Cabo Corrientes per recent ASCAT scatterometer data. Otherwise mainly gentle to moderate winds prevail. Moderate seas prevail, except for slight seas in the Gulf of California. For the forecast, fresh winds will continue pulsing near Cabo Corrientes and Cabo San Lucas through early this morning before diminishing. Fresh to locally strong NW winds will dominate offshore Baja California this evening into Fri as high pressure builds W of the peninsula. Similar winds are likely to redevelop there early next week. Fresh NW-N winds will pulse in the northern Gulf of California Fri afternoon. NW swell will bring locally rough seas off Baja California Norte Fri through Sat night. Looking ahead, strong to near gale-force N gap winds will develop in the Gulf of Tehuantepec Sun night into Mon night, building seas to rough. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh NE-E gap winds prevail over the Papagayo region. Winds are light to gentle elsewhere. Slight seas are offshore Colombia, with moderate seas elsewhere N of the Equator, and rough seas in S-SW swell S of the Equator from Ecuador to the Galapagos Islands. For the forecast, fresh winds will pulse nightly in the Papagayo region through the period. Large S-SW swell spreading into the waters from offshore Ecuador to the Galapagos Islands will reach all area waters later today. This swell will support seas to rough from offshore Ecuador to the Galapagos Islands through early Fri. Seas will then very gradually subside across the waters through the weekend. ...REMAINDER OF THE AREA... Low pressure is just W of the NW waters near 23.5N145W at 1014 mb. Broad high pressure prevails over the waters N of the ITCZ with gentle to moderate trades across the open waters, mainly light to gentle S of the ITCZ and E of 115W. Moderate seas prevail through the basin, except rough seas S of 03N and E of 120W in S-SW swell. For the forecast, gentle to moderate winds will dominate the open waters through this morning as weak high pressure across much of the area slowly builds into the Baja California waters. Broad low pressure and troughing will extend from W of 140W eastward into the NW waters later today, resulting in developing fresh to locally strong NE-E winds N of 25.5N and W of 133W and locally rough seas. These conditions will then drift N through Fri before departing. Large southerly swell will reach 10N later today, then gradually subside. The pressure gradient will likely tighten N of the ITCZ to 20N and W of 110W by the end of the week through the weekend, increasing trades to moderate to locally fresh, with seas building locally to rough as a result. Northerly swell will likely build seas to rough just S of 30N in the N-central waters by early Fri into the weekend.
