Full Alert Message

Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 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 1200 UTC surface analysis and satellite imagery through 1430 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07.5N78W to 06N94W. The ITCZ extends from 06N94W to beyond 01N140W. Scattered moderate convection is noted from 03N to 08N between 81W and 92W, and from 03N to 08N between 128W and 134W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between high pressure west of the area and a trough over the Gulf of California is supporting moderate to fresh winds west of Baja California, extending southward to Cabo Corrientes and the Revillagigedo Islands. Gentle to moderate winds are over the Gulf of California. Light to gentle winds are elsewhere over the open waters off Mexico. Moderate seas prevail across the open waters off Mexico, with slight seas over the Gulf of California. For the forecast, fresh to locally strong NW winds will dominate offshore Baja California this evening into Fri. 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. 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 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. Rough seas in S-SW swell prevail 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... Broad high pressure prevails over the waters N of 20N. The pressure gradient between the area of high pressure and lower pressure in the vicinity of the ITCZ wis supporting gentle to moderate winds N of the ITCZ. Light to gentle winds prevail south of the ITCZ. Rough seas in cross equatorial swell prevail S of 04N between 90W and 110W, with moderate seas elsewhere. For the forecast, broad low pressure and troughing will extend from W of 140W eastward into the NW waters later today. This will tighten the pressure gradient between this area and the ridge of high pressure to its east. The pressure gradient will support 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 shifting N of the area. 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.
