Full Alert Message

Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sun Apr 26 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 1800 UTC surface analysis and satellite imagery through 1900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from the Gulf of Papagayo at 11N86W to 08N103W to 09N108W. The ITCZ extends from 09N108W to 10N128W to beyond 06N140W. A second ITCZ is south/southwest of the discussion waters. Scattered moderate and isolated strong convection is active from 01N to 05N between 81W and 96W, from 03N to 16N between 105W and 120W, and from 08N to 13N between 124W and 138W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The tail end of a dissipating cold front is analyzed across the central Gulf of California. Moderate to fresh winds are found in the central and northern Gulf of California, along with seas of 3-5 ft. Weak ridging following the front is supporting moderate to fresh northwest winds over the offshore waters of Baja California, with gentle to moderate winds elsewhere. Combined seas are 5-7 ft off Baja California, 3-5 ft off southwest and southern Mexico, and 1-3 ft in the southern Gulf of California. For the forecast, weak ridging will build over the area through early week. The pattern will support moderate to fresh northwest winds over the Baja California waters, except for moderate to fresh to occasionally strong winds funneling along the coast of Baja California Sur between between Cabo San Lazaro and Punta Eugenia tonight through Mon morning. Elsewhere, mostly light to gentle west to northwest winds are expected through the week. Moderate to fresh winds may develop in the central and southern Gulf of California by the middle of the week as the pressure gradient tightens slightly, then fresh to strong in the central Gulf of California Thu night as a cold front moves through the area. Seas may build to locally rough off Baja California Norte by the end of the week in NW swell. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle variable winds prevail north of the Equator. Gentle to moderate SE winds prevail south of the Equator. Seas are 3-4 ft N of 08N, and 5-7 ft in S to SW swell S of 08N. For the forecast, a light gradient will maintain rather tranquil conditions over the Central American and Colombian waters through the week while moderate to fresh southeast winds and moderate long-period south to southwest swell remain offshore Ecuador. Winds may pulse to moderate to fresh in the Gulf of Papagayo and the Gulf of Panama starting Tue morning through Thu morning. ...REMAINDER OF THE AREA... The ridge north of the ITCZ is disrupted by a trough extending from 28N125W to 20N130W. Moderate to locally fresh NE winds are found north of the ITCZ to 17N west of 118W. Gentle to moderate winds are west of the trough. Mainly light to gentle winds are elsewhere across the open waters. Seas are 6-8 ft in mixed SE and NW swell south of the Equator, and 4-7 ft across the remainder of the waters. For the forecast, the rather weak high pressure across the region along with persistent troughing over the northwest waters will generally maintain moderate to occasionally fresh trade winds from the ITCZ to 20N and west of 120W. Combined seas will be in the range of 5-7 ft over the western part of the area through the remainder of the weekend then 4-6 ft across the entire area early next week, except near 8 ft along 03.4S into the early part of the week. Seas may build slightly over the waters north of 10N and west of 120W by the middle of the week in new swells.
