Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 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 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from 09N79W to 08N105W. The ITCZ extends from 08N105W to 10N125W to beyond 07N140W. A second ITCZ is south of the discussion waters. Numerous moderate to isolated strong convection is active from 10N to 12N between 105W and 120W. Scattered moderate convection is active from 10N to 12N between 125W and 132W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Strong to near-gale force SW to W gap winds persist across the northern Gulf of California currently, following a cold front moving through the area. Seas are likely 5-7 ft over the northern Gulf of California. Weak ridging following the front is supporting moderate to locally fresh northwest winds over the offshore waters of Baja California, with gentle to moderate winds elsewhere. Combined seas are 4-6 ft off Baja California, 3-5 ft off southwest and southern Mexico, and 1-3 ft in the Gulf of California. For the forecast, the winds over the northern Gulf of California will diminish later this morning as weak ridging builds over the area. The pattern will support moderate to fresh northwest winds over the Baja California waters through mid-week, 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 early next week. Moderate to fresh winds may develop in the central and southern Gulf of California by the middle of next week as the pressure gradient tightens slightly. ....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 along with seas of 2-4 ft. Gentle to moderate southeast winds along with seas of 5-7 ft in long-period south to southwest swell continue south of the equator. For the forecast, a light gradient will maintain rather tranquil conditions over the Central American and Colombian waters through mid-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 starting Tue morning. ...REMAINDER OF THE AREA... The ridge north of 20N is disrupted by a trough extending from 30N125W to 22N140W. Moderate NE wind and 5-6 ft seas is evident west of the trough, with mostly gentle breezes and 4-6 ft combined seas east of the trough. Moderate NE trade winds and 5-7 ft seas are ongoing from 08N to 20N west of 120W, with gentle breezes and 4-6 ft elsewhere, except for 3-5 ft seas east of 95W. For the forecast, the rather weak high pressure across the region 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, locally to 8 ft near 140W through early evening, then 4-6 ft across the entire area early next week, except near 8 ft along 03.4S into early next week. Seas may build slightly over the waters north of 10N and west of 120W by the middle of next week in new swells.
