Full Alert Message

Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Sat Apr 25 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 1300 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from 08N78W to 08N106W. The ITCZ extends from 08N106W to 09N117W to beyond 02N140W. A second ITCZ is south of the discussion waters. Scattered moderate to isolated strong convection is active from 03N to 06N between 81W and 86W, 02S to 02N between 85W and 92W, from 01N to 08N between 95W and 126W, from 09N to 15N between 104W and 121W, and from 04N to 11N between 127W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Broad ridging over the eastern Pacific west of Baja California is generally maintaining 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 southern Mexico, and 1-3 ft in the Gulf of California. For the forecast, the high pressure over the region will maintain moderate to fresh northwest winds over the Baja California waters well into next week. A tightening pressure gradient between high pressure northwest of the region shifting eastward, with a ridge extending southeastward across the Baja California offshore waters and low pressure over the western U.S. will induce strong to near gale southwest to west gap winds across the northern Gulf of California tonight into Sun. Winds will also increase slightly to fresh to strong between Cabo San Lazaro and Punta Eugenia Sun night through Mon morning. Elsewhere, mostly light to gentle west to northwest winds are expected through early next week. ....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 3-4 ft. 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 well into next 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 Gulf of Panama starting Tue morning. ...REMAINDER OF THE AREA... The gradient related to broad high pressure north of the ITCZ is generally supporting gentle to moderate trades across the open waters, except moderate to locally fresh near a trough analyzed from 27N130W to beyond 24N140W. Seas are mainly 5-7 ft in mixed swells across the open waters, except locally to 8 ft near 140W from 05N to 15N, and near 03.4S. For the forecast, the rather weak high pressure across the region will generally maintain moderate to 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 today, locally to 8 ft near 140W, then 4-6 ft across the entire area into early next week, except near 8 ft along 03.4S into early next week.
