Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 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 0600 UTC surface analysis and satellite imagery through 0830 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from 08N78W to 09N90W to 06N115W. The ITCZ extends from 06N115W to 07N125W to 04N140W. Numerous moderate to isolated strong convection is active from 10N to 13N between 113W and 122W. Scattered moderate convection is also active from 06N to 08N between 130W and 135W. ...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. 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 to fresh 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. ...REMAINDER OF THE AREA... The gradient related to broad high pressure north of 20N is generally supporting gentle to moderate trades from 05N to 15N west of 125W, where combined seas are 7 to 8 ft primarily in long-period north swell. Gentle to moderate north to northeast winds and moderate combined seas prevail elsewhere west of 105W. Gentle westerly winds and 3-4 ft seas are noted east of 105W. 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 Sat, then 4-6 ft across the entire area into early next week.
