Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Fri Apr 10 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 surface trough extends from 05N78W to a 1009 mb low near 04N88W to 03.5N94W. The ITCZ continues from 05N100W to 06N120W to 06N140W. A second ITCZ is south of the Equator and runs from 05.5S87.5W to 03S105W to 00N123W. Scattered moderate to isolated strong convection can be found from 01N to 05N between 85W and 93W. Scattered moderate convection is noted from 04N to 10N between 120W and 132W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Strong to near-gale N winds are noted across the Gulf of Tehuantepec and downwind to 14.5N. Seas are 6 to 9 ft with these winds. A weak ridge continues to dominate the offshore waters of Baja California supporting gentle to moderate NW to N winds with moderate seas, except for locally fresh winds near Cabo San Lazaro. Light to gentle winds prevail across most of the Gulf of California. Elsewhere across the Mexican offshore waters, light to gentle winds and moderate seas, primarily in southerly swell, prevail. For the forecast, pulsing fresh to strong northerly winds are forecast in the Tehuantepec region through Sun morning, with seas around 8 ft. Afterwards, mainly moderate to fresh N winds are expected. Moderate to locally fresh NW winds and moderate seas are forecast off Baja California through Mon under the influence of a ridge. By Mon night into Tue, the pressure gradient may tighten enough between the ridge to the W and lower pressures inland Mexico to support moderate to fresh NW winds off the Baja California Peninsula. Fresh to locally strong SW to W winds are forecast in the northern Gulf of California Fri night through Sun night ahead of a couple of frontal boundaries approaching Baja California Norte. Northwest winds will also increase to moderate to fresh speeds beginning on Sun night over the central and southern parts of the Gulf of California. Seas will build to 3 to 6 ft within these winds. Elsewhere, winds will be moderate or weaker with moderate seas through the middle of next week. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong gap winds prevail across the Gulf of Papagayo and downwind to near 87W. Seas are 4 to 6 ft with these winds. Farther east, moderate to locally fresh N winds and seas of 3 to 5 ft are present in the Gulf of Panama, and downstream of the Azuero Peninsula. Light to gentle winds and moderate seas dominate the remainder of the offshore forecast waters. For the forecast, fresh to strong gap winds are expected mainly during the nighttime and early morning hours in the Papagayo area and downwind to near 90W through at least Tue night. Winds up to 30 kt, and seas up to 9 ft are forecast during the upcoming weekend. In the Gulf of Panama, moderate northerly winds, occasionally fresh, are forecast throughout the forecast period, with stronger conditions most likely during the upcoming weekend. Light to gentle winds and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... A ridge dominates the northern forecast waters N of 11N and W of 107W, including the Revillagigedo Islands, with a 1017 mb high pressure center located near 26.5N123W. Multilayer clouds, with possible showers, associated with strong upper level winds, are noted from 16N to 23N W of 118W. A surface trough is analyzed is this area and extends from 22N123W to 18N127W. The pressure gradient between the ridge and lower pressures in the vicinity of the ITCZ supports moderate to locally fresh winds from 07N to 15N and west of 120W. Elsewhere, moderate or weaker winds and moderate seas are occurring. For the forecast, high pressure will remain in control of the weather pattern across the forecast waters over the next several days with little change in winds and seas. Mainly moderate winds are expected in the trade wind zone. On Sun, another cold front will reach the N waters extending from 31N120W to 27N140W. Gentle to moderate N winds and moderate seas are expected in the wake of the front.
