Full Alert Message

Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed Apr 8 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 0800 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 09N85W to 05N96.5W. The ITCZ continues from 05N96.5W to 04N120W to 04N140W. A second ITCZ is south of the Equator and runs from 03S104W to 02.5S140W. Scattered moderate convection is noted from 05.5N to 10N, east of 105W and between 113W and 127W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to strong N to NE winds prevail across the Gulf of Tehuantepec along with seas 6 to 8 ft. Otherwise, a weak ridge dominates the offshore waters of Baja California. This pattern supports moderate to fresh NW to N winds with moderate seas. Gentle to locally moderate NW winds and slight seas are noted in 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 expected in the Tehuantepec region the remainder of the week with seas building up to 7 or 8 ft. Moderate to locally fresh NW winds and moderate seas are forecast off Baja California through Fri night under the influence of a ridge. Fresh to strong SW winds may briefly develop in the northern Gulf of California Fri night ahead of a cold front approaching Baja California Norte, then moderate to fresh SW winds are expected through the upcoming weekend. Elsewhere, winds will be moderate or weaker with moderate seas through the next several days. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh gap winds are blowing across the Gulf of Papagayo and downwind to 88W. Seas are around 4 ft with these winds. Farther east, moderate N winds and 3 to 4 ft seas are present in the Gulf of Panama and just south of the Azuero Peninsula. Light to gentle winds and moderate seas dominate the remainder of the offshore forecast waters. For the forecast, fresh to locally strong gap winds are expected during the nighttime and early morning hours in the Papagayo region and downwind to about 89W through Thu. Toward the upcoming weekend, winds may increase to 30 kt with seas building to 8 or 9 ft in the Papagayo area as a stronger high pressure settles N of the area. Moderate northerly winds are forecast in the Gulf of Panama through the forecast period. Light to gentle winds and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... A decaying stationary front is over the NW corner of the forecast region and extends from 30N134W to 25N140W. Seas are around 7 ft in the wake of the front. E of front, a 1023 mb high pressure located near 32N126W extends a ridge across the remainder of the N waters, particularly N of 19N and W of 110W. The pressure gradient between the ridge and lower pressures in the vicinity of the ITCZ supports moderate to locally fresh winds in the trade wind zone, W of 110W. Seas of 6 to 7 ft are within these winds. Elsewhere, moderate or weaker winds and moderate seas are prevalent. For the forecast, a surface trough will move into our waters and merge with the stationary decaying front by Wed night. Then the front will continue to move eastward across the waters N of 20N while dissipating by Fri. Gentle to locally moderate winds will follow the front along with seas 6 to 7 ft. A high pressure center located ahead of the front will move SE between 120W and 130W and weaken some over the next 48-72 hours. Moderate to locally fresh trades are expected along the southern periphery of the ridge through at least Thu.
