Full Alert Message

Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Tue Apr 14 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 1800 UTC surface analysis and satellite imagery through 2000 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N76W to 05N90W to 03N111W. The ITCZ extends from 03N111W to 05N125W to beyond 04N140W. Southern hemispheric ITCZ extends from 04S93W to 03S108W to beyond 02S120W. Numerous moderate to strong convection is noted from 01N to 11N between 120W and 140W. Scattered moderate isolated strong convection is noted from 00N to 07N between 84W and 105W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure building southward from offshore California is leading to fresh NW winds for waters N of Cabo Corrientes and the Revillagigedo islands, including much of the Gulf of California. Seas in these offshore waters are 5 to 7 ft, with 3 to 5 ft seas in the Gulf of California. Fresh N gap winds are in the Gulf of Tehuantepec, where seas are around 6 ft. Elsewhere, mainly gentle winds prevail, with moderate seas. For the forecast, fresh NW winds will impact the waters on both sides of the Baja California Peninsula into tonight as high pressure builds in from the North Pacific. This ridging will then dominate the waters through the week. NW swell will propagate into Baja waters Thu and may bring rough seas into Sat. Between Baja Sur and Puerto Angel, winds will be moderate or weaker with moderate seas through Fri. Pulsing fresh to strong northerly gap winds will prevail across the Tehuantepec region into this afternoon. Looking ahead, high pressure will weaken across the region Sat leading to diminishing winds and seas. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE to E gap winds prevail across the Papagayo region and extend downwind to near 89W, producing seas 7 to 8 ft. Moderate to fresh N to NE winds and moderate seas prevail in the Gulf of Panama and extend beyond the Azuero Peninsula to near 05N. Light to gentle winds and moderate seas in SW swell dominate the remainder of the offshore forecast waters. Scattered moderate isolated strong convection continues across the offshore waters of Costa Rica and extends southward to near the equator north of the Galapagos Islands. For the forecast, broad high pressure will continue N of the area into Wed night before gradually weakening through the end of the week. This will maintain fresh gap winds pulsing to strong during the nighttime and early morning hours across the Papagayo region to near 90W through Wed night, then yield moderate winds pulsing to fresh each night into the weekend. In the Gulf of Panama, moderate northerly winds will pulse to fresh tonight and Wed night, then will diminish slightly through the rest of the week. Light to gentle winds and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... High pressure N of the area extends a ridge southward into the area W of 110W. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ supports moderate to fresh winds south of 14N between 100W and 125W, and moderate to fresh NE to E winds south of 25N and west of 125W. Scattered convection has become more active along and N of the ITCZ W of 120W, and is producing areas of strong and gusty winds. 1030 mb high pressure will shift southeastward to near 33N through Wed, and strengthen the pressure gradient modestly across the local area. Cross- equatorial swell will raise seas along the equator 7 to near 8 ft through Wed. Moderate to fresh winds are expected in the trade wind zone through Fri.
