Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Wed Apr 29 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 axis extends from 09N83W to 08N89W to 06N96W. The ITCZ extends from 06N96W to 08N124W to 05N140W. Numerous moderate convection is noted from 08N to 14N between 114W and 134W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Ridging off Baja California combined with troughing over northwest Mexico supports moderate to fresh NW to N winds and seas of 4 to 7 ft off the peninsula. Moderate NW winds with 3 to 4 ft seas are seen across the central and southern Gulf of California, and light to gentle winds and seas at 1 to 2 ft dominate the rest of the Gulf. Gentle winds with 4 to 6 ft seas in mixed moderate swell prevail for the offshore waters of central and southern Mexico. For the forecast, the pressure gradient between high pressure building southward from the North Pacific and lower pressure over NW Mexico will maintain fresh NW winds over waters on both sides of Baja California through Thu night, with winds locally pulsing to strong Thu into Thu night. By Sun into Mon, strong to near- gale force gap winds and rough seas will impact the Gulf of Tehuantepec. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE to E gap winds and seas of 4 to 6 ft are present at the Papagayo region. Moderate to fresh N winds with 3 to 4 ft seas are noted at the Gulf of Panama. Gentle S winds and 4 to 7 ft seas in moderate S swell persist in waters near the Galapagos Islands and off Ecuador. Light to gentle winds with 2 to 4 ft seas prevail for the remainder offshore waters in Central America and off Colombia. For the forecast, fresh NE to E winds will pulse in the Papagayo region tonight and Thu night. Moderate to fresh N winds will also pulse in the Gulf of Panama during this time. Moderate long- period S swell will will gradually diminish offshore Ecuador into the weekend. ...REMAINDER OF THE AREA... The pressure gradient between a surface trough extending from roughly 29N125W to 15N132W and high pressure to the NW is leading to fresh NE winds and 5 to 8 ft seas over the NW waters. Convection previously associated with this trough has dissipated this afternoon. Elsewhere N of the ITCZ, moderate to fresh mainly NE winds prevail, with 4 to 7 ft seas. To the S, similar seas prevail, in a mix of S and NW long period-swell, and mainly gentle SE winds dominate. For the forecast, winds south of the ITCZ will become light to gentle starting Thu night. Moderate to fresh NE winds and mainly moderate seas will prevail north of the ITCZ.
