979 AXPZ20 KNHC 132057 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Mon Apr 13 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 2030 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N78W to 05N102W. The ITCZ extends from 05N102W to beyond 04N140W. A southern hemispheric ITCZ extends from 04S98W to 02S118W. Scattered moderate convection is noted from 01N to 09N and E of 122W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A cold front is analyzed from 30N115W to 28N118W, then continues as a weak boundary to 24N139W. Weak high pressure is collapsing ahead of the front and yielding light to gentle NW to N winds across the nearshore waters of Baja and Mexico, and light NE winds farther offshore becoming gentle NE winds across the Revillagigedo Islands. Moderate seas in mixed swell prevail across these waters. Behind the front, gentle to moderate NW winds prevail, with seas 5 to 7 ft in fresh NW swell. Gentle N winds prevail across southern portions of the Gulf of California seas of 3 to 4 ft, while fresh SW gap winds and moderate seas prevail continue across north portions of the Gulf. Fresh to strong N gap winds are noted in the Tehuantepec region N of 15N, where seas are around 6 ft. For the forecast, the cold front will gradually dissipate across central Baja and the central Gulf of California on Tue. Expect fresh NW to N winds across the Baja waters through Tue. High pressure behind the front will build across the region and dominate conditions through the rest of the week. Fresh to strong SW to W gap winds are expected in the northern Gulf of California tonight ahead of the front, with winds then becoming moderate to fresh from the N through the entire Gulf early Tue morning through Wed evening. Elsewhere between Baja Sur and Puerto Angel, winds will be moderate or weaker with moderate seas through Tue. Pulsing fresh to strong northerly gap winds will prevail across and downwind of the Tehuantepec region through Tue afternoon. Afterwards, moderate and variable winds are expected there through Fri. ....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 90W, producing seas to 8 ft. Moderate to fresh N winds and moderate seas in SW swell 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 convection continues across the near and offshore waters of western Panama and Costa Rica, while strong convection occurring over NW Colombia is reaching the Pacific coast and waters within 20 nm. For the forecast, broad high pressure will continue N of the area through Wed before weakening, and will maintain fresh gap winds pulsing to strong during the nighttime and early morning hours across the Papagayo region to near 90W. In the Gulf of Panama, moderate northerly winds, pulsing to fresh each night, are expected throughout the forecast period. Light to gentle winds and moderate seas will prevail elsewhere. Cross-equatorial SW swell will raise seas to 6 to 8 ft between Ecuador and the Galapagos Islands Tue through Wed evening. ...REMAINDER OF THE AREA... High pressure NW of the area extends a ridge southward into the area W of 125W. East of the ridge, a cold front is analyzed from 30N115W to near 17N120W, then weakens to 24N139W. Moderate to fresh N to NE winds prevail north of the front, with building seas 5 to 7 ft in NW swell. The pressure gradient between the ridge and lower pressures in the vicinity of the ITCZ supports moderate to fresh winds south of 15N to west of 100W. Moderate seas in mixed NW and S swell generally prevail across the area waters south of the front, with seas to 7 ft within the trade wind zone between 90W and 120W. For the forecast, the weak high pressure ridge will dominate the weather pattern across the northern forecast waters through today with little change in winds and seas, before high pressure behind the front shifts southeastward to near 33N through midweek, and strengthens the pressure gradient across the local area. The weakening cold front across the northern waters will move into the central Baja Peninsula by Tue then gradually dissipate. Moderate N to NE winds and moderate to briefly rough seas in NW swell are forecast in the wake of the front through Wed. Moderate to fresh winds are expected in the trade wind zone through Fri. $$ ERA
