Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1005 UTC Mon Jul 06 2026 Corrected forecast under Offshore Waters Within 250 nm of Mexico 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 0945 UTC. ...TROPICAL WAVES... A tropical wave is analyzed along a position from 16N114W to 05N116W. It is moving westward at 15 to 20 kt. Scattered moderate convection is west of the wave to 120W from 08N to 12N, and within 60 nm east of the wave from 08N to 12N. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from northwest Colombia southwestward through southern Costa Rica, then northwestward to 09N87W, where it transitions to the ITCZ to 10N95W to 07N104W to 09N114W, then resumes at 08N122W to 07N132W and to beyond 08N140W. Numerous moderate to strong convection is from the Equator to 08N west of 132W. Numerous moderate to isolated strong convection is seen from 02N to 08N between 115W-130W. Scattered moderate convection is within 60 nm south of the ITCZ between 88W-90W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...Corrected A broad surface ridge extends from the northeast Pacific across the Baja California waters to near 19N115W. The pressure gradient between this ridge and relatively lower pressures over northwest Mexico is generally supporting moderate to fresh northwest winds offshore Baja California. Seas are 4 to 6 ft over these waters. Fresh north winds are along the Gulf of Tehuantepec coast and offshore for about 60 nm. Seas are 6 to 8 ft in long-period southwest swell. Elsewhere, gentle to moderate northwest to north winds are present per latest scatterometer satellite data along with seas of 4 to 6 ft in long-period south to southwest swell. Inside the Gulf, light to variable winds are over the northern Gulf of California, and southeast to south moderate winds over the rest of the Gulf. Seas are 3 to 4 ft over the Gulf. Numerous moderate to strong convection is seen from 13N to 16N between 91W and 95.5W, including the eastern portion of the Gulf of Tehuantepec. For the forecast, the surface ridge will build east-southeastward across the offshore waters of Baja California through Wed night, with the resultant gradient leading to moderate to fresh northwest winds over these same waters. Moderate to fresh gap winds in the Gulf of Tehuantepec will begin to pulse at fresh to strong speeds starting Tue morning, and pulse at night into the mornings afterward through Wed, then at fresh speeds through the rest of the week. Southern Hemispheric cross-equatorial swell moving through the waters off southern Mexico tonight is producing peak seas of 8 ft. These seas should continue through Wed. Expect fresh to strong southerly winds in the northern Gulf of California Thu through Fri. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong northeast winds are continuing across the Papagayo region and extend offshore to near 92W, where seas are 6 to 8 ft in long-period south to southwest swell. Mostly gentle to moderate south to southwest winds are noted elsewhere south of 10N along with seas seas of 4 to 6 ft in cross-equatorial long-period southwest swell. For the forecast, the fresh to strong northeast to east gap winds in the Gulf of Papagayo region will continue into early Thu. Large cross-equatorial southerly swell will move through the waters off Ecuador and the Galapagos Islands through early Wed, building seas to a peak of 9 ft. The combination of the southerly swell with shorter period seas associated with gap winds will allow combined seas to build to a peak of about 8 ft offshore of northern Central America Tue through Wed. ...REMAINDER OF THE AREA... A broad ridge continues across the northeast Pacific and north of the discussion area. It extends southeastward to near the Revillagigedo Islands. The pressure gradient between this ridge and the remnant trough of Douglas analyzed from near 27N128W to 21N132W is producing fresh northeast winds within 180 nm west of the trough from 25N to 28N, and within 120 nm east of the trough from 25N to 28N. Seas are to 8 ft in a mix of northeast and southeast swell over these waters. The gradient associated to the ridge generally supports gentle to moderate trades from 09N to 16N west of about 118W, and from 09N to 13N between 110W and 118W. Seas are 5 to 7 ft over these waters in mixed swell. Farther east, moderate to fresh northeast to east winds downstream from the Papagayo region are from 08N to 12N between 91W and 105W. Seas are 5 to 6 ft with these winds as noted in the latest altimeter satellite data over this part of the area. Light to gentle easterly winds are elsewhere east of 110W. Seas of 4 to 6 ft primarily in long-period southwest swell are over this part of the area. Convection is noted with the aforementioned tropical wave that extends from near 16N114W to 05N116W. For the forecast, the remnant trough of Douglas will continue drifting westward through the rest of the week. The ridge will build east-southeastward through Wed night, with the gradient between it and the remnant Douglas trough leading to a solid area of fresh trades over the western half of the area along with seas of 7 to 8 ft. The tropical wave will continue moving westward with scattered moderate convection.
