Strong N gap winds are ongoing in the Gulf of Tehuantepec due to the tight pressure gradient between high pressure over the NW Gulf of Mexico and lower pressure associated with newly formed Tropical Depression Five-E, described in the Special Features section above. These winds should diminish tonight as the disturbance moves farther west of the area. Light to gentle breezes are noted elsewhere with moderate seas in open waters and slight seas over the Gulf of California. For the forecast, aside from the impacts of Tropical Depression Five-E, depicted in the Special Features section above, winds and seas offshore Baja California Norte may increase beginning late Wed, in association with a weak surface trough. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE to E gap winds are noted across the Gulf of Papagayo, with 4 to 6 ft seas. Moderate S winds are within 750nm of Ecuador including the Galapagos Islands, with 4-6 ft seas in S swell. Gentle breezes persist elsewhere, with 3 to 5 ft seas. For the forecast, fresh to strong E gap winds will pulse across the Papagayo region overnight, then diminish into Tue, with moderate to fresh W winds prevailing thereafter. Gentle to moderate winds and slight to moderate seas will persist elsewhere. ...REMAINDER OF THE AREA... See Special Features section above for details on newly-formed Tropical Depression Five-E. Swell from the southern hemisphere south of 10N between 110W and 140W persists around 5-7 ft. Elsewhere, mainly gentle to moderate winds and 4-6 ft seas prevail across the area. For the forecast, Five-E will impact the waters between 10N and 20N as it develops and moves westward through the week. See hurricanes.gov for more information. Farther south, southerly swell will move into the waters south of 05N and west of 115W through Thu, with combined seas reaching 8 ft. Elsewhere, moderate winds and seas will persist across the region. $$ Christensen
