A weak surface ridge extends from 1026 mb high pressure well northwest of the area near 37N137W southeastward into central Baja California. Moderate to fresh NW winds are noted off Baja California Norte between the ridge and lower pressure over the southwest U.S. Recent scatterometer satellite data and ship observations showed mostly light to gentle NW winds off Baja California, with 5 to 7 ft seas in SW swell. Light breezes and slight seas persist throughout the Gulf of California. Farther south, light to gentle SW winds are noted south of Cabo Corrientes, with 3 to 5 ft in SW swell. Clusters of thunderstorms are ongoing from the Gulf of Tehuantepec through the coast of Guerrero. For the forecast, a trough will move into the waters off Baja California Norte tonight, and persist into mid week. This will allow a small area of westerly fresh to possibly strong gap winds over the far northern portion of the Gulf of California Tue night through Wed night. Expect increased SW swell in the waters off southern Mexico by mid week, gradually subsiding through Fri. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Recent scatterometer satellite data shows mostly gentle to moderate SW flow across the region. Convergence related to this wind flow is supporting scattered showers and thunderstorms off Colombia.
