OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please read the Special Features section for details on Hurricane Linda. A weak surface ridge extends from 1024 mb high pressure well northwest of the area near 37N136W 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. Seas are around 5 to 7 ft in SW swell off Costa Rica and western Panama and 4 to 6 ft elsewhere. For the forecast, the gentle to moderate winds and moderate SW swell will persist into Tue. Expect increased SW swell across the region by mid week, gradually subsiding through Fri. REMAINDER OF THE AREA... Please read the Special Features section for details on Hurricane Linda. Hurricane Linda will impact the region from roughly 15N to 25N west of 120W through Thu as it continues to move westward. Gentle winds and moderate seas are evident north of this zone. Moderate SE winds and moderate SW swell are noted farther south. East of 110W, fresh SW monsoon flow is evident, with seas reaching 7 ft. For the forecast, moderate to locally fresh NW winds will follow a trough moving into the waters off Baja California by mid week. Long period NW swell will also follow this trough, reaching as far south as 27N after Wed. South of the monsoon trough and east of 110W, fresh to strong SW flow with reinforcing SW swell will allow seas to build to 9 ft through mid week. $$ Christensen
