Baja California / Gulf of California: A deep layer trough is moving across the Baja California peninsula and Gulf of California this afternoon. Recent scatterometer data shows a well defined trough passing south of Guadalupe Island off Baja California Norte, supporting areas of 20 to 25 kt winds. Northwest swell to 9 ft is also propagating into this region. A cold front ahead the front is moving across the central Gulf currently, and will dissipate through early Monday. Strong northwest winds will follow the trough tonight and Monday morning across the Gulf of California and off Baja California Sur. Winds and seas diminish across the region through late Monday, leaving gentle to moderate breezes in place through mid week. Farther south, strong gap winds will briefly pulse into the Gulf of Tehuantepec late tonight. Light to gentle breezes will follow through mid week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Strong gap winds will pulse through the Gulf of Papagayo tonight and Monday night, but not as strong or long lasting as the past couple of days. Moderate to fresh gap winds will follow during overnight hours through mid week through the Gulf of Papagayo and the Gulf of Panama. Light to gentle winds and combined seas of 3-6 ft are occurring elsewhere outside the gap wind events with little change expected through mid week. REMAINDER OF THE AREA... Strong southerly winds and 8 ft seas over the northwest waters of the discussion area north of 28N and west of 135W will persist through Monday ahead of a pair of cold front currently west of the area. Southwest winds will increase and expand eastward into mid week accompanied by northwest swell to 18 ft pushing southwest of 30N140W by late Tuesday. Looking ahead, the cold front will enter the northwest area by Wednesday, but supporting upper dynamics will lift northeast of the area allowing the winds to diminish into Thursday.
