The front has ushered in a set of large NW swell, with seas of 10 to 14 ft over the waters off Baja California Norte. Seas 8 ft or greater will prevail west of the Baja California peninsula through Sat before diminishing. Another set of NW swell will move into the waters off Baja California Norte early Mon. In the Gulf of Tehuantepec, moderate to fresh northerly gap winds will pulse to around 20-25 kt each night through early Sat, then again Sun night, with gale force winds possible Mon night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to occasionally strong NE to E winds will pulse across and downstream from the Gulf of Papagayo at night through Monday.
