Looking ahead, fresh to strong winds will develop W of the Baja California peninsula by early next week as a frontal boundary approaches from the W. Seas to 11 ft will develop in this area. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR The pressure gradient associated to high pressure over the western Atlantic is maintaining fresh to strong northeast to east winds in the Gulf of Papagayo region. Seas over these waters are 5-8 ft. Fresh north to northeast winds are in the Gulf of Panama, extending southward to 04N, along with seas of 4-6 ft.
