OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Strong high pressure over the western Atlantic extending to the northern Caribbean continues to support a tight pressure gradient enhancing fresh to strong NE to E gap winds across the Papagayo region with seas to 8 ft. Light to gentle variable winds with seas to 6 ft are elsewhere, except for moderate SW winds off the coast of Colombia and Ecuador. For the forecast, fresh to strong NE to E gap winds will pulse across the Papagayo region through early next week with seas building to 8 ft today.

Large NW to N swell from the Gulf of Tehuantepec will impact the Guatemala and El Salvador offshore waters tonight through Sun night. Strong cold front is forecast to move across the Gulf of Mexico and increase the chances for gale force winds to develop over the Gulf of Tehuantepec by the end of the week. REMAINDER OF THE AREA A frontal boundary is apporaching from the NW, enhancing the seas N of 20N and W of 133W. A surface trough, reflection of an upper-level low, extends from 15N113W to 11N124W. Scattered showers and thunderstorms are noted in the vicinity of this trough, mainly N of 11N between 110W-130W. For the forecast, the frontal boundary will stall W of the area. Large swell will continue moving E across the NW portion of the basin, with seas ranging between 8-11 ft during the next few days. The surface trough in the vicinity of 120W will prevail across the area over the next few days with convection. Gentle to moderate winds will prevail across the basin through the end of the week. $$ ERA
