This will support a strengthening of northerly gap winds over the Gulf of Tehuantepec tonight through Monday. Elsewhere, gentle to moderate NW winds prevail across the waters north of 20N with 5 to 6 ft seas west of the Baja California peninsula. Little change in marine conditions is expected during the next few days. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate to fresh SW winds prevail S of the monsoon trough. Seas are 6 to 8 ft in long-period southerly swell. Moderate to fresh SW winds and southerly cross-equatorial swell will persist south of the monsoon trough the next several days. REMAINDER OF THE AREA... Gentle to moderate winds prevail north of the monsoon trough. Moderate to fresh southerly flow persists south of the monsoon trough, with areas of 7 to 8 ft seas. Long-period southerly swell is spreading northward across the region E of 120W, with seas in the 7 to 9 ft range. This swell will gradually subside through early next week. $$ AL
