Gentle winds and slight seas are over the Gulf of California. For the forecast, fresh to strong gap winds and rough seas are expected across the Gulf of Tehuantepec into the weekend. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. The pressure gradient between high pressure NW of the area and lower pressure over the Colorado River Valley will support fresh southerly winds across the northern Gulf of California late this weekend into early next week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...

High pressure prevails over the waters N of 20N. The pressure gradient between this area of high pressure and a tropical wave just west of 140W is supporting moderate to fresh winds from 15N to 20N and W of 135W. Seas over these waters are near 8 ft. Rough seas to 8 ft are found over the waters S of 05N between 100W and 120W. Elsewhere, gentle to moderate winds and moderate seas prevail. For the forecast, seas to 8 ft in the western tradewind waters will subside by Sat. Farther south, southerly swell to 8 ft will impact the waters south of 05N and west of 100W through the weekend.
