Please refer to the Special Features section for details on the Gulf of Tehuantepec Gale Warning. Aside from the Gale Warning in the Gulf of Tehuantepec, a weak ridge extends along the offshore waters of Baja California. This pattern supports moderate to locally fresh NW to N winds from Cabo San Lazaro northward offshore Baja California. Winds are mainly light to gentle across the remainder of the waters away from the Gulf of Tehuantepec, including in the Gulf of California. Seas are mainly 5 to 6 ft away from the Gulf of Tehuantepec in a mix of S and NW swells, with seas 3 ft or less in the Gulf of California. For the forecast, gale conditions in the Gulf of Tehuantepec will diminish by late this morning, then winds and seas will continue to decrease tonight into Wed. Moderate to locally fresh NW winds and moderate seas are expected off Baja California through Thu night. Winds may pulse to strong speeds N of Punta Eugenia at times through Thu evening. Moderate to fresh SW winds may develop in the northern Gulf of California Fri night ahead of a cold front approaching Baja California Norte, then to fresh to strong Sat night. Winds will be moderate or weaker elsewhere through the next several days. Little change in seas is forecast through the week. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to locally strong gap winds are blowing across the Gulf of Papagayo and downwind to 89W. Seas are 5 to 6 ft with these winds. Farther east, moderate N winds and 3 to 4 ft seas are present in the Gulf of Panama. Light to gentle winds and moderate seas dominate the remainder of the offshore forecast waters. For the forecast, fresh to locally strong gap winds are expected during the nighttime and early morning hours in the Papagayo region and downwind to about 89W through the forecast period. Moderate to locally fresh northerly winds are forecast in the Gulf of Panama through the forecast period. The ongoing gap wind event in the Tehuantepec region will produce seas to 9 ft in the far offshore waters of Guatemala through today. Light to gentle winds and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... A weak cold front extends from 30N134W to 25N140W. Seas to 8 ft follow the front. E of front, a 1020 mb high pressure located near 35N125W extends a ridge across the remainder of the N waters, particularly N of 20N and W of 110W. Gentle to moderate winds and moderate seas are noted under the influence of the ridge. The pressure gradient between the ridge an lower pressures in the vicinity of the ITCZ supports moderate to locally fresh winds in the trade wind zone, mainly W of 125W with seas of 5 to 7 ft. Elsewhere, moderate or weaker winds and moderate seas are prevalent. For the forecast, the cold front will continue to move SE as it weakens, and seas behind the front will subside later today. Continuing high pressure will support moderate to locally fresh easterly winds and moderate to locally rough seas across the trade wind zone through the forecast period, supporting seas to around 7 ft.
