See the Special Features section for details on an ongoing Gale Warning over the Tehuantepec region. A cold front is moving across the Baja California Norte peninsula and the Gulf of California. Moderate to fresh NW winds and seas of 8 to 11 ft associated with the front are affecting the Baja Norte offshore waters, except for fresh to strong winds and seas to 12 ft N of Punta Eugenia. Fresh to strong SW winds are also in the northern Gulf of California N of 29N with seas to 4 ft. Light to gentle variable winds are elsewhere across the Baja Sur offshore waters, remainder Gulf of California and SW Mexico offshore waters. Seas are 3 to 6 ft in NW swell over these regions, except to 3 ft in the Gulf of California. For the forecast, gale-force northerly gap winds in the Gulf of Tehuantepec will continue through Mon morning. The cold front across the Gulf of California will continue moving E while weakening today. Fresh to strong NW winds and seas to 16 ft associated with the front will continue to affect the Baja offshore waters through Mon. Fresh to strong S to SW winds in the northern Gulf of California will continue through Mon. By midweek, another low system N of the area will bring fresh to strong NW winds to the Baja offshore waters and seas to 17 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE winds continue offshore Nicaragua and the Gulf of Papagayo region, extending to near 88W. Seas are 8-10 ft in this area. Moderate to fresh N to NE winds are in the Gulf of Panama, extending southward to 04N with seas of 5-6 ft. Light to gentle variable winds prevail elsewhere, along with seas to 5 ft primarily in SW swell. For the forecast, fresh to strong NE to E winds across the Gulf of Papagayo region and Nicaragua waters will persist through the middle of the week. Winds are expected to reach near gale-force at night through midweek. Moderate to fresh N-NE winds in the Gulf of Panama will change little into next week, except pulse to strong at night starting tonight through mid-week. The storm- force gap wind event in the Gulf of Tehuantepec region will generate large NW swell that will propagate through the Guatemala and El Salvador offshore waters through tonight. REMAINDER OF THE AREA... Broad high pressure prevails over the area. An area of fresh to strong NE to E winds are across the waters from 07N to 30N and W of 125W. Large NE wind-generated seas are combining with NW swell moving through these waters resulting in seas of 8-12 ft. Elsewhere, moderate winds and seas are noted. For the forecast, high pressure will continue building east- southeastward supporting fresh to strong NE to E winds to the through Sun. Seas up to 12 ft will prevail over the western part of the area through today as the large NW swell propagates into that part of the area. A cold front moving across the Gulf of California will be followed by strong high pressure behind it tightening the gradient across the area. This will result in fresh to strong N to NE winds and large seas over much of the area waters W of 120W this weekend. Moderate winds and seas will prevail elsewhere through mid-week with the exception for an area of fresh to strong winds along the ITCZ mainly W of 130W on Tue/Wed. $$ Ramos
