A cold front is progressing southward through central portions of the Gulf of Mexico, extending from 31N109W to 30N113W to 31N116W. Recent scatterometer satellite data show strong winds occurring north of 30N and fresh winds occurring north of 27N. Seas of 6 to 8 ft are occurring in association with these winds. Residual N to NW swell is leading to seas of 7 to 9 ft north of 28N and west of 119N offshore of Baja California Norte. Locally rough seas to 8 ft are also noted farther south, well offshore of Jalisco. Moderate to fresh SE to NE winds and locally rough seas are occurring well offshore of Guerrero and Michoacan due to the influence of Tropical Depression Fourteen-E. Otherwise, light to gentle NW winds and slight to moderate seas prevail across the remainder of the Mexico offshore waters. For the forecast, fresh to strong NW winds will continue across northern and central portions of the Gulf of California today, reaching southern portions of the Gulf this afternoon into Fri. These winds will occur through Fri before slowly diminishing on Sat. Moderate to rough seas will occur in association with the winds. Rough seas offshore of Baja California will subside today. Elsewhere, moderate to locally fresh NW winds will develop off the coast of southwestern Mexico tonight through Fri, offshore of Jalisco through Michoacan. Looking ahead, N winds will pulse in the Gulf of Tehuantepec this weekend into early next week. TD Fourteen E is expected to stay south and west of the southern Mexico offshore waters. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gentle to locally moderate S to W winds are occurring across the Central and South American offshore waters. A long-period S to SW swell is leading to seas of 6 to 8 ft offshore of Ecuador toward the Galapagos Islands, with the highest seas occurring south of 02N. Farther north, seas of 4 to 6 ft within S to SW swell are noted. For the forecast, moderate S to SW winds will develop offshore of Costa Rica through the forecast waters offshore of Ecuador today, with moderate winds expanding into the offshore waters from Nicaragua through Guatemala by Fri. Fresh SW winds are expected from 01N to 09N east of 89W Fri through Sat. Moderate to rough seas will occur with these winds. Elsewhere, southerly swell will bring seas 7 to 8 ft across the Ecuador and the Galapagos Islands offshore waters through Fri before subsiding by Sat. Light to gentle winds and seas of 4 to 6 ft will occur north of the monsoon trough through this weekend. ...REMAINDER OF THE AREA... Refer to the Special Features section for information regarding Tropical Depression Fourteen-E. A trough has been analyzed from 27N118W to 30N120W, and ridging dominates the remainder of the waters north of the monsoon trough. Fresh N to NE winds are occurring north of 28N and east of 130W, where seas of 8 to 10 ft are analyzed. Elsewhere north of the monsoon trough, moderate NE winds and seas of 7 to 8 ft are occurring. South of the monsoon trough, fresh to locally strong SW winds and seas of 8 to 11 ft are occurring surrounding a 1012 mb low centered near 13N118W. Otherwise, moderate to locally fresh SE to SW winds and moderate seas prevail south of the monsoon trough. For the forecast, Tropical Depression Fourteen-E will move to 12.5N 104.0W this afternoon, and dissipate Fri morning. Meanwhile, fresh N winds and rough seas north of 28N and east of 130W will slowly subside today. Winds will become moderate to locally fresh this weekend into next week N of the monsoon trough and W of 120W. Fresh to locally strong SW winds will occur just south of the monsoon trough this morning before diminishing, mainly north of 05N between 110W and 135W. Looking ahead, moderate to fresh S to SW winds and rough seas look to develop east of 110W, from the equator to 10N, Fri into this weekend. $$ ADAMS
