Please read the Special Features section for details on Hurricane Linda. Overnight scatterometer satellite data showed tropical storm force winds on the periphery of Linda about 90 nm to the southeast of Socorro Island and beyond 210 nm off Cabo Corrientes. The same scatterometer pass indicated fresh to strong westerly gap winds into the northern Gulf of California overnight. Another scatterometer pass confirmed fresh to strong gap winds into the Gulf of Tehuantepec as well. Convergent low level flow related to this plume is supporting scattered thunderstorms downstream and just to the west of the Gulf of Tehuantepec as well. Light and variable winds prevail across the offshore waters of Baja California, where seas are 5-6 ft. SE swell from Linda has begun to reach the southern waters south of 23N and Baja California Sur, and will build to 7-9 ft today. The main impacts of Hurricane Linda will be in the Revillagigedo Islands and adjacent waters through early Sat. The center of Linda will move to 17.6N 113.6W this evening, then move toward Clarion Island tonight, before reaching 18.4N 115.9W Sat morning. Linda will continue to move west of the Revillagigedo Islands Sat afternoon. The remnant low of Kevin will continue to move WNW away from the offshore waters of Baja California, dissipating this weekend. Fresh to strong gap winds into the northern Gulf of California will diminish later this morning. Farther south, fresh to strong gap winds will continue to pulse through Sat night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate E winds are noted in the Papagayo region, with light to gentle winds elsewhere north of the monsoon trough. Moderate to locally fresh S-SW winds are south of the monsoon trough. Seas are in the 4 to 7 ft range in long period mixed swell. Mainly gentle winds will prevail north of the monsoon trough through early next week. South of the monsoon trough, mainly moderate, occasionally fresh, S to SW winds will prevail through early next week, supporting scattered showers and a few thunderstorms across the region. A set of southerly swell may impact the waters offshore of Ecuador early next week. REMAINDER OF THE AREA... Please read the Special Features section for details on Hurricane Linda. The 1008 mb remnant low of Kevin is centered near 26N124W. An overnight scatterometer satellite pass indicated winds have diminished since yesterday with mainly moderate to fresh winds within 180 nm of the center. Peak seas are estimated to be 8 to 9 ft. Elsewhere, weak surface ridging prevails across the remainder of the open waters. Gentle to moderate trades are noted north of the monsoon trough outside of the influence of Linda and remnants of Kevin, with moderate to fresh southerly flow south of the monsoon trough. Seas of 4 to 7 ft in mixed long period swell are noted outside of Linda and Kevin. For the forecast, the remnant low of Kevin will continue to move WNW away from the offshore waters of Baja California, dissipating this weekend. Linda is forecast to remain a hurricane through the weekend. Elsewhere, southerly swell from the southern hemisphere will cross the Equator Sun night through Tue, resulting in seas of 7 to 8 ft south of 10N between 100W and 125W. $$ Stripling
