OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please read the Special Features section for details on Hurricane Linda. Winds are diminishing near Clarion Island as Linda cotinues to move westward and away from the Revillagigedo Islands. Elsewhere mostly moderate NW winds are noted over the offshore waters of northern Mexico, pulsing to fresh off Punta Eugenia and Cabo Corrientes. Swell ranging from 7 to 9 ft from Linda is impacting the coast of Baja California as well. Moderate seas are noted elsewhere over open waters. Farther south, strong gap winds are noted in the Gulf of Tehuantepec. For the forecast, Linda will slowly diminish as it continue to move westward and away from the Mexican offshore waters through mid week. Swell generated from Linda will continue to impact the waters off Baja California into mid week. Farther south, fresh to strong gap winds in the Gulf of Tehuantepec will diminish through Sun. Looking ahead, expect increased SW swell in the waters off southern Mexico by mid week. Associated south to southwest swell from Linda will affect the Baja offshore waters through Mon before fading quickly. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office. Elsewhere, fresh gap winds across the Gulf of Tehuantepec will pulse to strong tonight. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate NE 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 the middle of next week, supporting scattered showers and thunderstorms across the region. New southerly swell will impact the waters offshore of Ecuador Sun night into early next week, reaching the near shore waters of Central America by Mon evening. REMAINDER OF THE AREA... Please read the Special Features section for details on Hurricane Linda. The 1017 mb remnant low of Kevin is centered near 30N128.5W. Earlier scatterometer satellite data indicated fresh NE winds occurring 90 to 210 nm north of the low, and mostly north of the discussion area. Seas to 7 ft are likely lingering in this area of fresh winds. 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 5 to 7 ft in mixed long period swell are noted outside of Linda and the remnant low of Kevin. Linda is forecast to remain a hurricane through the weekend as it continues generally westward. Strong E to SE swell generated from Linda will affect the waters north of 13N and west of 120W for the next few days. Elsewhere, southerly swell from the southern hemisphere will cross the Equator tonight through mid week, resulting in seas building to 7 to 9 ft south of 14N between 85W and 125W by Tue evening. $$ Christensen
