OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please read the Special Features section for details on Hurricane Linda. S to SW swell generated from Hurricane Linda continues to impact the waters off Baja California this morning, although seas have been subsiding and are likely 5 to 7 ft. Latest scatterometer satellite pass depicts moderate NW winds, while light breezes prevail across most of the Gulf of California. Farther south, fresh gap winds are likely ongoing into the Gulf of Tehuantepec, ahead of an approaching tropical wave. Seas are 4 to 6 ft off southern Mexico in SW swell, with seas slightly higher in the Gulf of Tehuantepec due to these gap winds. For the forecast, southerly swell generated from Hurricane Linda will continue to impact the waters off Baja California through mid week. A trough will move into the waters off Baja California Norte by mid week. This will tighten the pressure gradient and allow fresh westerly gap winds to funnel into the northern portion of the Gulf of California late Tue into Wed. Farther south, fresh to strong gap winds in the Gulf of Tehuantepec will diminish through today. Looking ahead, expect increased SW swell in the waters off southern Mexico by mid week. Swells generated by Linda are likely to cause life-threatening surf and rip current conditions along the coast of Baja California and southwest Mexico. Please consult products from your local weather office. 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 6 ft range in long period mixed swell. Mainly gentle winds will prevail north of the monsoon trough through early week. South of the monsoon trough, mainly moderate, occasionally fresh, S to SW winds will prevail through the middle of the week, supporting scattered showers and thunderstorms across the region. New southerly swell will impact the waters offshore of Ecuador tonight, 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. Hurricane Linda will impact the region from roughly 15N to 24N west of 120W through Thu as it continues to move westward. Gentle winds and moderate seas are evident north of this zone. Moderate SE winds and moderate SW swell are noted farther south. East of 110W, fresh SW monsoon flow is evident, with seas reaching 7 ft. For the forecast, moderate to locally fresh NW winds will follow a trough moving into the waters off Baja California by mid week. Long period NW swell will also follow this trough, reaching as far south as 27N after Wed. South of the monsoon trough and east of 110W, fresh to strong SW flow with reinforcing SW swell will allow seas to build to 9 ft through mid week. $$ ERA
