Please refer to the Special Features section above for details on Tropical Storm Estelle a couple hundred NM southwest of Guerrero, Mexico. Away from the tropical storm, winds are gentle to locally moderate across the Mexican offshore and Gulf of California waters. Seas are 5-7 ft near the extreme northwestern Baja California Norte offshore waters. Seas continue to be 1-3 ft over the Gulf of California. In the Chiapas and Oaxaca offshore waters, winds are moderate to fresh from the E to SE, except in the Gulf of Tehuantepec where fresh to strong northerly winds are noted with seas to 6 ft. For the forecast, aside from the impacts from Tropical Storm Estelle, fresh to locally strong northerly winds will pulse across the Gulf of Tehuantepec through tonight, with moderate to fresh northerly winds prevailing through Tue. Otherwise, gentle to moderate winds will prevail across the rest of the Mexican offshores through early next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh NE winds are noted across the Gulf of Papagayo and rest of Nicaragua offshore waters. Elsewhere north of the monsoon trough, winds are light to gentle. South of the monsoon trough, S to SW winds are moderate to fresh. Seas are 5-7 ft over the Central American offshores and 5-8 ft over the equatorial zones. For the forecast, fresh to locally strong winds will pulse across the Gulf of Papagayo region and the coast of Nicaragua for the next few days. Elsewhere, winds will be tranquil through at least early next week. Large S to SW swell will continue to push north and build 9 ft by tonight. The swell is expected to subside by Tue morning. REMAINDER OF THE AREA... Weak ridging extends southeastward from a 1030 mb high near 38N159W to 20N120W. NE trades north of the ITCZ/monsoon trough are moderate to fresh with 5-7 ft seas. Northerly swell with seas to 8 ft are observed N of 29N between 120W and 125W. South of the monsoon trough, winds are moderate to fresh out of the S to SW. Seas are 7-10 ft with some S to SW swell being the primarily contributor. For the forecast, the NE trades and the S to SW monsoonal flow will change little over the next few days. By Tue night, Tropical Storm Estelle, expected to be of hurricane intensity at that point, will be moving over the high seas waters west of Clarion Island. The system should likely continue being a significant weather maker through at least the middle of next week. The large S to SW swell will continue progressing northeastward through the weekend and will subside by Tue. $$ Ramos
