The eastern extension of the monsoon trough remains inland over Costa Rica and Panama. The trough resumes near 10N111W to a 1008 mb low pres near 13N135W to 10N140W. Scattered moderate convection is noted within 240 nm on either side of the trough. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for information on Gale Warning in effect for the Tehuantepec region associated with the remnants of Tropical Depression Eleven-E. A trough is analyzed over the Tehuantepec region along 96W and N of 14N. This trough is associated to the remnants of T.D. Eleven-E. Elsewhere to the W of the Tehuantepec region, gentle to moderate NW to W winds prevail from Cabo Corrientes to the Revillagigedo Islands, where seas are 4 to 6 ft in mixed NW and SW swell. Scattered to numerous moderate to strong convection continues from 07N northward between 92W-102W. Across the waters offshore of Baja California, a very weak pressure pattern prevails, producing light to gentle mainly NW winds. Seas are 4 to 5 ft in NW swell, except 6 to 7 ft to the NW of Isla Guadalupe. Light to gentle winds, and seas of 1-3 ft, are found across the Gulf of California. For the forecast, the remnants of Tropical Depression Eleven-E will continue to move northward across southern Mexico through tonight accompanied by gale-force winds. Marine conditions will begin to improve quickly after midnight tonight. Scattered to numerous convection is expected to continue across the waters from Chiapas westward to offshore of Guerrero for the next few days, where winds and seas will be locally higher. Elsewhere, gentle NW to N winds will persist across the waters off Baja California throughout the week, with winds increasing to moderate speeds each late afternoon and evening near the coast. Looking ahead, broad low pressure may develop offshore of Colima and Jalisco early next week, producing increasing easterly winds and active weather along the coasts. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gentle to moderate onshore winds, and seas of 4-5 ft prevail across the majority of the discussion waters. The exception is across the waters of Guatemala and western El Salvador, where moderate to fresh S to SE winds and scattered showers and thunderstorms prevail. Seas across those waters are in the 5 to 5 ft range in westerly swell. For the forecast, moderate southwesterly winds and moderate to rough seas are expected offshore of Guatemala through midnight as the remnants of Tropical Depression Eleven-E moves slowly toward the coast of southern Mexico, and inland overnight. Otherwise, light to gentle W to NW winds are expected through Sat before a return to gentle to moderate SW to W winds occurs on Sun. ...REMAINDER OF THE AREA... A 1008 mb low is centered along the monsoon trough near 13N135W. Fresh to strong winds are noted in the vicinity of the low, where seas are in the 6-7 ft range. Light to gentle winds, and seas of 5-7 ft prevail N of the monsoon trough, except over the far NW waters, where moderate NE winds, and seas of 8-9 ft in mixed NW and NE swell prevail. S of the monsoon trough, moderate S to SW winds prevail, with seas in the 5-7 ft range. Moderate to rough seas in northerly swell over the waters north of 27N between 130W and 140W will gradually subside through the end of the week. The monsoon winds E of 120W, and the low along 13N135W drifting northward and weakening, will disrupt the typical trade wind pattern across the region S of 20N through the weekend. No significant swell event is expected across the regional waters through Mon. $$ ERA
