Updated Offshore Waters Sections ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: A 1024 mb high moving from northern Mexico into the Gulf of Mexico will channel fresh to strong northerly winds through the Chivela Pass in southern Mexico. In response, northerly gap winds at the Gulf of Tehuantepec will reach near-gale to gale- force this evening, and then persist until late Tuesday night. Seas under these winds are expected to peak between 15 and 17 ft. As the high shifts to the eastern Gulf of Mexico on Wed, both winds and seas at the Gulf of Tehuantepec will gradually subside. Marine interests in the area need to monitor this situation closely and plan their route accordingly. Please read the latest High Seas and Offshore Waters Forecasts issued by the National Hurricane Center at the website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and https://www.nhc.noaa.gov/marine/offshores_eastpac.php for more details Significant NW Swell: Large, long-period NW swell produced by fresh to strong winds off the U.S. west coast are propagating southeastward across the tropical eastern Pacific. This swell will cause very rough seas of 12 to 18 ft west of a line from 30N123W to 23N120W to 03N140W through Thu evening. Sea should gradually subside starting Fri as this swell steadily decay. Please read the latest High Seas Forecasts issued by the National Hurricane Center at the website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... An equatorial trough extends from 09N79W to 04N90W to 05N105W. Widely scattered showers are present near up to 50 nm south of the trough east of 94W. An ITCZ extends from 05N105W to 07N123W, then from 07N126W to beyond 140W at 04N. Scattered moderate convection is seen up to 50 nm along either side of the first ITCZ segment, and up to 130 nm north, and 80 nm south of the second segment. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... See the Special Features Section for information on a gale warning for the Gulf of Tehuantepec. A 1016 mb high pressure is centered at 23N117W near the Revillagigedo Islands. The pressure gradient between this high pressure and a cold front off Baja California Norte is supporting moderate SW to W winds with 5 to 8 ft seas across the offshore waters of Baja California Norte and northern Gulf of California. Gentle to moderate northerly winds and seas at 4 to 6 ft prevail over the waters off Baja California Sur and southern Gulf of California. Light to gentle winds and seas of 6 to 8 ft in moderate NW swell exist off the central and southern Mexico coast, except the Gale Warning area. For the forecast, fresh to strong SW to W winds behind a cold front are expected in the far northern Gulf of California from early Tue morning through Thu morning. Fresh with locally strong northerly winds are anticipated for the Baja California offshore waters Tue afternoon through Wed morning. Large, long-period NW swell will enter the offshore waters of Baja California Norte on Tue, and Baja California Sur on Wed. Rough seas caused by this swell will persist through Fri before improving this weekend. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR Gentle to moderate W to NW winds exist offshore from Guatemala southeastward to Panama. Besides 6 to 8 ft seas in moderate northerly swell offshore from Guatemala and El Salvador, 3 to 5 ft seas are present in the same area. Light to gentle winds and seas of 3 to 4 ft in mixed moderate swells dominate waters off Colombia, Ecuador and the Galapagos Islands. For the forecast, large northerly swell generated by gap winds at the Gulf of Tehuantepec is going to cause rough seas at the far western offshore waters of Guatemala and El Salvador this evening through Wed morning. Fresh to strong gap winds will develop in the Papagayo region by Tue night, and Gulf of Panama by Wed. Mainly gentle winds and moderate seas are expected for the remaining offshore waters into the weekend. ...REMAINDER OF THE AREA... See the Special Features Section for information on an ongoing large swell event. Aside from the large swell, a cold front extends from a 1010 mb low near the Channel Islands, California across 23N124W to 14N136W. A 1033 mb high is centered northwest of the area near 34N149W. The pressure gradient between this high and the cold front is supporting fresh to strong northerly winds over the waters northwest of the cold front. Gentle to moderate winds generally prevail west of 110W, with mainly light to gentle winds east of 110W. Seas in both areas range from 5 to 7 ft in mixed moderate swells. For the forecast, fresh to strong trade winds will develop north of the ITCZ early this week as high pressure builds over the area in the wake of the front. $$ Chan
