PMZ001-172030- Synopsis for the E Pacific within 250 nm of Mexico 128 AM PDT Sat Jul 17 2021 .SYNOPSIS...A broad area of low pressure southwest of the coast of southwestern Mexico is gradually becoming better organized. The low is forecast to move west-northwest to westward toward the Revillagigedo Islands through early Mon. This may bring increasing winds and building seas to the offshore waters from Oaxaca to Jalisco through late Sat, and into the Revillagigedo Islands Sat night through early Mon. This low has a high chance of tropical cyclone formation and a gale warning is in effect. Fresh to strong gap winds will pulse at night in the Tehuantepec region. Mainly gentle to moderate winds will prevail elsewhere. $$ PMZ009-172030- Mexico Border S to 29N within 60 nm of shore- 128 AM PDT Sat Jul 17 2021 .TODAY...NW winds 10 kt. Seas 3 to 5 ft.
