Individual waves may be more than twice the significant wave height. PMZ001-011030- Synopsis for the E Pacific within 250 nm of Mexico .SYNOPSIS...The Picaya volcano in southern Guatemala near 14.4N 90.6W is currently erupting. A plume of volcanic ash that is spreading southwestward over the offshore waters of Guatemala and far southeastern Mexico may reach the surface of the ocean through at least Thu morning over the far eastern part of the Gulf of Tehuantepec region offshore waters. Otherwise, moderate winds across the Gulf of Tehuantepec will abruptly become strong gale force north to northeast winds beginning late tonight into early Thu as a cold front quickly moves over the western Gulf of Mexico and across southeastern Mexico. These gale conditions are expected to continue into the upcoming weekend, diminishing to just below gale force Sun afternoon. Swell generated by this event will spread well to the southwest and west of the Gulf of Tehuantepec region through the weekend. $$ PMZ009-011030- Mexico Border S to 29N within 60 nm of shore- 329 PM PDT Wed Mar 31 2021 .TONIGHT...NW to N winds 10 kt.
