PMZ001-191500- Synopsis for the E Pacific within 250 nm of Mexico 751 PM PDT Sun Jul 18 2021 .SYNOPSIS...Tropical Storm Guillermo near 18.9N 115.6W 1001 mb at 8 PM PDT moving W at 13 kt.

A moderate NW swell may impact the waters offshore of Baja California Norte toward the end of the week. Elsewhere, tranquil conditions will prevail in the wake of Guillermo for the next several days. $$ PMZ009-191500- Mexico Border S to 29N within 60 nm of shore- 751 PM PDT Sun Jul 18 2021 .TONIGHT...NW winds 10 to 15 kt.
