A broad area of low pressure is expected to form in a few days a couple of hundred miles south of the coast of southern Mexico. Environmental conditions are expected to be conducive to support some development thereafter, and a tropical depression could form late this week or this weekend while the system moves west- northwestward to northwestward near or just south of the coast of southern Mexico. Farther north, new NW long period swell will start to move into the waters near Guadalupe Island by Thu, bringing seas in excess of 8 ft to all the offshore waters of Baja California Fri and Sat. $$ PMZ009-190930- Mexico Border S to 29N within 60 nm of shore- 220 PM PDT Mon Oct 18 2021 .TONIGHT...NW winds 10 to 15 kt.
