Large NW swell is forecast to continue to spread offshore Baja California into the weekend, resulting in confused and hazardous seas as it mixes with swells generated by Norma. A broad area of low pres S of the Gulf of Tehuantepec near 08N95W is expected to gradually develop, and a tropical depression is likely to form during the next few days while the system meanders or drifts generally northward over the far eastern portion of the basin. $$ PMZ009-201530- Mexico Border S to 29N within 60 nm of shore- 826 PM PDT Thu Oct 19 2023 .TONIGHT...NW to N winds 15 to 20 kt.
