FZPN27 KNHC 091537 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 837 AM PDT Thu Jul 9 2026 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. PMZ001-100345- Synopsis for the E Pacific within 250 nm of Mexico 837 AM PDT Thu Jul 9 2026 .SYNOPSIS...Ridging off Baja California is weakening as pressure lowers over the Colorado River Valley, allowing winds to diminish today, although NW swell to 8 ft will persist beyond 90 nm offshore through tonight. The pattern will also support fresh to strong S winds across the northern Gulf of California tonight through Fri night. Farther south, pulses of fresh to strong northerly gap winds across the Gulf of Tehuantepec through early next week. An area of low pressure is expected to form late this weekend or early next week several hundred miles south- southwest of the coast of southwestern Mexico. Environmental conditions appear favorable for gradual development thereafter, and there is a medium chance a tropical depression could form next week while the system moves generally west-northwestward. Regardless of tropical cyclone formation, the lowering pressure may induce at least fresh to strong winds and rough to very rough seas offshore of Oaxaca and Chiapas by Sun night, and off Guerrero by Mon night. $$ PMZ009-100345- Mexico Border S to 30N within 60 nm of shore- 837 AM PDT Thu Jul 9 2026 .TODAY...Variable winds less than 5 kt N of 31N, and W to NW 10 kt S of 31N.
