The hazardous surf conditions pose significant risks to beachgoers, including strong rip currents and potential minor coastal flooding. Swimmers and surfers are advised to exercise extreme caution, as the rip currents can be life-threatening. Coastal areas may also experience localized flooding, particularly during high tide. The return of the high-pressure system later this week is expected to bring a heatwave, with temperatures in the San Fernando and San Gabriel valleys potentially exceeding 100°F (37.8°C).
