The forecasted rain and thunderstorms pose a risk of minor flooding and debris flows, particularly in areas with first-year burn scars, such as the Santa Monica Mountains, Palisades, and Altadena. Beach hazards, including rip currents and breaking waves, are expected to impact swimmers and surfers along south- and southwest-facing beaches in Los Angeles County, Oxnard, and San Diego County. Waves may also wash people off beaches and rocks or capsize small boats near the shore. Residents in flood-prone areas and beachgoers are advised to exercise caution during this period.
