Northern California will face heavier rainfall, while Southern California will experience lighter showers. Gusty winds may impact inland areas, and minor flooding is possible over the weekend. Coastal regions should prepare for dangerous rip currents and high surf conditions, with waves reaching up to 12 feet. Swimmers are advised to stay near lifeguards and avoid rock jetties. The storms may briefly strengthen due to warm ocean waters, increasing the potential for thunderstorms and heavy downpours.
