California experienced severe storms over the past week, causing flash floods, mudslides, and power outages. The atmospheric rivers brought over 17 inches of rain and high winds to some areas, leading to four reported deaths, including a deputy killed in a crash and a man found in a submerged van. Ski resorts like Mammoth Mountain received significant snowfall, while over 50,000 homes initially lost power. Sunny skies are expected for the weekend, though gusty winds may pose further risks.
