Southern California is set to experience a significant shift in weather as two storms approach this week, bringing moderate to heavy rain and mountain snow. The region, which faced a delayed rainy season, is now preparing for potentially hazardous conditions, including mudslides and flooding, particularly in areas with wildfire burn scars. With inches of rain and feet of snow anticipated, water managers are on alert as the storms, fueled by atmospheric rivers, are expected to impact various counties, including Ventura and Pasadena. Evacuation warnings have been issued in some areas, and residents are advised to brace for strong winds and significant weather fluctuations throughout the week.
