Southern California is bracing for a series of storms predicted to deliver much-needed rain this week, including the first atmospheric river storm of the season. As conditions shift, the region can expect heavy rainfall and gusty winds, starting with a moderate rainstorm on Tuesday. Residents are being urged to prepare for potential hazards, particularly in areas affected by recent wildfires where mudslide risks are heightened. With forecasts indicating back-to-back storm systems and the possibility of intense weather, officials are recommending that homeowners take precautions to safeguard their properties against flooding and debris flows. The upcoming downpours have raised concerns about toxic runoff and the challenges of rebuilding after devastating blazes, signaling a critical period for both communities and emergency responders.
