The anticipated El Niño could lead to flash floods, debris flows in burn scar areas, severe thunderstorms, and coastal erosion in Southern California. Beach communities are particularly vulnerable to high surf and dangerous rip currents. The increased rainfall may also exacerbate risks for those living in flood-prone zones or near unstable hillsides. Additionally, the ongoing heatwave linked to El Niño could have severe health impacts, with global heat-related fatalities projected to rise significantly. Residents are urged to prepare for both immediate and long-term weather challenges.
