The wetter conditions associated with El Niño could increase the risk of flooding, particularly in areas prone to drainage issues or with a history of landslides. Northern California faces additional risks from rain-on-snow events, where rain falling on existing snowpack could lead to rapid runoff and flooding in lower elevations. These conditions may also strain rivers and reservoirs. Homeowners and property managers are advised to prepare for potential storm impacts by reviewing drainage systems, updating insurance coverage, and addressing deferred maintenance.
