The wetter conditions associated with El Niño increase flood risks, particularly in southern U.S. states. Homeowners without flood insurance may face significant financial losses, as standard policies exclude flood damage. Properties in FEMA-designated high-risk zones are especially vulnerable, with a 1% annual flood risk. Additionally, areas with wildfire burn scars are at heightened risk of debris flows during heavy rains. The lack of immediate coverage for new policies underscores the importance of proactive planning.
