Coastal communities along the U.S. West and East Coasts are at heightened risk of frequent and severe high tide flooding due to the anticipated El Niño. Elevated sea levels and stronger storm surges could lead to significant property damage, disruptions to transportation, and increased risks to public safety. The Gulf and Southeast Coasts may also experience higher-than-normal rainfall, compounding the risk of flooding. NOAA emphasizes the importance of preparedness, as the impacts of El Niño could be more pronounced than in previous years due to ongoing sea level rise.
