Storm surge and tide impacts. Illustration of water level differences for storm surge, storm tide, and a normal high tide, as compared to sea level. Storm surge is the rise in sea level caused solely by a storm. Storm tide is the total observed sea level during a storm, which is the combination of storm surge and normal high tide.

Hurricane Michael caused widespread destruction along the Florida Panhandle, including in Mexico Beach, Florida, October 2018.
