Major FEMA disasters in Iowa since 2016

The total includes 16 major disaster declarations: 9 for severe storms, 5 for floods, 1 for a tornado and 1 for a winter storm. The latest was in September 2026, and COVID-19 is not counted. A winter or ice storm accounted for 1; with a cold-weather kit, the engine keeps starting. Because 5 declarations involved floods, put the generator pad higher than the local flood level. Your permit office can provide that level for your lot.

The most frequently named locations are Mitchell County (7), Floyd County (6), Howard County (6), Polk County (6), Winneshiek County (6), Wright County (6), Allamakee County (5) and Buena Vista County (5).
