Hazard Breakdown

Tornado risk is Nobles County's dominant natural hazard, ranked at the 74th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 49th percentile nationally. Additional tracked hazards include earthquake (20th percentile), wildfire (20th percentile).

Preparedness Context

At the 74th percentile nationally for tornado risk, Nobles County households benefit most from a reliable alert system — a NOAA weather radio that activates during overnight hours when residents may not be checking smartphone alerts. The secondary flood hazard at the 49th percentile nationally adds seasonal complexity to Nobles County's preparedness calendar, since flood and tornado risk often peak at different points in the year. For Nobles County households, a pre-decided family shelter plan — who goes where, how children are retrieved from school during a warning, and a neighborhood meet-up point if phones fail — provides real protection that no supply kit alone can replicate.

Regional Context

At 7.8 points above the Minnesota state average, Nobles County carries meaningfully higher natural disaster exposure than a typical Minnesota county.
