Columbia County scores 81.42, earning a Relatively Moderate risk rating that stands well above Wisconsin's average of 59.08. This score reflects elevated exposure to multiple natural hazard types compared to most U.S. counties.
Columbia among Wisconsin's riskiest

Tornadoes, floods, and wildfires converge
Columbia's tornado risk peaks at 75.73, flood risk reaches 75.60, and wildfire risk stands at 42.30—a triple threat that sets this county apart from lower-risk neighbors. Earthquake risk (28.72) and even hurricane exposure (10.60) are elevated for Wisconsin.

Hazard Breakdown
Tornado risk is Columbia County's dominant natural hazard, ranked at the 76th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 76th percentile nationally. Additional tracked hazards include wildfire (42th percentile), earthquake (29th percentile), hurricane (11th percentile).
Preparedness Context
At the 76th percentile nationally for tornado risk, Columbia 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. Alongside tornado exposure, flood at the 76th percentile nationally means Columbia County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. For Columbia 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 22.3 points above the Wisconsin state average, Columbia County carries meaningfully higher natural disaster exposure than a typical Wisconsin county.
