Risk Overview

About Natural Disaster Risk in Cherokee County, Iowa

Cherokee County ranks very low nationally

Cherokee's composite risk score of 34.13 places it well below both Iowa's state average (39.68) and the national average, indicating relatively modest disaster exposure. This county experiences fewer natural hazards than most American regions.

Among Iowa's safest counties

Cherokee ranks in the lower third of Iowa's 99 counties by composite risk, with a score that reflects below-average exposure to most major hazard types. It remains one of the state's more stable communities from a natural disaster perspective.

Comparable risk to surrounding counties

Cherokee's 34.13 score aligns closely with Chickasaw (31.74) and Clay (36.39), reflecting similar risk profiles across this region of north-central Iowa. All three counties share relatively low hazard exposure compared to state averages.

Tornado risk slightly elevated

Cherokee's tornado risk of 60.75 represents the county's primary natural hazard exposure, though still below state problematic levels. Flood risk (39.06) and wildfire risk (24.46) remain modest, with earthquake activity minimal.

Focus on tornado preparedness

While Cherokee faces lower overall disaster risk, tornado coverage gaps in standard policies make windstorm insurance a practical safeguard. Identify a basement shelter or safe interior room as your family's tornado refuge.

Risk Advisory: Cherokee County

Risk Verdict

At the 34th percentile nationally, Cherokee County experiences relatively limited natural hazard pressure compared to most of the country. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at Cherokee County's favorable 34th percentile ranking.

Hazard Breakdown

Tornado risk is Cherokee County's dominant natural hazard, ranked at the 61th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 39th percentile nationally. Additional tracked hazards include wildfire (24th percentile), earthquake (11th percentile).

Preparedness Context

Cherokee County ranks at the 61th percentile nationally for tornado exposure. Unlike many slow-onset hazards, tornadoes in Cherokee County can reach full intensity in minutes; a pre-practiced household shelter plan matters far more than stockpiled supplies. The secondary flood hazard at the 39th percentile nationally adds seasonal complexity to Cherokee County's preparedness calendar, since flood and tornado risk often peak at different points in the year. Cherokee County county emergency management typically publishes annual severe-weather preparedness guides tailored to local tornado patterns; households benefit from reviewing these before storm season begins each spring.

Regional Context

A composite score 5.5 points below the Iowa state average puts Cherokee County in a better-than-typical position relative to neighboring counties.
