Risk Overview

About Natural Disaster Risk in Jefferson County, Kansas

Jefferson County Below National Disaster Risk

Jefferson County's composite risk of 19.66 places it in the Very Low category and below the national average. However, this understates the county's notable exposure to wildfires and flooding, which require household preparedness.

Safer Than Most Kansas Counties

At 19.66, Jefferson scores well below the Kansas average of 29.89, putting it in the state's safer tier. The county's below-average composite score masks above-average wildfire and flood risks.

Higher Risk Than Jackson, Lower Than Kingman

Jefferson (19.66) falls between Jackson (21.53) and Haskell (15.01), but its wildfire exposure at 67.72 exceeds most neighbors. This reflects the county's exposed position in Kansas's fire-prone northeast region.

Wildfires and Floods Top Jefferson's Risks

Wildfire (67.72) and flood (32.57) risks both exceed state averages, with tornadoes at 47.84 rounding out the top three. Spring flooding and fall/winter wildfire seasons drive most of the county's natural disaster exposure.

Bundle Wildfire, Flood, and Storm Coverage

Standard homeowner policies often exclude wildfire and flood damage—verify both are covered or add riders. Maintain gutters, trim branches overhanging your roof, and know your local flood zone and evacuation routes.

Preparedness Context

Jefferson County sits at the 68th percentile for wildfire exposure.

A secondary tornado exposure at the 48th percentile nationally means Jefferson County residents face hazards from two distinct natural peril categories during different seasons. In Jefferson County, wildfire smoke often precedes the flame front by hours or days; households benefit from tracking EPA's AirNow.gov and having HEPA air filtration available as a first line of indoor protection when air quality alerts are issued.
