Risk Overview

About Natural Disaster Risk in Boone County, Arkansas

Boone County moderately exposed to risks

Boone County's composite score of 62.34 sits above national averages, reflecting moderate exposure to natural disasters. The county's rating of "relatively low" indicates manageable but non-negligible hazard vulnerability.

Slightly above Arkansas average

Boone County's 62.34 exceeds the state average of 55.51, positioning it in the higher-risk tier within Arkansas. Tornado and wildfire exposure drive this elevation above the statewide baseline.

Riskier than Baxter but less than Benton

Boone County's 62.34 sits between Baxter County's 72.30 and Carroll County's 64.57, placing it in the moderate range for the region. Its Ozark location exposes it to similar tornado and wildfire risks as neighboring counties.

Tornado and wildfire dominate hazards

Tornado risk of 78.59 represents Boone County's most significant threat, with severe spring and fall storm systems regularly crossing the county. Wildfire risk of 65.59 ranks second, with forest coverage and seasonal drought conditions creating ignition potential.

Plan for storms and fires now

Develop a tornado safety plan with a designated shelter location, as the 78.59 tornado risk is substantial and recurring. Clear vegetation near structures, ensure adequate homeowners coverage for wind and fire damage, and maintain emergency supplies.

Risk Verdict

Boone County's FEMA risk score places it at the 62th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.

Hazard Breakdown

Tornado risk is Boone County's dominant natural hazard, ranked at the 79th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 71th percentile nationally. Additional tracked hazards include wildfire (66th percentile), flood (51th percentile), hurricane (37th percentile).

Preparedness Context

Tornado exposure at the 79th percentile nationally makes Boone County a county where a battery-powered weather radio — not just smartphone apps — is a worthwhile household investment, given that mobile networks often fail during severe storms. Earthquake is the second hazard driver for Boone County at the 71th percentile nationally, meaning households should maintain awareness of both severe-weather and earthquake-specific warning systems. In Boone County, tornado watches indicate favorable atmospheric conditions while warnings mean rotation has been detected — households benefit from understanding this distinction so they shelter immediately on a warning, not after seeking visual confirmation.

Regional Context

The Arkansas county average is 6.8 composite points below Boone County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
