Risk Overview

About Natural Disaster Risk in Copiah County, Mississippi

Copiah County Well Above National Risk

Copiah County scores 61.29 on the composite risk scale, earning a Relatively Low rating but sitting 20% above the national average. Central Mississippi residents face significantly elevated natural disaster exposure compared to typical American counties.

Among Mississippi's Higher-Risk Counties

Copiah County ranks in the upper third of Mississippi's 82 counties for overall disaster risk, with a composite score 20% above the state average of 50.94. Only the most hazard-prone counties in Mississippi exceed Copiah's exposure level.

Riskier Than Most Regional Counties

Copiah County's 61.29 score exceeds nearby Claiborne (24.75) and Clarke (36.04) counties substantially. It compares closely to Coahoma County (62.50), another high-risk area, and significantly exceeds Covington County (50.83) to the south, which sits near the state average.

Tornadoes, Hurricanes, and Floods Threaten

Copiah residents face extraordinary tornado risk at 89.47—among Mississippi's highest—plus elevated hurricane (78.06) and flood (46.69) risks. Wildfire exposure at 49.55 rounds out a notably comprehensive hazard profile well above state norms.

Multi-Hazard Insurance Coverage Critical

Homeowners need comprehensive coverage addressing tornadoes, hurricanes, and flooding, making this one of Mississippi's counties requiring the most robust insurance strategy. Separate flood insurance and tornado-resistant construction upgrades provide essential protection in this elevated-risk environment.

Risk Advisory: Copiah County

Risk Verdict

With a national percentile rank of 61th, Copiah County faces below-average hazard exposure relative to U.S. counties as a whole. Above-average risk does not mean imminent danger; it signals that informed, hazard-specific preparedness has high value here.

Hazard Breakdown

Tornado risk is Copiah County's dominant natural hazard, ranked at the 89th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 78th percentile nationally. Additional tracked hazards include earthquake (57th percentile), wildfire (50th percentile), flood (47th percentile).

Preparedness Context

At the 89th percentile nationally for tornado risk, Copiah 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 hurricane hazard at the 78th percentile nationally adds seasonal complexity to Copiah County's preparedness calendar, since hurricane and tornado risk often peak at different points in the year. For Copiah 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 10.4 points above the Mississippi state average, Copiah County carries meaningfully higher natural disaster exposure than a typical Mississippi county.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Copiah County higher risk than average?
Copiah County's composite risk score of 61th percentile is above the Mississippi state average of 51th percentile. This elevated risk is driven by tornado exposure (89th percentile), along with hurricane and earthquake risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
