Madison County registers a moderately elevated natural disaster risk, ranking at the 82th percentile across all U.S. counties. High composite risk signals that multiple hazard types are elevated simultaneously; planning for more than one scenario is important in Madison County.

Hazard Breakdown

Tornado risk is Madison County's dominant natural hazard, ranked at the 96th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 78th percentile nationally.

Preparedness Context

Madison County's primary hazard, tornado, ranks at the 96th percentile nationally. In Madison County, mobile homes and manufactured housing face significantly higher tornado risk than site-built structures; residents in these homes should identify the nearest permanent community shelter in advance. The secondary hurricane hazard at the 78th percentile nationally adds seasonal complexity to Madison County's preparedness calendar, since hurricane and tornado risk often peak at different points in the year. The highest-risk window for tornado fatalities is overnight, when Madison County residents may be asleep. A NOAA weather radio with overnight alert capability is the single most impactful low-cost preparedness step available to Madison County households.

Regional Context

Madison County falls 31.2 points above Mississippi's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.
