Risk Advisory: Macon County

Risk Verdict

Macon County sits in the lower tier of U.S. counties for natural disaster exposure, ranked at the 37th percentile nationally. Macon County residents can take confidence from a 37th percentile ranking, but even lower-risk counties benefit from a practiced household communication plan and awareness of the specific hazards listed above.

Hazard Breakdown

Tornado risk is Macon County's dominant natural hazard, ranked at the 66th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 54th percentile nationally. Additional tracked hazards include wildfire (53th percentile), flood (48th percentile), hurricane (21th percentile).

Preparedness Context

At the 66th percentile nationally for tornado risk, Macon 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 earthquake hazard at the 54th percentile nationally adds seasonal complexity to Macon County's preparedness calendar, since earthquake and tornado risk often peak at different points in the year. For Macon 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

Macon County falls 13.8 points below Missouri's typical county risk level, making it one of the safer natural-hazard environments in the state.
