Risk Overview
About Natural Disaster Risk in Grundy County, Missouri
Grundy County ranks well below national risk
At 27.86, Grundy County's composite risk score places it in the "very low" category and substantially below the national baseline. This favorable profile reflects a fortunate geographic position away from major seismic zones and hurricane paths.
Among Missouri's lowest-risk counties
Grundy County scores 27.86, placing it well below Missouri's state average of 50.56 and in the bottom tier of the state's 114 counties. Its consistent, moderate hazard exposure across all categories contributes to this safety ranking.
Safe within a relatively low-risk region
Grundy County's 27.86 score aligns with neighboring Gentry County (28.85) and other north-central Missouri counties that sit in a low-risk band. This makes the broader region one of Missouri's safest.
Tornado risk moderately elevated locally
Tornado risk at 64.69 is Grundy County's highest hazard, though it remains below the state average for tornado risk overall. Wildfire risk (46.79), flood risk (30.25), and earthquake risk (30.66) are all well-controlled; hurricane risk is minimal (14.48).
Standard homeowners coverage is appropriate
With very-low-risk standing, a standard homeowners policy including wind and hail coverage addresses Grundy County's primary exposures. Focus your preparedness efforts on tornado safety—a weather radio and safe-room plan—rather than specialized insurance products.

Risk Verdict
Grundy County sits in the lower tier of U.S. counties for natural disaster exposure, ranked at the 28th percentile nationally. Grundy County's 28th percentile ranking is favorable, though every county carries at least one natural hazard worth knowing — reviewing the specific risks listed above helps households focus their preparedness where it matters most.
Hazard Breakdown
Tornado risk is Grundy County's dominant natural hazard, ranked at the 65th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 47th percentile nationally. Additional tracked hazards include earthquake (31th percentile), flood (30th percentile), hurricane (14th percentile).
Preparedness Context
At the 65th percentile nationally for tornado risk, Grundy 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 wildfire hazard at the 47th percentile nationally adds seasonal complexity to Grundy County's preparedness calendar, since wildfire and tornado risk often peak at different points in the year. For Grundy 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
Grundy County falls 22.7 points below Missouri's typical county risk level, making it one of the safer natural-hazard environments in the state.
