Risk Overview

About Natural Disaster Risk in Decatur County, Georgia

Decatur faces elevated national disaster risk

Decatur County scores 75.86 on composite risk, nearly double the national average and placing it in the Relatively Low category. The county's location in southwest Georgia and proximity to coastal weather patterns creates above-average exposure to multiple hazard types.

Among Georgia's riskier counties

Decatur's 75.86 score significantly exceeds Georgia's state average of 39.49, ranking the county in the upper tier of Georgia risk. This elevated position reflects the county's vulnerability to hurricanes, tornadoes, and flooding.

Riskiest county in its immediate area

Decatur stands out among southwest Georgia neighbors, scoring substantially higher than Dodge County (44.75) and Dooly County (14.95) to the north. The county's coastal proximity and relative flatness distinguish it from neighboring inland counties.

Hurricanes and tornadoes dominate the threat picture

Hurricane risk reaches 90.53—Decatur's highest hazard and among the highest in the state—while tornado risk scores 80.82. Flood risk (76.97) rounds out the major threats, making Decatur vulnerable to multiple severe weather events.

Comprehensive coverage is essential for Decatur

Decatur residents must carry robust homeowners insurance with hurricane, tornado, and wind coverage, and should carefully evaluate flood insurance given the 76.97 flood risk score. Securing window protection, roof reinforcement, and backup power systems offers practical protection against the county's primary hazards.

Risk Advisory: Decatur County

Risk Verdict

Decatur County's FEMA risk score places it at the 76th percentile nationally, indicating lower-than-typical exposure for a U.S. county. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Decatur County residents.

Hazard Breakdown

Hurricane risk is Decatur County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 81th percentile nationally. Additional tracked hazards include flood (77th percentile), wildfire (64th percentile), earthquake (40th percentile).

Preparedness Context

With hurricane ranked at the 91th percentile nationally, Decatur County sits in a zone where multi-day supply readiness matters: grid outages after landfalling storms can last one to three weeks in heavily affected areas. Decatur County's tornado exposure at the 81th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Insurance gaps are the most common post-hurricane financial shock: standard homeowners policies typically exclude flood damage and may have a separate wind deductible. Decatur County households benefit from a pre-season insurance review confirming both wind and flood coverage.

Regional Context

The Georgia county average is 36.4 composite points below Decatur County's score, a gap that reflects the county's elevated position in the state's hazard distribution.

Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Decatur County higher risk than average?
Decatur County's composite risk score of 76th percentile is above the Georgia state average of 40th percentile.
