Risk Overview

About Natural Disaster Risk in Moody County, South Dakota

Moody County carries minimal national risk

Moody County's composite risk score of 26.94 places it just above the South Dakota state average of 26.84, indicating very low overall disaster exposure compared to U.S. counties. The county sits well below the national risk median, offering residents relatively stable conditions across most hazard categories.

Safest counties in South Dakota

Moody County ranks among the bottom tier of disaster-prone South Dakota counties, with a composite score essentially matching the state average. This position reflects manageable exposure to natural hazards, though localized tornado and wildfire risks still warrant standard preparedness measures.

Dramatically safer than nearby Minnehaha

Moody County's 26.94 score represents roughly one-third the risk of neighboring Minnehaha County's 89.54, making it one of South Dakota's safest regions despite proximity to higher-risk areas. This geographic variance means disaster preparedness needs differ sharply even between adjacent counties.

Tornado and wildfire present modest threats

Tornado risk in Moody reaches 62.91, representing the county's primary hazard concern but still well below national highs for this category. Wildfire risk of 54.04 ranks as the second concern, though neither threat approaches the severity found in counties west of the Missouri River.

Standard coverage provides adequate protection

Moody County residents benefit from low-risk exposure, making standard homeowners insurance with tornado coverage sufficient for most properties. Review your policy annually to ensure adequate liability and replacement-cost coverage, and maintain a weather radio to receive storm warnings during tornado season.

Risk Verdict

Natural disaster exposure in Moody County is lower than roughly three-quarters of U.S. counties, with a composite score at the 27th percentile. Moody County residents can take confidence from a 27th 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 Moody County's dominant natural hazard, ranked at the 63th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 54th percentile nationally. Additional tracked hazards include flood (26th percentile), earthquake (13th percentile).

Preparedness Context

Ranked at the 63th percentile nationally for tornado risk, Moody County is in a zone where storm shelters have the highest per-dollar protective value of any mitigation investment. Moody County's county shelter map is typically available through the local emergency management office. The secondary wildfire hazard at the 54th percentile nationally adds seasonal complexity to Moody County's preparedness calendar, since wildfire and tornado risk often peak at different points in the year. Moody County residents can check the county's emergency management website for community shelter locations nearest their address — a step worth completing now, not during a warning.

Regional Context

Moody County's composite risk score is within 0.1 points of the South Dakota county average — a close alignment that reflects a broadly representative hazard environment for this part of the state.
