Risk Overview

About Natural Disaster Risk in Holmes County, Mississippi

Holmes County sits near average national risk

Holmes County's composite risk score of 49.81 places it as relatively low nationally, just slightly below Mississippi's state average of 50.94. The county's balanced exposure across hazard types keeps it from concentrating risk in any single category.

Middle-of-the-road risk for Mississippi

Holmes County ranks roughly in the middle of Mississippi's county risk distribution, neither significantly safer nor more exposed than typical state communities. Most Mississippi counties cluster near this risk level, making Holmes representative of average state exposure.

Comparable risk to surrounding counties

Holmes County's score of 49.81 aligns closely with neighboring Humphreys County (27.93) and Yazoo County, reflecting the central Mississippi Delta region's mixed hazard profile. The area faces moderate tornado and earthquake exposure balanced against lower flood risk.

Tornadoes demand priority attention

Tornado risk of 82.47 emerges as Holmes County's dominant hazard, roughly 60% higher than the county's overall composite score. Earthquake (69.72) and hurricane (66.46) risks follow, creating a diverse disaster threat landscape across seasons.

Build tornado preparedness into your plan

With tornado risk outpacing other hazards, Holmes County households should prioritize safe-room construction or access to community shelters as the foundation of disaster readiness. Pair this with flood insurance—often overlooked but essential in Delta communities—and your family becomes significantly more resilient.

Risk Verdict

Holmes County ranks at the 50th percentile nationally for natural disaster risk — below the median for U.S. counties. The 50th percentile national ranking is one lens; Holmes County residents also benefit from reviewing which specific hazard types drive the county's composite score and preparing accordingly.

Hazard Breakdown

Tornado risk is Holmes County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 70th percentile nationally. Additional tracked hazards include hurricane (66th percentile), wildfire (57th percentile), flood (32th percentile).

Preparedness Context

Holmes County ranks at the 82th percentile nationally for tornado exposure. Unlike many slow-onset hazards, tornadoes in Holmes County can reach full intensity in minutes; a pre-practiced household shelter plan matters far more than stockpiled supplies. Alongside tornado exposure, earthquake at the 70th percentile nationally means Holmes County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. Holmes County county emergency management typically publishes annual severe-weather preparedness guides tailored to local tornado patterns; households benefit from reviewing these before storm season begins each spring.

Regional Context

The county's composite score diverges by only 1.1 points from the Mississippi average, making Holmes County's hazard profile broadly typical for this part of the state.
