Walthall County, MS: Tornado Risk and Shelter Cost
Walthall County's tornado history, by the numbers
NOAA's Storm Prediction Center has recorded 33 tornado tracks touching Walthall County since 1957 - about one every 2.3 years on average. That puts it in our Elevated band nationally. Against the rest of the country, that is the 72nd percentile for frequency. Within Mississippi alone, Walthall County ranks 45 of 82 counties for tornado frequency.
Has Walthall County ever had a violent tornado?
Yes, 2 times: Walthall County has an EF4-5 tornado on record. Wherever that history exists, FEMA's safe-room case applies regardless of how often the county gets touched overall.
Paying for it, if Walthall County's history says you should
Nationally, storm shelters and safe rooms run $2,890-$13,280. Because Walthall County is in Mississippi, the Mississippi Emergency Management Agency's Safe Room Program can cut that by 75% (capped at $3,500), to about $722.5-$9,780 net - check current funding status before counting on it.
The gap a shelter does not cover
Tornado outbreaks routinely knock out power across Mississippi for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.
Check your coverage, not just your risk
Because Mississippi allows wind/hail exclusions on standard homeowners policies, a Walthall County homeowner should confirm tornado wind damage is actually covered, not assume it - a separate endorsement is common here.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Walthall County covers about 404 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. And records from before the 1990s, NOAA notes, undercount weaker tornadoes in areas with less storm-spotting coverage at the time. Walthall County has about 13,839 residents.
