Simpson County, MS Tornado Risk & Storm Shelter Cost
Simpson County's tornado history, by the numbers
Since 1953, NOAA has logged 77 tornado tracks crossing Simpson County - one about every year, which lands it in our High band.

Simpson County's EF4-5 history
Simpson County has 5 violent (EF4-5) tornados on record. FEMA centers its safe-room case on exactly this strength, not on how often a county gets touched - a hardened room is the difference between a code-built house surviving an EF4-5 or not.
What a storm shelter costs near Simpson County
A storm shelter or in-residence safe room typically runs $2,890-$13,280 nationally (around $7,645 typical). Mississippi's Mississippi Emergency Management Agency's Safe Room Program covers 75% of an approved project, up to $3,500 - bringing a typical job down to roughly $722.5-$9,780 out of pocket, when the program is currently funded.
The outage nobody plans for
25,597 people live in Simpson County, and a tornado outbreak's power loss usually reaches far more of Mississippi than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
Check your coverage, not just your risk
Because Mississippi allows wind/hail exclusions on standard homeowners policies, a Simpson County homeowner should confirm tornado wind damage is actually covered, not assume it - a separate endorsement is common here.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Simpson County covers about 589 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. Pre-radar-era records (before the 1990s) are also documented by NOAA as undercounting weaker tornadoes in sparsely-instrumented areas. Simpson County has about 25,597 residents.
