How likely is a tornado in Union County, MS?

Union County's EF4-5 history
Union County's record has no EF4-5 tornado - its 27 tracks split 12 weak and 15 significant. That does not rule one out in the future, only that none has been recorded since 1950.
What a storm shelter costs near Union County
Nationally, storm shelters and safe rooms run $2,890-$13,280. Because Union 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 outage nobody plans for
A direct hit is not required for Union County to lose power - outbreak-wide outages across Mississippi regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
Check your coverage, not just your risk
Because Mississippi allows wind/hail exclusions on standard homeowners policies, a Union 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. Union County covers about 416 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. Union County has about 28,363 residents.
