Gibson County's EF4-5 history
Gibson County has 1 violent (EF4-5) tornado 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 Gibson County
Nationally, storm shelters and safe rooms run $2,890-$13,280. Because Gibson County is in Indiana, the Indiana Department of Homeland Security's Residential Safe Room Program can cut that by 75% (capped at $5,000), to about $722.5-$8,280 net - check current funding status before counting on it.
The outage nobody plans for
A direct hit is not required for Gibson County to lose power - outbreak-wide outages across Indiana regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Gibson County covers about 487 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. Gibson County has about 33,038 residents.
