Allen County's EF4-5 history
Allen 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 Allen County
For a Allen County homeowner, budget $2,890-$13,280 for a shelter or safe room ($7,645 typical) - this pass found no Ohio-specific rebate on top of FEMA's underlying 75% national cost-share program.
The outage nobody plans for
Tornado outbreaks routinely knock out power across Ohio 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.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Allen County covers about 403 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. Allen County has about 100,866 residents.
