Peoria County's EF4-5 history

What a storm shelter costs near Peoria County
For a Peoria County homeowner, budget $2,890-$13,280 for a shelter or safe room ($7,645 typical) - this pass found no Illinois-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 Illinois 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. Peoria County covers about 619 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. Peoria County has about 179,630 residents.
