Whiteside County's EF4-5 history

What a storm shelter costs near Whiteside County
For a Whiteside 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
The storm that misses Whiteside County outright can still take its power out - outbreak-scale outages across Illinois are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Whiteside County covers about 684 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. Whiteside County has about 54,657 residents.
