Lee County's EF4-5 history

What a storm shelter costs near Lee County

The outage nobody plans for
Power loss after a tornado outbreak in Illinois often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Lee County covers about 725 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. Lee County has about 33,544 residents.
