What a storm shelter costs near Antrim County

The outage nobody plans for
The storm that misses Antrim County outright can still take its power out - outbreak-scale outages across Michigan 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. Antrim County covers about 476 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. Antrim County has about 24,536 residents.
