What a storm shelter costs near Mackinac County

The outage nobody plans for
Tornado outbreaks routinely knock out power across Michigan 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. Mackinac County covers about 1,022 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. Mackinac County has about 11,144 residents.
