Tornado outbreaks routinely knock out power across Tennessee 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. Shelby County covers about 753 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. Shelby County has about 910,530 residents.
