Brown County's EF4-5 history

What a storm shelter costs near Brown County

The outage nobody plans for
A direct hit is not required for Brown County to lose power - outbreak-wide outages across Ohio regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Brown County covers about 490 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. Brown County has about 44,292 residents.
