Daviess County's EF4-5 history

What a storm shelter costs near Daviess County

Read this before you rely on it
This is a county-level figure, not a per-address probability. Daviess County covers about 563 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. Daviess County has about 8,541 residents.
