Read this before you rely on it
This is a county-level figure, not a per-address probability. Foster County covers about 634 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. Foster County has about 3,323 residents.
