Read this before you rely on it
This is a county-level figure, not a per-address probability. Mountrail County covers about 1,825 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. Mountrail County has about 9,474 residents.
