Check your coverage, not just your risk
Because Georgia allows wind/hail exclusions on standard homeowners policies, a Johnson County homeowner should confirm tornado wind damage is actually covered, not assume it - a separate endorsement is common here.
Read this before you rely on it
This is a county-level figure, not a per-address probability. Johnson County covers about 303 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. Johnson County has about 9,178 residents.
