See TN hazardsTN hazard profile
Tennessee averages 15 tornadoes per year but experiences significant outbreak events. The 2020 Nashville tornado killed 25 people and caused $1.5B in damage. Middle Tennessee is the most active corridor. Tornadoes can occur in any season here — December and January outbreaks are not unusual. Every major Tennessee river — the Cumberland, Tennessee, Mississippi, Harpeth — has a history of catastrophic flooding. The 2010 Nashville flood (17 inches in two days) killed 21 people and caused $2B in damage. Flash flooding in mountain coves and hollows is fast and deadly. The January 2026 winter storm hit 29 counties and triggered a federal major disaster declaration. FEMA Disaster Unemployment Assistance opened for affected counties. East Tennessee and the Cumberland Plateau are the most ice-prone; even Nashville freezes several times per decade.
Occur across most of the state, often embedded in severe thunderstorm lines and tropical systems.

Not in your standard policy
Flood damage — requires NFIP or private flood policy
Earthquake damage — requires separate endorsement
Sewer & drain backup — requires endorsement ($50–$100/yr)
Landslide / mudflow — generally excluded
