Similar risks to nearby Chippewa

Tornadoes and floods dominate the threat
Clark's tornado risk reaches 71.69 and flood risk stands at 69.12, positioning these two hazards as the county's primary natural disaster concerns. Wildfire risk is minimal at 19.78, while earthquake (14.12) and hurricane (0.00) threats remain negligible.
Windstorm and flood coverage essential here
