Flood insurance is Lewis's main protection need

Hazard Breakdown

Flood risk is Lewis County's dominant natural hazard, ranked at the 69th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 47th percentile nationally.

Preparedness Context

With flood risk ranking at the 69th percentile nationally, Lewis County residents face one of the most financially damaging hazards without specialized coverage.

Secondary hurricane exposure at the 47th percentile adds a second preparedness layer; households should review coverage options and alert sign-up for both hazard types. Registering for Lewis County's county emergency alert system — typically through the county emergency management office's website — ensures households receive early warning when flood events develop faster than forecast.
