Preparedness Context
Tornado exposure at the 66th percentile nationally makes Green County a county where a battery-powered weather radio — not just smartphone apps — is a worthwhile household investment, given that mobile networks often fail during severe storms. Alongside tornado exposure, flood at the 44th percentile nationally means Green County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. In Green County, tornado watches indicate favorable atmospheric conditions while warnings mean rotation has been detected — households benefit from understanding this distinction so they shelter immediately on a warning, not after seeking visual confirmation.
Regional Context
At 12.7 points below the Wisconsin state average, Green County is among the lower-risk counties in the state for natural disaster exposure.
