Wildfire is the second hazard driver for Comanche County at the 93th percentile nationally, meaning households should maintain awareness of both severe-weather and wildfire-specific warning systems. The highest-risk window for tornado fatalities is overnight, when Comanche County residents may be asleep. A NOAA weather radio with overnight alert capability is the single most impactful low-cost preparedness step available to Comanche County households.
