Miller County sits at the 70th percentile for wildfire exposure. Signing up for Miller County's county emergency alert system and knowing the pre-planned evacuation route before conditions deteriorate are the two highest-value preparedness actions for residents here. The county's tornado exposure at the 69th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. In Miller County, wildfire smoke often precedes the flame front by hours or days; households benefit from tracking EPA's AirNow.gov and having HEPA air filtration available as a first line of indoor protection when air quality alerts are issued.
