Preparedness Context
Lea County sits at the 98th percentile for wildfire exposure. Signing up for Lea 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. Alongside wildfire, flood at the 88th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. In Lea 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.
