Emergency Alerts are utilized by all agencies within Larimer County to get vital life-saving information to the public quickly and efficiently. Emergency Alerts, commonly referred to as a reverse-911, are used when there is an imminent threat to life such as:

  • Missing endangered child (Amber Alert)
  • Missing endangered adult
  • Flooding
  • Wildfire
  • Police activity that would require you to evacuate or take shelter
  • Natural gas leaks
  • Severe threatening weather (rotation in clouds, large hail with cloud rotation, tornado warnings)

Why is it important to sign up for alerts?

  • By signing up you will be able to receive alerts to your mobile phone in the form of texts, voice calls and emails.
  • You can register multiple devices (cell phones, emails etc) and sign up for several different locations that are important to you (i.e. your child’s school or your elderly parent’s house)
