Monday June 17, Red Flag Warning. No Open Burning in Boulder County

Public Alert and Warning System

The Basics:

Why use warning over pre-evacuation or voluntary?

The types of wildfires we have that are devastating involve fast moving and escalating fires. The pre-evacuation or voluntary implies less urgency and that a second order or mandatory evacuation order is going to be made, in some cases the fire may be moving faster than information can be processed. If a resident receives only one alert it must elevate concern and if in doubt default to leaving the area not create an opportunity to stay. Getting people out is the goal and leaving a fire area prematurely does cause an imposition or disruption but public alerts and warning cannot be customized to each and every resident. Our goal is make sure an evacuation order goes out and gets you moving, if possible we will warn you of a possible evacuation order coming soon but if you are feeling uneasy or slightly in danger this is your time to leave.

Categories of Notifications

  • Advisories are used to share information about an emergency situation that is likely to impact community members.
  • Warnings are used to prepare people to take action, or take immediate action if you need extra time to mobilize (for example, if you have transportation or mobility limitations, large animals that need to be evacuated, etc).
  • Orders are used when action needs to be taken immediately due to an imminent life threat.
    • Examples of orders include Evacuation, Shelter in Place, Climb to Higher Ground.
  • All Clear- When there is no threat present and prior orders, warnings and advisories expire.
  • Missing Endangered Person is issued to alert the community and hopefully assist in locating the person.
  • Climb to Higher Ground Order is issued during a flash flood.
