Today’s Fire Danger Indices (by FDRAs)

  • Observed and forecast values from WIMS. For use in determining Staffing Classes and Preparedness Levels.

Daily Fire Danger Rating & Seasonal ERC/BIs

ERCs and BIs are updated automatically for each station and Fire Danger Rating Area during the active fire season. These indices are generated through the WFAS system and can be different than the WIMS-generated indices, which are updated daily by Teton Interagency Dispatch in "Today's Fire Danger Indices" link above. Additional information at Great Basin 7 Day Outlook.

Duty Officers have the discretion to “step up” staffing for increased human caused risk, such as 4th of July, Pioneer Days, or opening of hunting season.

Local Fire Activity Guideline is defined as 2 or more Type 3 fires, or 1 or more type 1 or 2 fires or multiple initial attack fires.

When FDRAs indicate different Preparedness Levels, Duty Officers will determine Preparedness Levels by consensus. 


Fire Danger Adjective Rating Level

The TIF plan uses climatological breakpoints to determine adjective ratings. WIMs calculates Adjective Ratings using Staffing Level (SL) and Ignition Component (IC). The Teton Interagency Fire plan currently uses ERC Y and does not incorporate IC.
