Fuels / Fire Danger

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.

Staffing Level

III

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

Local Fire Activity	NO	YES	NO	YES	NO	YES	NO	YES
Preparedness Level	I	II		III		IV		V
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).

NFDRS Indices

Please note that we are now graphing NFDRS16 Y models to determine Preparedness, Staffing and Response Levels and Fire Danger Rating. See Today’s Fire Danger Indices (by FDRAs) or the charts below for current ERCs and BIs by FDRA zone.
