Today’s Fire Danger Indices (by FDRAs)
Observed and forecast values from WIMS. For use in determining Staffing Classes and Preparedness Levels.

Fire Danger Rating Adjective Descriptions

Daily Fire Danger Rating & Seasonal ERC/BIs 

ERCs and BIs 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 in "Today's Fire Danger Indices" link above. Additional information at Great Basin 7 Day Outlook.
