National Fire Danger Rating System (NFDRS)

**ATTENTION KCFAST USERS**


The KCFAST application will be decommissioned by the end of the year. Users can still access KCFAST by using the (Legacy KCFAST) link. All KCFAST reports, data extracts and Batchout FTP site are now accessible under the new (Fire / Weather Data Extract) link. All KCFAST users are highly encouraged to begin using the new link before KCFAST is decommissioned and no longer available.

Please contact the IIA Help Desk with any problems.

On July 24, 2019, the NWCG Executive Board approved a proposal from the Fire Danger Subcommittee to update the initial NFDRS2016 Rollout Plan. All units will be fully transitioned to NFDRS2016 by January 2021.

The National Fire Danger Rating System (NFDRS) has offered a consistent interagency decision-support framework since its inception in 1972.  The System was first updated in 1978; and again in 1988.  Although the original developers intended for periodic improvements to be incorporated as science and technology improved, the System has remained fundamentally unchanged the past 40 years.  Today, there is even greater need for state-of-the-art tools to assist the wildland fire community sort through the daunting complexities and conflicting priorities which can confound decision-makers.  

In 2013, research scientists from the USDA Forest Service’s Rocky Mountain Research Station (RMRS) proposed updates to the National Wildfire Coordinating Group (NWCG) Fire Danger Subcommittee.  In September 2014, the NWCG Executive Board issued Memorandum 14-018, approving a revision to the US National Fire Danger Rating System.  Three significant changes were addressed:

Incorporate the Growing Season Index (GSI) to compute live fuel moisture; 
Incorporate the Nelson Model to compute fine dead fuel moisture; and 
Reduce the number of fuel models in the NFDRS. 
In September 2016, the NWCG Executive Board Issued Memorandum 16-019 providing an update of the transition to the 2016 version of NFDRS; otherwise known as NFDRS2016.  The primary objective is to provide a stable NFDRS2016 system along with updates to the Weather Information Management System (WIMS) and FireFamilyPlus (FF+) to assure end-users are comfortable with the new model outputs and associated applications.  

NFDRS2016 is a next-generation system which aligns with common interagency goals to use the best available science and technology to provide decision-makers with improved efficiencies, increased accuracy, and a much clearer understanding of the associated risks.  Since interagency cooperation and collaboration (at every level) is essential for a successful transition to NFDRS2016, all agencies (State and Federal) with responsibility to make and implement risk-based wildfire management decisions are encouraged to participate in the roll-out process.  

This web site has been designed to facilitate education regarding the new science and improve the utilization of NFDRS through the standard interagency applications of the system.

The National Fire Danger Rating System is supported by the National Wildfire Coordinating Group and monitored through their Fire Danger Sub Committee. All Federal, State and Local wildland fire management agencies are encouraged to work collaboratively with partners in their Dispatch Zones to create and adhere to a Fire Danger Operating Plan.

RMC Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters

Date:  May 28, 2026
Questions? 
Please contact: Risk Management Committee

The Risk Management Committee (RMC) has issued Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters. Research from 2016 to 2025 shows that 88 cases of rhabdomyolysis (rhabdo) were reported. Analysis of reports from eSafety, the Safety Management Information System (SMIS), and the Wildland Fire Lessons Learned Center (LLC) indicates that rhabdo is common during this time of year due to Work Capacity Tests and contributing factors such as weather, hydration, nutrition, and medication or supplement use.

RMC issued this safety bulletin to raise awareness in the Wildland Fire Community, and to provide research findings and educational resources that support reducing future cases of rhabdo.
