NRCC monitors fire weather and National Fire Danger Rating System (NFRDS) components from a number of key stations in Idaho, Montana, Wyoming, and North and South Dakota. ERC, 1000-hr fuel moisture, 100-hr fuel moisture and Burning Index graphs are generated by Predictive Service Areas within the Northern Rockies Geographic Area. Predictive Service Areas (PSAs) are geographic areas of similar climate based on statistical correlation of RAWS data.
 
For geographic comparison we are using Fuel Model G (1978) at all stations. ERC and 1000-hr fuel moisture are stable indexes that do not jump around from day-to-day, whereas 100-hr fuel moisture is more variable. All are good for monitoring the fire season.
   
The graphs show a daily average for the 1998-2013 period (heavy gray line). The 90th and 97th percentile values are shown as solid back horizontal lines. Seasonal traces for year-to-date (blue line) and other significant years (orange line) may also be shown. (Note: Some stations do not have data for all representative years; what is available is used).
   
NOTE: (Graphs will updated daily April through October)
