Northern Rockies Predictive Services meteorologists monitor fire weather and National Fire Danger Rating System (NFDRS 16) components from a number of key stations in Idaho, Montana, Wyoming, and North Dakota and South Dakota. 

ERC, 1000-hr fuel moisture, 100-hr fuel moisture and Burning Index graphs are generated according to Predictive Service Areas (PSAs), which are geographic areas of similar climate/fuels based on statistical correlation of RAWS data.


For geographic comparison we are using Fuel Model Y and Fuel Model V, depending on applicablity. 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 are updated daily and show a trending average for the 2010-Present time 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/record years (orange line) may also be shown. (Note: Some stations do not have data for all representative years; what is available is used).
