| 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 and 100-hr fuel moisture 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 3-day average
(binned, not running) for the 1980-2004 period (heavy gray line).
The 90th and 97th percentile values are shown as solid back
horizontal lines. Seasonal traces for year-to-date (blue dashed
line) and other significant years (gold dashed line) may also
be shown. (Note: Some stations do not have data from 1980; what
is available is used). |

NOTE: Graphs
will generally be updated on Tuesdays (usually by 1600) through
June. From July through September the graphs will be updated
Sundays and Thursdays (by 1600). |
