FINE FUEL MOISTURE CODE (DMC) |
This is a numerical rating of the moisture content of surface litter and other cured fine fuels.
It shows the relative ease of ignition and flammability of fine fuels. The moisture content of fine fuels is very
sensitive to the weather. Even a day of rain, or of fine and windy weather, will significantly affect the FFMC rating.
The system uses a time lag of two-thirds of a day to accurately measure the moisture content in fine fuels. The FFMC rating
is on a scale of 0 to 99. Any figure above 70 is high, and above 90 is extreme.
