|Class Ignition Potential||Interpretation|
|Low||Low probability of fire starts.|
|Medium||Moderate probability of fire starts in areas of local dryness.|
|High||Grass fuels becoming easily ignitable. Higher probability of fire starts.|
|Extreme||Grass fuels highly flammable. Very high probability of fire starts.|
The FFMC values shown on the map are numerical ratings of the moisture content of litter and other cured fine fuels. The FFMC values are used to indicate the flammability of fine fuels and the relative ease of ignition.
