Fire danger is a relative index of how easy it is to ignite vegetation, how difficult a fire may be to control, and how much damage a fire may do.
|Low||Fires likely to be self-extinguishing and new ignitions unlikely. Any existing fires limited to smoldering in deep, drier layers.|
|Moderate||Creeping or gentle surface fires. Fires easily contained by ground crews with pumps and hand tools.|
|High||Moderate to vigorous surface fire with intermittent crown involvement. Challenging for ground crews to handle; heavy equipment (bulldozers, tanker trucks, aircraft) often required to contain fire.|
|Very High||High-intensity fire with partial to full crown involvement. Head fire conditions beyond the ability of ground crews; air attack with retardant required to effectively attack fire's head.|
|Extreme||Fast-spreading, high-intensity crown fire. Very difficult to control. Suppression actions limited to flanks, with only indirect actions possible against the fire's head.|
|NIL||No calculations were performed for this region.|
