Fire Danger Key

LOW

• Fires do not readily start.
• Fires that do start spread slowly with low resistance to control.

MODERATE

• Fires can start from most accidental causes, but the number of starts is generally low.
• Fires burn at moderate intensities, heavy fuel concentrations will burn hot.

HIGH

• Fires start easily from most causes.
• Control of fires can become difficult if initial attack not initiated promptly, especially in heavy fuels.
• Most fires controlled within first burning period.

VERY HIGH

• Fires start readily and spread quickly.
• Resistance to control is high, as is the potential for large fires.
• Fire behavior is often erratic,"blow up"potential is high.

EXTREME

• Severe fire conditions, potential for fire disaster is high.
• Direct attack of fires is virtually impossible, fires often escape initial attack.
• Fire behavior is erratic, "blow ups" may be expected.
• Resistance to control is high, fires not usually controlled until burning subsides.
