Wildfire Danger Levels
Fires start easily from most causes. Control of fires can become difficult if not attacked promptly, especially in heavy fuels. Most fires can be controlled within the first day of burning.
IGNITION: All fine dead fuels ignite readily and fires start easily from most causes. Unattended brush and campfires are likely to escape.
SPREAD: Fires spread rapidly. High-intensity burning may develop on slopes or in concentrations of fine fuels.
MODERATE = YELLOW
Fires can start from most accidental causes, but the number of starts is generally low. Fires burn at moderate intensities. Fires will burn actively; heavy fuels will burn hot.
IGNITION: Fires can start from most accidental causes, but with the exception of lightning fires in some areas, the number of starts is generally low.
SPREAD: Fires in open cured grasslands will burn briskly and spread rapidly on windy days. Timber fires spread slowly to moderately fast. The average fire is of moderate intensity, although heavy concentrations of fuel, especially draped fuel, may burn hot.
LOW = GREEN
Fires do not readily start. Fires that do start, spread slowly and usually are easy to control.
IGNITION: Fuels do not ignite from small firebrands although a more intense heat source, such as lightning, may start fires in duff or dry rotted wood.
SPREAD: Fires in open cured grasslands may burn freely a few hours after rain, but woods fires spread slowly by creeping or smoldering, and burn in irregular fingers
