Today's Fire Danger

Using current conditions and weather patterns over the last 52 days
Fire danger is calculated at Solar Noon each day
Forecast is for time of highest risk, usually mid-late afternoon

MODERATE FIRE DANGER IS FORECAST
Fires can start from most accidental causes but, with the exception of lightning fires in some areas, the number of starts is generally low. 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. Short-distance spotting may occur, but is not persistent. Fires are not likely to become serious and control is relatively easy.

Based on current temperature and humidity


CURRENT FIRE RISK IS LOW

Fuels do not ignite readily from small firebrands although a more intense heat source, such as lightning, may start fires in duff or punky wood. 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. There is little danger of spotting.
