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

VERY HIGH FIRE DANGER IS FORECAST
Fires start easily from all causes and, immediately after ignition, spread rapidly and increase quickly in intensity. Spot fires are a constant danger. Fires burning in light fuels may quickly develop high intensity characteristics such as long-distance spotting and fire whirlwinds when they burn into heavier fuels.

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.
