HIGH FIRE DANGER IS FORECAST All fine dead fuels ignite readily and fires start easily from most causes. Unattended brush and campfires are likely to escape. Fires spread rapidly and short-distance spotting is common. High-intensity burning may develop on slopes or in concentrations of fine fuels. Fires may become serious and their control difficult unless they are attacked successfully while small. FIRE BEHAVIOUR: Fire Weather Index ... HIGH (20) Initial Spread .......... LOW (4) Build Up Index ........ EXTREME (277) FUELS MOISTURE: Fine Fuel Moisture .. HIGH (89) Duff Moisture ......... EXTREME (213) Drought ................ EXTREME (997) |

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.
