Great Basin Coordination Center
Fuels and Fire Behavior Advisory
Updated July 14, 2017
The Great Basin Coordination Center has released a fuels and fire behavior advisory for Central and Northern Nevada, Northern and Western Utah, and
Southern Idaho.
Extraordinary fine fuel loading and very low fuel moisture is contributing to extreme fire behavior and high resistance to control across Central and Northern Nevada, Northern and Western Utah and Southern Idaho.
Fine fuel loadings are 200-300% above average across much of the advisory area. Very hot and dry conditions over the last few weeks have caused live
and dead fuel moisture to rapidly decrease to critical levels. Lightning will increase across Nevada, Utah and Idaho through early next week with the continued pulses of monsoon moisture around the periphery of high pressure bringing drier lightning to these areas. The likelihood of new fire starts
showing rapid growth and extreme fire behavior is high.
Concerns to Firefighters and the Public:
• Anticipate rapid rates-of-spread, even in the absence of slope and wind.
• Anticipate flashy fine fuels and pinyon-juniper to ignite easily and exhibit advanced rates of spread, elongated flaming fronts and increasing fire brands; expect more long range spotting.
• Anticipate dust devils and fire whirls to develop in hot, dry and unstable conditions, especially in fine flashy fuels, that may jeopardize control lines and contribute to erratic fire behavior.
• Anticipate large areas to be consumed in a short time periods, even in low slope and low wind conditions.
• Expect longer burn periods at mid to higher elevations.
• Fine fuel loadings are dense and continuous and will support extreme rates of spread regardless of fuel heights.
• Thunderstorms may produce strong outflow winds that may rapidly increase fire behavior and change spread direction.
• Fire behavior will burn the fine flashy fuels leaving some shrub components or perennials until the live fuel moisture values drop below critical levels. Watch out for re-burn situations even in grass fuels!
