Understanding Fire Danger

Lincoln County FireSafe Council

Low Fire Danger


Fuels do not ignite readily from small firebrands although a more intense heat source, such as lighting, may start fires in duff or punky (dead& rotting) wood. Weather and fuel conditions will lead to slow fire spread, low intensity and relatively easy control with light mop-up. There is little danger of spotting. Controlled burns can usually be executed with reasonable safety.
Low Fire Danger


Fires can start from most accidental causes, but with the exception of lightning fires in some areas, the number of starts is generally low. Expect moderate flame length and rate of spread. Short- distance spotting may occur, but is not persistent. Fires are not likely to become serious and control is relatively easy. Although controlled burning can be done without creating a hazard, caution should be taken.
High Fire Danger


All fine dead fuels ignite readily and fires start easily from most causes. Unattended brush and camp fires are likely to escape. Fires spread rapidly and short-distance spotting is common. Fires may become serious and their control difficult unless they are attacked successfully while small. If outdoor burning is allowed it should be restricted to early morning and late evening hours.
Very High Fire Danger

Very High

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 in heavier fuels. Both suppression and mop-up will require an extended and very thorough effort. Outdoor burning is generally not allowed. Fire Restrictions may be in effect.
Extreme Fire Danger


Fires start quickly, spread furiously, and burn intensely. All fires are potentially serious. Development into high intensity burning will usually be faster and occur from smaller fires than in the very high fire danger class. Every fire start has the potential to become large. Expect extreme, erratic behavior. NO OUTDOOR BURNING ALLOWED. Fire Restrictions are generally in effect.
Red Flag Warning

Red Flag Warning

A short term, temporary warning indicating the presence of dangerous combinations of temperature, wind, relative humidity, fuel or drought conditions which can contribute to new fires or rapid spread of existing fires. Can be issued at any Fire Danger level.
