Average Flame Length shows the average length of flames expected, given local fuel and weather conditions. Flame lengths have potential to exceed the mapped values shown, even under normal weather conditions. Flame length is commonly used as a direct visual indication of fire intensity and is a primary factor to consider for firefighter safety and for gauging potential impacts to resources and assets. It can also guide mitigation work to reduce the potential for catastrophic fires by showing where work can be done to reduce higher potential flame lengths/fire intensities to lower flame lengths/fire intensities. Be aware that conditions vary widely with local topography, fuels, and weather, especially local winds. In all areas, under warm, dry, windy, and drought conditions, expect higher likelihood of fire starts, higher flame lengths/fire intensities, more ember activity, a wildfire more difficult to control, and more severe fire effects and impacts. Nonburnable: In this area there are a majority of non-burnable fuel types such as water, urban, agriculture, barren rock, glacial areas, etc. 4 Feet: Under normal weather conditions, a fire in this area can be expected to be low intensity. The fire may exhibit on average, 4 foot flames, and is expected to be low to moderately difficult to control. 4-8 feet: Under normal weather conditions, a fire in these areas can be expected to be moderate intensity. The fire may exhibit on average, 4-8 foot flames, and is expected to be moderately to highly difficult to control. Fires are too intense to work at the front of the flame. Embers travel moderate distances. 8-12 feet: Under normal weather conditions, a fire in these areas can be expected to be high intensity. The fire may exhibit on average, 8-11 foot flames, and is expected to be highly to extremely difficult to control. Expect tree torching and spotting (additional fires igniting away from the main fire). Ember travel increased. Over 12 feet: Under normal weather conditions, a fire in these areas can be expected to b |
