Fire Behavior is Affected by Weather, Fuel and Terrain

Weather — is the biggest variable, with the most serious impact and least control, but can be forecast

Natural Fuels — we can reduce this danger

Terrain Features — we can minimize risk to wildfire

Embers and Wind — we can protect ourselves from this most dangerous fire behavior

  • 60% of house fires are started by embers
  • Embers can travel up to 6 miles from the flame front
  • Embers can sit on a roof for up to 4 hours
  • Fire moves up hill at 2 – 6 mph with no wind
