A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures and exceptionally dry fuels will create dangerous wildland fire conditions. Campfires, outdoor grills, smoking materials, fireworks, chain saws, and all-terrain vehicles all have the potential to throw a spark and ignite a dangerous and destructive fire. Please advise the appropriate officials or fire crews in the field of this Red Flag Warning.
