A Red Flag Warning is issued when we identify weather conditions that promote rapid spread of fire which may become life-threatening. This does not mean there is a fire. These conditions are either occurring now or will begin soon. It is important to have multiple ways to receive information from authorities. Please advise the appropriate officials or fire crews in the field of this Red Flag Warning.
