Instruction: 
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. Follow all fire restrictions. One less spark, one less wildfire.
