Under a Red Flag Warning, it is crucial to avoid any activities that could spark a fire. This includes refraining from open burning, being cautious when using equipment that produces sparks, and properly disposing of cigarettes. Ensuring that all outdoor flames are completely extinguished is also vital, as is maintaining vehicles to prevent exhaust systems from emitting sparks. The dry conditions mean that vegetation is highly flammable, so homeowners should clear dry leaves and debris around their properties to create a defensible space against approaching fires.
