Lightning strikes may occur outside of main precipitation cores. Gusty and erratic outflow winds could occur near any thunderstorm development.
A Red Flag Warning indicates that critical fire weather conditions are either occurring or will shortly. Lightning may create new fire starts and could combine with strong outflow winds to cause a fire to rapidly grow in size and intensity.
