are either occurring now....or will shortly. A combination of
strong winds...low relative humidity...and warm temperatures can
contribute to extreme fire behavior. PDS Red Flag conditions are
extremely rare due to a combination of high winds and very dry
fuels. New fires will grow rapidly and out of control. Residents
should be prepared to evacuate if a wildfire breaks out. Have
multiple ways to receive instructions from emergency managers,
and evacuate if ordered to or if a fire threatens.
