Motorists on the
mountain roads are advised to avoid travel during storm events and to SLOW DOWN! Chains
will be required in mountain areas. Remember to bring chains even if it not
snowing due to sudden weather changes.

Mud and debris flows are always possible during
heavy rain events.
Recent burn areas such as State Route 38 through Forest Falls/Mountain Home
Village (Valley Fire), State Route’s 74 and State Route 243 in Idyllwild and
Mountain Center (Cranston Fire), and State Route 74 and Interstate 15 in
Corona/Lake Elsinore (Holy Fire) are areas of concern.
Evacuations and road closures may be possible on
state and local highways due to debris flows. Desert regions are also
subject to mud and debris flows. Mountain regions typically experience rock
fall activity during and after storm events.
