The Los Angeles County Emergency Operations Center issued a safety statement Sunday for people returning to their homes after the Woolsey Fire.
Fire officials warn residents using Malibu Canyon road to be aware of falling debris including falling rocks because fire fighting activities may have dislodged rocks and made the soil unstable.
Post fire areas adjacent to mountains and hills are known for their ability to produce rock and debris flows. Officials warn residents these flows can form very quickly.
Additionally, areas not prone to flooding may now be at larger risk because of higher than normal flows from streams and rivers.
In preparation of the upcoming rain events, officials in Los Angeles and Ventura counties have transitioned into emergency response organizations with an emphasis on debris, flood fighting and support activities.
Those activities include pre-planned routines such as the monitoring of all flood facilities and equipment, the operation of debris dams and the provision of logistics support, field operations and responses to emergency situations.
Sandbags and sand will be made available to all residents at Los Angeles County and Ventura County fire stations.
As aircraft operations continue in the area of the fire, the public is reminded never to fly unmanned aircraft systems (drones) near wildfires.
Due to the potential for collision when a drone is detected flying over or near a fire area, air operations must be suspended until all drones flying in the wildfire area are removed.
A temporary flight restriction is in place in areas impacted by the fire until Jan. 15, 2019.
