#OCFA is on scene of a fire with a moderate ROS near Silverado Canyon and East Santiago Canyon. Didn't quite hear a size. It is wind-driven. Hoping for a closer cam image.

This is the #SilveradoFire.
Command post will be at the Irvine Lake. The fire about 10 acres with a rapid ROS. Potential for extended attack. No values at risk.
