Luckily the Sesnon or Porter Ranch fire was not caused by arson. They investigated and determined that the cause was electric power lines.
In our high winds, power lines are often the cause of brush fires and wildfires that get completely out of control.
All evacuations have been lifed for both Los Angeles fires, Sesnon and Marek. That means that no homes are in danger at this time. Let's hope it stays that way.
