What caused the sylmar fire?

The Sylmar Fire, which occurred in 1985 in Los Angeles, was primarily caused by a combination of strong winds and dry conditions that contributed to the spread of flames. It was ignited by a downed power line during Santa Ana winds, which are notorious for their ability to rapidly carry fire through vegetation. The fire ultimately burned over 1,000 acres and destroyed numerous homes, highlighting the risks associated with wildfires in the region.
