Multiple brush fires erupted in San Diego’s North County early Tuesday morning, prompting a fast response from firefighters and mandatory evacuations.

A brush fire that started overnight in the Bonsall area prompted evacuations as it threatened structures in the same area where a 2017 wildfire burned down more than a hundred homes.

"The fire is growing with a moderate rate of spread and structures are threatened," Cal Fire said as it issued evacuation orders.

The Lilac Fire, one of three brush fires that broke out in San Diego County overnight, has already displaced 86 residents and damaged two structures.

Two brush fires burning along I-15 in northern San Diego County have prompted evacuation orders for some as they burn at high rates of speed due to strong winds in the area.
