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.
