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

Forward progress was stopped on the Lilac fire around 10 a.m. It was one of three fires in North County early Tuesday.

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.

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.

The fires come as San Diego County mountains and valleys, along with other parts of Southern California, remain under a red flag warning.
