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.

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

Scores of residents were urged to flee as fast-moving fires hurtled through bone-dry brush in Bonsall and Mission Valley Tuesday

A wind-driven wildfire charred dozens of acres in the sparsely developed northeastern reaches of San Diego County, damaging structures and forcing pre-dawn evacuations before crews could gain the upper hand on the flames Wednesday.

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