Two new fires ignited in San Diego County on Tuesday, as firefighters continue fighting blazes further north in Los Angeles.

The North County Fire Protection District said a total of 86 residents have been displaced by the evacuation orders and at least two structures have been damaged.

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

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

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

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.

Red flag warnings are in effect until Thursday for parts of Los Angeles, Ventura, San Diego, due to low humidity and an uptick in Santa Ana winds.

The Palisades and Eaton wildfires also continue burning in the Los Angeles area, leaving parts of Southern California with devastating fire damage.

LA County Sheriff says about 31,000 people were under mandatory evacuation orders while another 23,000 were under evacuation warnings.

As wildfires continued to burn in Los Angeles, three fires broke out in San Diego County, prompting evacuation orders and warnings.

Continued strong winds and dry conditions on Wednesday morning rapidly spread a fire near Castaic Lake in northern Los Angeles County and has burned through 8,096 acres.

Six wildfires are burning in Southern California, according to the California Department of Forestry and Fire Protection (Cal Fire).
