A Red Flag Warning remained active for inland and mountain communities through Friday morning, which means it could be another busy day for local fire crews.

The Hughes, Sepulveda and Laguna fires are among the latest blazes for Southern California during a fourth consecutive day of red flag fire weather warnings.

High fire danger warnings have been a recurring theme for Los Angeles in January. Here's a look at how many red flag warnings were issued this month.

A critical fire threat will continue across County as Santa Ana winds and dry conditions persist through early Friday, according to the National Weather Service.

"If fire ignition occurs, conditions are favorable for very rapid fire spread and extreme fire behavior," the NWS warns.

Another round of Santa Ana winds in the forecast led to the extension of a Red Flag Warning for parts of San Diego County.

Another blast of Santa Ana winds Thursday prompted San Diego Gas & Electric to cut off electricity to thousands of residents in another of a wave of power outages that have continued off and on for two weeks.

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

The bushfire started northwest of Downtown Los Angeles and spread from Los Angeles County to Ventura County and prompted evacuations.
