Firefighters continue to battle multiple blazes in Southern California while President Trump is set to visit Los Angeles to tour wildfire damage.

The blazes - named Laguna, Sepulveda, Gibbel, Gilman and Border 2 - flared up on Thursday in Los Angeles, San Diego, Ventura and Riverside.

Border 2 Fire initially started 2:31 p.m. Jan. 23 in San Diego County. After being active for 20 hours, it has burned 5,389.4 acres, an increase of 1,139 acres since the last update. A fire crew of 692 effectively contained 10% of the fire by Friday noon. The blaze's cause remains under investigation.

Firefighters made progress on the more than 10,000-acre Hughes Fire Friday, which sent thousands fleeing after sparking near the Los Angeles County community of Castaic a day earlier.

Evacuation orders and warnings were issued to more than 31,000 people in the vicinity of two new wildfires north of Los Angeles on Wednesday.

With many parts of Los Angeles County still smoldering from wildfires, the expected rain this weekend would seem like a welcome relief. But how the rain falls could make the difference between a disaster respite or a disaster repeat.

Over 1,100 firefighters were “strategically pre-positioned” across Southern California to address "ongoing critical fire weather," Cal Fire said.
