Hughes Fire in LA County explodes to over 5,000 acres in just 2 hours, with evacuations near Castaic

With high winds driving the flames, a fast-moving wildfire exploded to more than 5,000 acres near the Los Angeles County community of Castaic Wednesday — prompting mandatory evacuations and road closures as it continued to spread.

The Hughes Fire broke out near Castaic Lake, off Lake Hughes Road just north of Castaic Reservoir Road, before growing to 500 acres within an hour. By 12:30 p.m., less than two hours after it was first reported by fire officials, it had ripped through 3,407 acres, according to the California Department of Forestry and Fire Protection, or Cal Fire.

About half an hour later, at 1:03 p.m., it was estimated to be 5,054 acres with 0% containment, Cal Fire said.

All lanes of the northbound I-5 Freeway were being shut down just north of SR-126, the California Department of Transportation, or Caltrans, announced just before 2 p.m. The detour for drivers is SR-126 with an alternate route of SR-14, authorities said.

The unincorporated community of Castaic is located in northwest Los Angeles County, about 15 miles northwest of the city of Santa Clarita and just alongside the Angeles National Forest. The Santa Clarita Valley is home to Six Flags Magic Mountain, where a huge plume of smoke from the Hughes Fire was visible in the nearby area.

Mandatory evacuation orders were expanded as the wildfire spread to over 5,000 acres in just around two hours, sending people fleeing from the area as heavy traffic built up along some roads. Authorities were trying to keep people calm as the situation quickly unfolded — a changing series of new updates and evacuations being announced just as they were earlier this month.

On Jan. 7, two major wildfires sparked on opposite sides of Los Angeles County, killing at least 28 people as they tore through tens of thousands of acres and burned down entire communities, including homes, schools, churches and grocery stores throughout the especially hard-hit areas of Altadena and Pacific Palisades. 

“We’re just asking people to- I know it’s hard to say, but stay calm and just listen to first responders,” California Highway Patrol Officer Isabel Diaz said Wednesday afternoon, as the Hughes Fire continued to spread. “It’s a very active and chaotic scene at the moment, and we’re just all trying our best to get everyone out safely.”

When the flames first broke out, that area of Los Angeles County — including the Santa Clarita Valley — was under a Red Flag Warning, with extremely low humidity and Santa Ana winds increasing the risks of wildfires starting and quickly growing. 

“It does have a high potential for spread because we are looking at 32-mph winds as we speak,” LA County Fire Department Captain Sheila Kelliher Berkoh said. “Those winds are supposed to pick up as the afternoon progresses into the evening.”  

With an especially dry winter in Southern California, experts have said vegetation in the region is particularly dry, and therefore, even more flammable than usual. In California, wildfires during the fall and winter months can be especially dangerous due to shrubbery being dried out through in the summer — which can spark and fuel the fires — along with the seasonal dry Santa Ana winds that can fan the flames forward.

“This time of year is especially dangerous,” said Fred Fielding, spokesman for the LA County Fire Department. “It’s been almost 300 days since we’ve had any significant rainfall.”

Currently, Angeles National Forest — where the Hughes Fire broke out — is closed to the general public for the protection of natural resources and public safety. The closure runs from Jan. 19 through Friday, Jan. 24.
