(LOS ANGELES) -- Less than a week after a massive wildfire shut down California's Interstate 5, a major freeway between Los Angeles and the San Joaquin Valley, the traffic artery was closed again due to heavy snow, authorities said.
Both the southbound and northbound lanes of Interstate 5 remained closed Monday morning and the California Highway Patrol said there is no timeline on when it will be reopened.
A CHP spokesperson told ABC News heavy snow caused the closure of I-5 from Castiac, near where the Hughes Fire shut down the freeway on Wednesday. The stretch of I-5 is also known as "The Grapevine."
The area, as well as other mountainous areas north of Los Angeles, was forecast to get six inches to a foot of snow.
The Hughes Fire, one of a series of major blazes that have devastated the Los Angeles metro region since Jan. 7, erupted on Wednesday near Castaic Lake reservoir, about 45 miles north of downtown Los Angeles. The fire, fanned by strong Santa Ana winds, grew quickly to more than 10,000 acres, prompting the mandatory evacuation of about 30,000 residents and putting another 20,000 on an evacuation watch.
More than 4,000 firefighters responded to the blaze, attacking it from the ground and air and preventing it from damaging any homes, officials said.
The Hughes Fire is one of four active fires still burning across Southern California, according to the California Department of Forestry and Fire Protection. The Hughes fire was 95% contained on Monday morning, according to Cal Fire.
A weekend storm brought much-needed rain to Southern California. But the first significant rain in the area since June 1 was also accompanied by threats of a different natural disaster. Overnight, a flash flood warning was issued by the National Weather Service for Malibu, where homes and businesses were destroyed by the Palisades Fire, the largest of the blazes to devastate Los Angeles County this month.
Pacific Coast Highway west of Topanga Canyon Boulevard in Los Angeles County was closed around 4:30 p.m. Sunday due to mudflows, officials said. Mudflows in the burn-scarred areas of fire-ravaged Pacific Palisades also caused the shutdown of several main roads in the area, including the northbound lanes of Sunset Boulevard, officials said.
As of Monday morning, parts of Los Angeles County had received 1.2 inches of rain. Downtown Los Angeles had gotten nearly a half-inch of rain and Santa Monica received almost an inch. Meanwhile, Santa Barbara County got 1.75 inches of rain and Ventura County, south of Los Angeles, had received 1.36 inches.
An additional half an inch of rain is possible for parts of Southern California through Tuesday.
The rain was a welcomed sight to firefighters still battling active blazes in the region, including the Hughes Fire.
The Palisades Fire, which started on Jan. 7 and exploded to over 23,000 acres, was 94% contained on Monday. The fire destroyed nearly 7,000 structures, including homes and businesses, and killed 11 people.
The Eaton Fire, which also broke out on Jan. 7 in Pasadena and Altadena, was 98% contained on Monday. The Eaton Fire burned more than 14,000 acres, destroyed more than 9,400 structures, including homes and businesses, and was blamed for the deaths of 17 people.
The fourth active Southern California fire was the Border 2 Fire south of San Diego near the Mexico border. The blaze, which started Thursday afternoon, was 43% contained on Monday after burning more than 6,600 acres of wildland.
"Rainfall overnight and into the morning hours has led to a substantial decrease in fire activity," Cal Fire said in an update Monday morning. "While not ending the possibility of fires in the long term, the saturation of grass and other light, flashy fuels will lessen the threat of the spread of the Border 2 Fire."
