Live updates: Storm brings flooding, stalled cars near Burbank airport

The California Highway Patrol is warning drivers that up to 3 inches of snow could fall on the Grapevine as a cold winter storm moves into the region, creating potentially dangerous travel conditions.

Traffic on Interstate 5 through the Grapevine remained smooth Tuesday, but officers urged drivers to stay alert.

Authorities are warning drivers that up to 3 inches of snow could fall on the Grapevine as a storm moves into the region, creating potentially dangerous travel conditions.

"Once we start getting significant amount of snow on the roadway, obviously it becomes a little bit more dangerous as far as stopping distances and speed. We do get a significant amount of crashes increasing in the area," CHP Officer Carlos Burgos Lopez said.

Officials said snowfall could force a shutdown of the Grapevine or require officers to escort drivers.

A fresh layer of snow covered the hills above Lebec, and snow levels were expected to fall to 3,000 feet overnight, raising concerns about rapidly worsening conditions.

In addition to snow, light rain and dropping temperatures could create black ice.

Caltrans crews plan to monitor the storm and clear roads as conditions allow.

In Woodland Hills, the storm is believed to have caused a massive tree to topple, causing some serious damage to a car and part of a house. It also pulled down some power lines, leaving the neighborhood without power.

"It's just crazy that it came right down on this car where there's other spaces where it could have fell," neighbor Haiyan Heydari said.

After a winter with little snowfall, communities in the San Bernardino Mountains saw conditions shift as a storm on Monday delivered measurable snow -- with more expected later in the week.

According to Big Bear Mountain Resort, the area is forecasted to get 30 inches of snow this week alone. The storms should clear out by the end of the week, making for a great ski weekend.

Winter storm warnings and alerts remain in effect across the region.

Transportation officials urged caution for anyone planning a mountain trip.

"Chain control is in effect, and these chain requirements levels change. We expect some more weather conditions this week," said Jennifer Ceron with Caltrans District 8.

Caltrans advised drivers to check road and traffic conditions through its QuickMap app before heading into the mountain communities.

The city of Los Angeles extended the current evacuation warnings for those living near the Palisades, Hurst and Sunset burn areas.

The warnings will remain in place "until further notice," the city said.

This comes as more rain is expected in the next coming days.
