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

A third winter storm moving across Southern California could make driving through the Grapevine increasingly dangerous, but so far, things haven't been so bad.

The northbound 5 Freeway has faced closures and delays throughout the week due to wintry conditions, and more disruptions are possible Thursday night.

A third winter storm moving across Southern California could make driving through the Grapevine increasingly dangerous, but so far, things haven't been so bad.

We drove down the freeway - just a few miles out of Castaic toward Frazier Park - and there were relatively manageable conditions as the storm approached.

A winter storm warning remains in effect through Friday morning, with up to four inches of snow possible near the pass.

Drivers can expect rain mixed with snow at times, plus gusty winds strong enough that officials are urging those pulling trailers or driving campers to avoid the area.

With temperatures expected to drop below freezing, slush and black ice could make the roadway especially hazardous.

"I'm a Frazier Park resident so I'm a little familiar with the weather conditions," said one driver. "Just take it slow, and if it's too dangerous, don't be on the road."

Some drivers traveling near Frazier Park watched snow gather on the surrounding mountains, wondering whether the snowline might drop and force another freeway closure.

"They sometimes close the 5 freeway when it snows or when you know it freezes," another driver said.

Caltrans has advised travelers to check conditions before heading out and to prepare for possible closures or chain requirements as the storm continues.

A powerful burst of rain and wind swept through the Inland Empire on Thursday, creating dangerous driving conditions in the Cajon Pass and surrounding mountain communities.

Temperatures hovered around 37 degrees Thursday morning and wind gusts remained strong.

Video captured earlier in the day showed heavy traffic along the 15 Freeway even before the rain arrived.

A semitruck slid off the road, prompting Caltrans crews and emergency workers to pull it back onto the freeway. Though the crash was not weatherrelated, it contributed to slowdowns that worsened once the storm moved in around 9 to 10 a.m.

Winddriven rain reduced visibility, blowing horizontally across the freeway. Several drivers from out of the area said the conditions required extra caution.

"Slow down. Give some space," one driver said. Another added, "It's difficult with all the rain. We come from a rural area, so we're not used to this, but if I pay attention, I do okay."

In Lake Arrowhead, there was snow in lower elevations. Strong winds in the mountains toppled a large tree onto a home, leaving it uninhabitable.

Forecasts indicated the storm would move out quickly.

The third storm of the week is quickly moving into Southern California, bringing more rain and snow, but the region will soon get a break from the wet weather.

Light to moderate rail will continue to move east, with heavy downpours possible at times. Cold temperatures and gusty conditions with potentially damaging winds will remain even after the rain stops.

The widespread rain will begin to taper off by the early afternoon hours as it moves into the Inland Empire.

Southern California's mountain resorts are welcoming all the fresh snow that's been dumped by recent winter storms.

In Wrightwood, Mountain High Resort has received more than 28 inches of fresh snow over the past seven days. The resort says up to another 11 inches are expected to fall Thursday.

Southern California's mountain resorts are welcoming all the fresh snow that's been dumped by recent winter storms.

Nearly all of the west resort is open, including five new trails.

"These are killer conditions for Southern California. You can't complain," said skier Nav. "...This is prime time... We're really excited and really fortunate to have the weather."

Chair lifts are expected to be running later today as the resort makes even more snow on site.

Expect cold and gusty conditions with a high around 34 degrees.
