LOS ANGELES, CA – It’s starting to look a lot like a White Christmas in the mountains around Los Angeles as the city’s freeways will be slick with rain as people head to Christmas Eve and Christmas Day gatherings. Christmas
A powerful atmospheric river-fed storm system is making its way through Southland on Thursday, raising fears of possible flooding or debris flows in some recently scorched areas. As well as wet roads, the temperatures will be cooler, perfect for sipping hot chocolate by the fire and watching holiday movies.
National Weather Service forecasters said some mountainous areas could receive 3 to 6 inches of “atmospheric river” rain, with the heaviest showers expected after midnight through Friday morning.
Rain will persist intermittently — possibly heavy at times — throughout the holiday weekend, according to the National Weather Service.
“Unstable weather will prevail across the region with periods of rain through Sunday morning, the heaviest Thursday through early Friday,” according to the weather service.
“Snow levels will remain quite high (Wednesday) and Thursday, but will drop significantly from Friday evening through Saturday. Temperatures will be significantly below normal across the region.”
Snow levels will initially be around 9,000 feet but will drop below 8,000 by Friday afternoon, bringing light snow to around 5,000 feet from Friday evening through Saturday morning.
The forecast comes with the usual travel warnings.
“Moderate rain could create slippery roads and travel delays, as well as high mountain snow accumulations and gusty winds,” forecasters said. “Additional rain and lower snow levels could impact travel this holiday weekend.”
Daytime temperatures are expected to be in the upper 50s to mid-60s on Thursday, in the high 50s to lower 60s on Friday, and in the high 50s to around 60 on Christmas Day.
Angeles National Forest tweeted Wednesday that due to upcoming rains and low snow levels, the following roads have been closed:
3N17 from BD to Mill Creek;
4N37 Indian Canyon passable in 4×4 only;
4N24 Bear Trap;
