Keep that umbrella handy, Southern California. An impactful winter storm is expected to bring heavy rain, snow, and gusty winds to our county next week. Here’s what we’re tracking so far.

Rain will return to our region via multiple weather systems that “will be wetter than our last storm,” and cold enough to produce snow for some local mountain communities, according to NBC Los Angeles meteorologist David Biggar.

As of Friday, Feb. 13, no weather watches or warnings were in effect in connection with the upcoming storm, but that could change over the weekend.

Sunday, Feb. 15

It will be mostly cloudy with chances of drizzle increasing throughout the day.

Monday, Feb. 16

Starting in the morning, the heaviest rain is expected to move across the region from west to east, Biggar said.

Thunderstorms are possible, as well as strong winds. Snow could come down at higher elevations around 6,000 feet.

Tuesday, Feb. 17

Rain is expected to continue, but it won’t be as intense as Monday’s rainfall. Snow levels will drop to 4,000-5,000 feet and lower overnight, including at the Grapevine, which may see a dusting of snow as low as the Cajon Pass and parts of Antelope Valley. Drive carefully.

On and off showers will linger into Wednesday, and low snow is possible at 2,500 feet.

“Each system will be colder than the previous one, which will drop snow levels, but also decrease the amount of rain that could fall,” Biggar explained.

As snow levels drop on Tuesday, Feb. 17 and Wednesday, Feb. 18, drivers should take precautions on mountain roadways and through the passes.

The storm could cause flooding along some roadways. Rockslides and debris flows are possible through steep terrain or along canyon roads.

Wednesday, Feb. 18

As of now, 1-3 inches of rain could fall in most areas through Wednesday. The foothills and mountains could see 2-4 inches of rain, Biggar said. Mountain areas above 6,000 feet could see between 1-2 feet of snow through Wednesday, Feb. 18.

Thursday, Feb. 19

The forecast for Thursday is still up in the air, but another round of showers is possible, Biggar said.
