SACRAMENTO (CBS13/AP) — Heavy rain is drenching much of Northern California and more is on the way.
So much rain has fallen, the National Weather Service has issued an Urban and Small Stream Flood Advisory for parts of the Valley and Sierra foothills.
They advisory is for Sacramento, Roseville, Folsom Elk Grove, Woodland Vacaville, Fairfield, Grass Valley, Auburn, Jackson, San Andreas and areas north of Sacramento.
The weather service says excessive runoff from heavy rains will elevate small creeks, stream and cause ponding on streets and underpasses.
Even heavier rain is expected tonight and motorists should be extra cautious as it becomes more difficult to see water on the roadway.
Showers and possible thunderstorms are expected for Saturday along with colder temperatures.
The Sierra is under a winter storm warning and could see up to 4 feet of additional snow at the highest elevations.
Ski resorts are welcoming the storms touting the best conditions so far this season. Several resorts are hosting special events this weekend including Heavenly’s Winter Snow Blast, Kirkwood’s Freeride Flow Festival and Squaw Valley’s inaugural Snow Bash.
Meanwhile, in the Los Angeles area rain is expected to hit after 11 p.m. and continue through Saturday with a chance of rain on Sunday.
Up to 12 inches of snow was expected in Southern California mountains above 4,000 feet, and even the Santa Monica Mountains rising above the Malibu coast could see a light dusting.
