California sees rare tornado risk on Monday

Flooding isn’t the only concern as this latest atmospheric river storm slams California.
There’s now a threat of severe weather, including possible tornadoes, in portions of Central and Northern California on Monday. Other threats from thunderstorms that develop include damaging wind gusts.
NOAA’s Storm Prediction Center has placed parts of California’s Sacramento Valley region under a Level 2 out of 5 on its severe thunderstorm risk scale.
The Level 2 risk includes Sacramento, Stockton and Modesto.

The FOX Forecast Center said that computer forecast models seem to be hinting at more clearing and breaks in the clouds later in the day on Monday. That will allow for more instability in the atmosphere, leading to a setup that favors the organization of strong to severe thunderstorms.
The tornado risk runs from north of Chico through Sacramento and Stockton and into Modesto. The eastern shores of San Francisco Bay are also under the low risk of tornadoes on Monday.
HOW YOU SHOULD PREPARE FOR A TORNADO
Winds will be whipping in California

Damaging wind gusts are also possible as the atmospheric river storm slams into California early this week.
"(The winds) are going to be pretty gusty and strong," FOX weather Meteorologist Craig Herrera said. "That could bring trees down."
Power outages are also possible due to the possibility that trees could be brought down due to the higher wind gusts.
"Be ready for some of these old trees, old oak trees and eucalyptus trees," Herrera continued. "Those eucalyptus trees don’t have a good root system, so those could come down pretty quickly."
WHAT YOU SHOULD KNOW ABOUT HIGH WIND WARNINGS

Sierra Nevada to be slammed with snow

Snow is expected in the higher elevations of the Sierra Nevada mountain range – and a lot of it.
"I mean, we’re talking about 1 to as much as maybe 3 feet of snow, especially in the higher elevations," FOX Weather Meteorologist Kendall Smith said.
The snow could lead to some treacherous travel at times, and travel itself could be nearly impossible on untreated roads and highways in the area.
The snow totals will increase the higher you go in elevation.
