Nearly an entire month's worth of snow could fall across some parts of California over a four-day period beginning this weekend.
Winter weather advisories and winter storm warnings were issued across parts of the country on Monday amid heavy snow.
Forecast models show up to 10 feet of snow and 80 MPH winds hitting in a powerful multi-storm pattern.
The warnings come ahead of a "significant" snow event accompanying a winter storm set to hit the U.S. this weekend.
