Two major storms are wreaking havoc across the country, possibly spoiling many people's Thanksgiving travel plans.
The National Weather Service says that much of the U.S. is expected to get heavy snow, rain, and powerful winds.
"This is not an ordinary storm," the NWS said.
NWS said a "bomb cyclone" is headed for Northern California and southern edge of Oregon that could include two feet of snow in the mountains and 35-foot waves along the coast.
California shut down Interstate 5 between Yreka and Redding due to blizzard conditions. A flash flood watch is also in effect for parts of southwestern California.
A separate snowstorm also hit Denver on Tuesday, dumping 10 inches of snow at the Denver International Airport. The snowstorm caused the cancellation of more than 450 flights and stranded more than 1,000 passengers.
The storm also left nearly three feet of snow in northern Colorado before moving east toward the Great Lakes area.
The storm is expected to dump six inches of snow in central and southern Minnesota and up to nine to 12 inches in other areas. Western and northern Wisconsin could see up to a foot of snow, with more in areas close to Lake Superior.
Weather officials near Chicago warned that winds may exceed 60 mph.
The storm is expected to arrive on the east coast on Wednesday or Thursday.
