Almost half of the country is bracing for a massive winter storm that has put almost 11 million people from California to Wisconsin into winter weather advisories.
The storm, which already dumped nearly 4 feet of snow across the Sierra Nevada, is expected to bring snow and severe weather into the Rockies and the northern Plains on Monday.
The National Weather Service updated projections on the storm Monday, saying that up to a foot could hit the Rockies, but winds could also top out at around 50 mph.
“This developing storm system will lead to numerous, widespread, and impactful weather hazards in the heart of the country this week,” the National Weather Service said.
Blizzard warnings have been put in place for eastern Wyoming, western Nebraska, and northwest Kansas.
As much as 2 feet could fall across the midwest, including much of southwest South Dakota and parts of Nebraska. But it won’t just be snow because as conditions deteriorate, ice will be among the mix.
By Wednesday, the storm system is expected to hit the Great Lakes, with rain falling in the Ohio Valley before pushing to the Northeast by Friday.
In the south, severe weather is possible through Thursday, according to the National Weather Service. This includes tornadoes risks for 8 million people from Texas to Alabama and as far north as Little Rock, Arkansas.
The storm is called an atmospheric river event, where a column of condensed moisture brings large amounts of rain and snow as it makes landfall, the National Oceanic and Atmospheric Administration shared.
