The National Weather Service said accumulating snow, strong winds and significant blowing and drifting snow are the main concerns.
Dangerously cold wind chills as low as -20 degrees are settling in early Thursday. The NWS said those conditions will cause frostbite on exposed skin in as little as 30 minutes and anyone outdoors risks hypothermia.
The NWS advises avoiding outdoor activities when possible. If you have to be outside, appropriate winter clothing including hats and gloves are a must.
The Wasatch Back could see up to 7 inches of snow by the time the storm moves out later Thursday.
If you are traveling during the storm, you can check live road conditions and emergency alerts from the Utah Department of Transportation.
