Heavy snow and ice could wreak havoc across the western United States over the weekend as winter weather advisories and warnings have been issued by National Weather Service.

It’s already been a cold week on the West Coast with two storm systems coming in from the Pacific. They have brought snow, freezing rain and bitter temperatures to the region with forecasters expecting these conditions to continue for the next two days.

Seven states all have different winter weather-related warnings and advisories over the weekend: Alaska, California, Montana, Maine, Nevada, Utah and Wyoming. Some locations are expected to see anywhere between 1 and 3 inches of snow while others are expected to see larger amounts ranging from 8 to 13 inches.

Here’s where those warnings are this weekend.

Alaska

National Weather Service office in Juneau issued a winter storm warning for the Skagway and White Pass areas of the state. Heavy snow with accumulations of up to 9 inches is expected to fall throughout the day on Friday. Wind gusts of up to 35 miles per hour are forecast.

“If you must travel, carry an extra flashlight, food and water with you in case of an emergency,” the weather service said in its warning.

California

Parts of Northern California are under a winter weather advisory, with between 4 and 10 inches of snow expected. The areas under these warnings are Quincy, Chester and Blue Canyon, California.
