The next system in a series of powerhouse storms will slam onshore Sunday into Sunday night.

Very heavy snow will impact northern California with another 1-2 feet likely Sunday and Sunday night. This will bring snow totals for this event up to 2-4 feet of snow across Mount Shasta City, Dunsmuir, McCloud and Tennant.

Portions of Interstate 5 near Mount Shasta City and Highway 89 near Snowman's Summit will likely be impassable at times due to the snow later Sunday into Sunday night.

This image, courtesy of the California Department of Transportation, shows the road is snow-packed and dangerous early Sunday morning near Snowman's Summit.

The snow will also have severe impacts east of the Cascades on Highways 140 and 97.

Strong, gusty winds of 40-60 mph will cause blowing and drifting snow, which will significantly limit visibility.

Several inches of snow are also expected in the Coastal Range and Northeast Foothills.

The heavy, wet snow will likely cake on many surfaces, and combined with the wind, power outages will also result.

If you will be traveling through the region, be prepared for the extreme winter weather.

Have food, water, blankets and warm clothes ready in case you get stranded. You should also be sure to carry chains and practice putting them on your vehicle before heading out.

It will be wetter, rather than whiter, for the lower elevations. Areas from Santa Maria north to Santa Cruz, San Francisco and Eureka will see 1-4 inches of rainfall and localized flooding.
