It isn't just British Columbia's outback that is prone to avalanche danger this weekend, two major routes through the province have been closed because of the avalanche threat.

Highway 1 has been shut down in three locations between Craigellachie and Golden, B.C., either because of the high avalanche hazard or for avalanche control.

Highway 3 on the west side of Kootenay Pass has also been closed because of the high avalanche hazard.

The Canadian Avalanche Centre has listed the danger rating in the North and South Columbia regions and the Kootenay Boundary area as high, meaning conditions are very dangerous and travel in the back country is not recommended.

The centre says strong westerly winds along with a series of approaching storms in the area will establish very touchy conditions in the alpine and at the tree line.

In the Kootenay Boundary area, the avalanche centre warns that several buried weak layers of snow exist in the snowpack and the oncoming storms could trigger deep and heavy avalanches.
