    Touchy storm slabs continue to build with deeper slabs on leeward slopes due to wind loading. Widespread natural avalanches are likely.

Avalanche Summary

On Tuesday, explosive control and natural avalanches were reported up to size 2.
On Monday, a natural avalanche cycle up to size 3 was reported.
With more snow and strong forecast winds, you can expect this to be the story on Wednesday.

Snowpack Summary

Heavy snowfall continues to add to the upper snowpack with up 120 cm of recent storm snow in the alpine. Strong southwest winds have loaded leeward slopes and potentially scoured windward slopes down to an old melt-freeze crust.

Buried surface hoar crystals may linger in isolated sheltered areas.

The mid and lower snowpack is expected to be strong, with frozen crusts or dense, settled snow.

At treeline around Terrace we expect a snow depth of 200-250 cm. 250-350 cm around Stewart. Snowpack depth gradually thins as elevation decreases.
