    Ongoing snowfall and wind continues to refresh the storm slab problem. This will be most reactive in wind affected terrain in the alpine and open areas of tree line.

  • Forecast snowfall amounts are uncertain.

Avalanche Summary

Natural avalanche activity is expected in steep open terrain Thursday night into Friday.

There has been sporadic natural activity in steep alpine terrain this week, typically during periods of strong wind. Several size 2 avalanches were observed from the steep gullies of Mt McDonald and Tupper on Wednesday. Two size 1.5s were observed near Grizzly couloir on Tuesday.

Snowpack Summary

Another 15-20cms will fall over the ~100cm of snow that has fallen in the last 8 days.

In the alpine and open tree line areas recent snow has been redistributed by strong winds. In sheltered terrain and below tree line the snowpack is well settled and supportive.

There are a couple of crusts in the mid and lower snowpack that have not shown signs of reactivity recently.
