Weather Forecast
Light accumulations are expected till tomorrow morning with South West and North West moderate winds. The Western part of the region will see most of these precipitations. Sunny periods are still expected for Friday with seasonal temperatures throughout the period (-8 C) and light winds from the North West. The upper trough arriving on Saturday should bring light to moderate precipitations on the regions, again, with Westerly upslope seeing most of it. Winds should also pick up to reach moderate to strong speeds from the South West. Another system is following for Sunday, its timing and intensity remains to see.
Avalanche Summary
No new avalanches were reported for this region. Due to our limited observations for this region at this time, your avalanche observations are welcome at forecaster@avalanche.ca
Snowpack Summary
Windslabs should grow slightly tonight in specific areas (Easterly aspects) in the alpine and at treeline with the forecasted light precipitations, moderate winds and the older snow available for transport. The new snow is also burying some older slightly deeper windslabs in sheltered areas. Overall, the top and mid-snowpack is reported to be settling well. The deep persistent instabilities (surface hoar and early November crust) located in the middle and near the bottom of the snowpack are still a concern in this region, however, it is important to know that we have very limited observations for this region at this time. Digging down and making your own observations will be critical to safe slope selection. Any observations from the field are welcome at forecaster@avalanche.ca.Â
