    Recent moderate SW winds has redistributed the storm snow creating pockets of windslab that could be reactive to skier triggering.

    Deeply buried weak layers of facetted crystals continue to be a concern on slopes with a shallow snowpack especially in the Northern part of the region.

Weather Forecast

Tonight and Sunday:  A weak disturbance is forecasted to bring mainly cloudy skies, a possibility of light precipitation with light N-NE winds, freezing levels at 500 m. and alpine temperatures around -10 C.Monday: A similar situation is forecasted for early Monday but should give way to partly cloudy skies during the day with light N winds and surface freezing levels. Tuesday: A ridge of high pressure is gaining strength bringing dry and cold temperatures.

Avalanche Summary

Several natural loose dry avalanches size 1 and 2 were reported on S and N aspects in the Coquihalla area.

Snowpack Summary

In the Southern part of the region, the recent storm snow has been redistributed by light to moderate winds from the SW to the N to create soft slabs in the alpine and at top of treeline. Warm temperatures at the beginning of the storm have created a good bond between the new snow and the crust. This new snow would also be sitting on a surface hoar layer on N aspects below treeline.In the Northern part of the region, 5-10 cm of recent snow has fallen over various surfaces, hard windslabs in the alpine, suncrust on S aspects and surface hoar in sheltered areas. There continues to be a concern for deeply buried layers of weak facetted crystals, this is mostly a concern on slopes with a shallow and variable snowpack in the Duffey Lake and Chilcotin areas.
