Avalanche Summary
No new avalanche activity has been reported, but this lack of information does not represent benign conditions. Watch for the presence and sensitivity of storm slabs to increase with elevation and please post your observations to the Mountain Information Network (MIN)
Snowpack Summary
50-60 mm of precipitation fell over the region over Wednesday, accompanied by moderate to strong winds and freezing levels around 800 metres. Under these conditions, new snow accumulations of up to 60 cm may now form our upper snowpack at upper elevations. New snow depths and wind effect will increase with elevation. Although the composition of the mid and lower snowpack in the region is uncertain, rapid loading of the upper snowpack carries the potential to activate weaker layers that are likely to have formed during the early season.
