Glacier.

If the sun stays out this afternoon the hazard will increase significantly

Weather Forecast

Sun, warm temperatures and rising freezing levels again today. High of -7 and freezing level rising to 1300m. Becoming cloudy in the afternoon with light flurries possible. A low pressure system is due to move over the province tomorrow night bringing mod - strong SW wind and up to 15cm new snow by Monday morning.

Snowpack Summary

The snow surface has been affected by intense sun and the freezing level rising to at least 2100m yesterday. At treeline and above exposed terrain was heavily affected by the wind last weekend and varies from impenetrable to skis to punchy in places, especially where facetted by overnight cold temperatures.

Avalanche Summary

Numerous sz 1 - 1.5 loose wet avalanches observed yesterday and a few sz 2s. A glide slab release also occurred naturally overnight last night on the S side of Cheops, sz 1.5.

Please report backcountry avalanche observations using the Avalanche Canada Mountain Information Network.

Confidence

Timing or intensity of solar radiation is uncertain on Saturday

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
