Regions

Glacier.

Another sunny day will heat up solar aspects, increasing the hazard until the clouds move in

Weather Forecast

Solar input again for most of the day, freezing level rising to 1500m. Skies will cloud over this afternoon with up to 5cm falling this evening and overnight with wind shifting to the SW and becoming strong. Tomorrow snowfall will continue with light W wind and falling temperatures. Tuesday the snowfall is due to decrease ahead of a weak ridge.

Snowpack Summary

Surface crusts exist on all aspects to 1300m and on SE-W into the alpine. Surface hoar has been developing over the last few nights to 3mm with shady sheltered pockets in the trees up to 10mm. Wind affected surfaces in exposed tree line and the alpine vary from impenetrable to skis to punchy in places.

Avalanche Summary

Numerous sz 1 - 1.5 and a few sz 2 loose wet avalanches observed this week. A glide slab release also occurred naturally overnight on the 20th on the S side of Cheops, sz 1.5.

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

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Sunday

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.
