Kernpunkte

Changing conditions: snow and strong winds make a good recipe for avalanches.

    Größe
    1–3
    Snow and wind are likely to build slabs on a variety of slopes. I expect the size and likelihood of these to increase throughout the week.

Confidence

Fair - Due to the number of field observations

Weather Forecast

A series of low pressure systems is forecast to bring snow, strong southerly winds and rising freezing levels. On Tuesday, 5-10 cm snow is expected. Overnight, another 10 cm is forecast, easing to light snow on Wednesday. On Wednesday night and Thursday, another 10-20 cm of snow is forecast. The freezing level is expected to fluctuate, but peak at around 1200 m. Ridgetop winds are strong to gale from the south-west.For more details check out avalanche.ca/weather

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

So far, we only have limited information from the field. Initial reports suggest that there is little snow below treeline. Recent outflow winds created variable wind slabs and crusts at higher elevations. Incoming snow may bond poorly to this concoction of surfaces. In some places, a crust, surface hoar or facets can be found in the upper snowpack. A persistent weak layer exists at the base of the snowpack in the north of the region, however I am not sure how widespread this is. Information is limited - share yours through the Mountain Information Network.
