Highlights

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

    Snow and strong winds are likely to build storm slabs on a variety of slopes. The size and likelihood of these is expected 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 20-30 cm is forecast, easing to light snow on Wednesday. On Wednesday night and Thursday, another 20-40 cm of snow is forecast. The freezing level is expected to fluctuate, but peak at around 1500 m. 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

The snowpack is highly variable across different aspects and elevations. So far, we only have limited information from the field. Initial reports suggest that there is around 150 cm at 2000 m. Recent winds have scoured exposed slopes, and left variable wind slabs and crusts. In some places, a crust/facet interface or surface hoar can be found in the upper snowpack. At high elevations, a crust which formed early season may exist near the base of the snowpack. Incoming snow may bond poorly to this cornucopia of surfaces.
