Weather Forecast

Wednesday: Starting off clear but clouds developing mid-morning. Flurries in the afternoon. Moderate southwest winds. Thursday: Clearing briefly before another weak frontal system moves in bringing 2-5 cm starting late in the day. Freezing levels will rise to around 1000 m. Friday: Models are in disagreement, but light to moderate snowfall, strong southwest winds and freezing levels around 800 m is the most likely scenario at this time.

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

A very light skiff of snow may have buried a surface hoar layer that lies on top of old surfaces comprising crusts and old wind slab. However, with only a centimetre or so of new snow, it's not certain that surface hoar crystals of 5 mm or more would get properly buried. Successive melt-freeze cycles have produced crusts on all aspects at lower elevations as well as on south-facing slopes higher up. The old wind slabs are no longer causing concern in most areas. A facet layer, which formed around 20th January, is buried around 60 cm and is reported to be gaining strength. It showed hard, resistant planar results in a compression test at treeline in the Hankin area on Sunday.
