Weather Forecast

Periods of snow, at times heavy. Accumulation in Icefields: 14cm overnight Thursday; 20cm on Friday; 8 -10cm Saturday. Temps drop over the day Saturday with an overnight low of -28. Valley bottom freezing levels. Mostly light SW winds, gusting at ridge tops. A detailed mountain weather forecast is available from Avalanche Canada.

Snowpack Summary

Forecasted storm snow over this weekend (potentially up to 50cm), will change everything in the snowpack. The existing upper snow pack continues to settle over surface hoar, down 5-10cm deep. Solar aspects have buried surface sun/temperature crusts at TL and below. Below that, a strong mid-pack sits over a deep persistent weakness.
