Weather Forecast

Periods of snow, at times heavy. Accumulation in Icefields: 18cm overnight Thursday, with a further 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, 18cm at the time of report, (potentially a further 30cm), will change everything. The existing upper snow pack continues to settle over surface hoar, now down 30cm. Solar aspects have buried surface sun/temperature crusts at TL and below. Below that, a strong mid-pack sits over a deep persistent weakness.

Avalanche Summary

Poor visibility through the forecast region. No new avalanches observed or reported. Help forecast - share observations HERE, on the Mountain Information Network!
