Avalanche Forecast

Moderate - Forecast snowfall amounts are uncertain

Moderate southwest winds and 3-5 cm of new snow overnight. Winds becoming strong from the west during the day on Saturday as a weak ridge of high pressure builds after the storm. There may be some sunny breaks Saturday afternoon, but more likely to clear overnight. Freezing levels bouncing between valley bottoms and 1400 metres. Mostly sunny on Sunday with light winds and freezing levels up to 1200 metres. Cloudy with increasing southwest winds on Monday.

Wind loading followed by solar radiation resulted in a size 3.0 natural storm slab avalanche on a south aspect in the alpine on Friday. Another natural cornice fall size 2.0 was reported on Thursday from a north aspect in the alpine, it was also reported that this cornice did not release a storm slab on the slope below. On Wednesday a natural cornice fall resulted in a size 2.0 avalanche.

Another 5-15 cm of new snow was reported on Friday morning. Each pulse of snow and wind continues to add to the wind slabs and settling storm snow from the past few days. About 40-60 cm below the surface, you'll likely find a melt freeze crust. This crust exists in most places except for higher elevation shaded terrain. In many areas there seems to be a reasonable bond between the crust and the overlying snow. I'd still keep an eye on this interface as it has become reactive on some features. Surface hoar buried in early January now lies up to 180cm below the surface and has become less of a concern. Possible triggers for this deep and destructive layer include a large cornice fall or significant warming.
