Avalanche Forecast

Moderate - Timing or intensity of solar radiation is uncertain

Overcast on Wednesday with flurries or light snow, moderate southerly winds, and freezing levels rising from valley bottoms overnight to about 1200 metres during the day. Overcast with light snow on Thursday combined with light wind and freezing levels rising from valley bottoms up to 1300 metres. On Friday, sunny periods with scattered or broken clouds, moderate southwest winds, and freezing levels rising up to 1500 metres.

On Monday we had reports of a natural cornice fall size 2.5 and a storm slab size 2.5 both from northeast aspects in the alpine at about 2100 metres. I suspect that wind slabs continued to be touchy on Tuesday.

Moderate southwest winds and 5-10 cm of new snow added 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.
