No recent avalanche activity has been reported on Wednesday. Avalanche hazard will be on the rise with forecast snow and wind.
Recent storm snow accumulations total 30-40 cm of low density fluff. Forecast snow for Thursday will add to these totals and likely have a poor bond to the underlying snow surfaces which consist of crusts, dry snow or surface hoar on north aspects above 1500 m. Deeper in the snowpack (50-80 cm down) a weak layer of surface hoar buried mid-February may exist. This interface is dormant, but could wake up with a heavy load like a cornice fall, human triggers from a thin, shallow area on the slope or a rapid warm up. Digging towards the bottom of the snowpack youll find a combination of crusts and facets that are reportedly widespread.
