Snowpack

Sunday’s fresh and drifted snow has bonded well with the existing snow surface. Especially in the regions exposed to the most precipitation in southern Grisons, avalanches may in places still be triggered in fresh and drifted snow.

In particular on north-facing slopes above approximately 2800 m and generally in the high Alpine regions, near-ground layers have become faceted. As demonstrated by avalanches that have been triggered, in these regions avalanches can start in the old snowpack and sometimes become large.

As a result of sunshine and warming temperatures during the day, gliding avalanches and loose snow avalanches are to be expected.
