Rhemes Valley

Significant warming to below 3200 m: From the early morning as the moisture increases there will be an increase in the danger of moist and wet avalanches.

Fresh snow and large quantities of wind-drifted snow of the last four days remain for the foreseeable future prone to triggering in particular on northwest to north to east facing aspects above the tree line. They can as before be released, even by a single winter sport participant or triggered naturally, in particular in gullies and bowls, and behind abrupt changes in the terrain. Backcountry touring and other off-piste activities call for extensive experience in the assessment of avalanche danger and careful route selection. In starting zones where no previous releases have taken place and in steep rocky terrain many medium-sized and, in isolated cases, large moist and wet avalanches are to be expected as a consequence of warming, in particular in case of releases originating from sunny starting zones above the tree line. In the typical avalanche paths the avalanches can in isolated cases still reach the valleys.

Over a wide area 80 to 130 cm of snow has fallen since Wednesday above approximately 2300 m. The sometimes storm force wind has transported the new snow significantly, especially adjacent to ridgelines and in pass areas above approximately 2600 m. The snowpack will be generally subject to considerable local variations. The high temperatures from the early morning will give rise to significant moistening of the snowpack in all regions.

Up to 40 cm of snow, and even more in some localities, will fall on Tuesday. The avalanche danger will persist.
