Rhemes Valley

Wind slabs represent the main danger.

Wind slabs represent the main danger.

As a consequence of the sometimes strong wind the already large wind slabs will increase in size additionally. These are to be found in all aspects. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. The fresh and somewhat older wind slabs are in some cases prone to triggering, caution is to be exercised on very steep slopes at transitions from a shallow to a deep snowpack. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger. As a consequence of warming during the day and solar radiation small and medium-sized natural dry avalanches are possible.

30 to 50 cm of snow, and up to 60 cm in some localities, has fallen since Tuesday above approximately 2200 m, in particular along the border with France. Up to 2200 m rain has fallen. The strong wind has transported the new snow. These weather conditions on Friday gave rise to unfavourable bonding of the snowpack in some places in particular along the border with France below approximately 2500 m. Naturally triggered avalanches and artificially triggered avalanches have confirmed this situation. The snowpack will be generally subject to considerable local variations. In all aspects snow depths vary greatly above approximately 2000 m, depending on the infuence of the wind.

The weather will be sunny. The avalanche danger will decrease gradually.
