Avalanche Activity

Weak layers in the upper part of the snowpack necessitate caution and restraint. In addition a latent danger of gliding avalanches exists.

Weak layers in the upper part of the snowpack can be released in some places by individual winter sport participants. This applies in particular on very steep sunny slopes above approximately 2600 m. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. In some cases the avalanches are large. The fresh wind slabs can still be released in some cases in particular on very steep shady slopes above approximately 2400 m. Caution is to be exercised in particular adjacent to ridgelines in high Alpine regions. More gliding avalanches are possible, even large ones in isolated cases. This applies in particular on steep grassy slopes below approximately 2600 m. Areas with glide cracks are to be avoided.

Snowpack Structure

High altitudes and the high Alpine regions: The northwesterly wind has transported a lot of snow. Faceted weak layers exist in the top section of the snowpack, in particular on very steep sunny slopes above approximately 2600 m. Field observations and released avalanches indicate the existence of a weak snowack. Towards its base, the snowpack is largely stable. Low and intermediate altitudes: The old snowpack is wet and its surface has a melt-freeze crust that is strong in many cases. The high temperatures as the day progresses will give rise to slight moistening of the snowpack. This applies on very steep sunny slopes.

Tendency

Weak layers in the upper part of the snowpack necessitate caution and restraint. In addition a latent danger of gliding avalanches exists.
