Lechtal Alps Central

Weakly bonded old snow is to be evaluated with care and prudence. Increase in avalanche danger as a consequence of solar radiation.

Weakly bonded old snow is to be evaluated with care and prudence. Increase in avalanche danger as a consequence of solar radiation.

Weak layers in the old snowpack can still be released in very isolated cases, this applies even in case of a single winter sport participant. Caution is to be exercised in particular on very steep shady slopes above approximately 2200 m, as well as on very steep east facing slopes above approximately 2400 m, especially on little used northeast and east facing slopes. Night: As a consequence of the rain small natural wet avalanches are possible below approximately 2200 m. This applies in particular on shady slopes. As the day progresses the likelihood of wet avalanches being released will increase. As a consequence of solar radiation, the natural avalanche activity will increase. This applies in particular on very steep east, south and west facing slopes below approximately 2400 m.

Up to 2000 m rain will fall in the next few hours. In some localities up to 15 cm of snow will fall above approximately 2000 m. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on east and west facing slopes above approximately 2400 m. Outgoing longwave radiation during the night will be reduced in some case. The surface of the snowpack is frozen, but not to a significant depth and will soften during the day, in particular at intermediate altitudes. Hardly any snow is lying at low altitude. The snowpack will be moist at low and intermediate altitudes.

Tuesday: Hardly any increase in avalanche danger as a consequence of warming during the day.
