Small-area snowdrifts and wet-snow avalanches during daytime: caution

Small-area snowdrifts and wet-snow avalanches during daytime: caution

Fresh snowdrift accumulations have been generated this weekend which are often prone to triggering. One sole winter sports enthusiast can trigger mostly small slab avalanches in these zones. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. Less danger on steep grass-covered slopes with sufficient snow, isolated medium-sized glide-snow avalanches still possible. With daytime warming and solar radiation, small-to-medium wet-snow avalanches are possible in steep terrain.

Nighttime hours initially will have good outgoing longwave radiation, later on it will be reduced due to heavy cloud. Especially on sunny slopes the uppermost layers will moisten during the daytime hours due to diffuse radiation and low-lying clouds. In addition, rainfall at intermediate altitudes will weaken the snowpack. were foehn-impacted and warm, often reducing outgoing longwave radiation so that only a breakable crust could form. In addition, light rainfall up to intermediate altitudes. Below 1500m there is little snow on the ground. Shady slopes at high and high-alpine altitudes were impacted by strong-velocity foehn winds over the weekend, the newly generated snowdrifts were deposited atop an unfavorable old snowpack surface, which is stabilizing gradually.

In the evening hours, showers will taper off, only high-altitude residual clouds will persist. Tuesday will begin dry with variably visibility due to fog and low-lying clouds, with some sunshine expected. In the latter part of the day, convective cloud build-up and a tendency towards showers will increase, snowfall level at 1600m. At 2000m: +1 degree. Only light winds.

Glide-snow and wet-snow avalanches still possible, despite lower temperatures
