Slightly higher avalanche danger at high altitudes

Slightly higher avalanche danger at high altitudes

Mostly low danger prevails, moderate danger at high altitudes. Fresh drifts are still trigger-prone at high altitude and on steep shady slopes. A small-to-medium slab and in steep terrain also loose-snow avalanche can be triggered by 1 person. Such danger zones will increase with ascending altitude. Snowdrift masses in steep terrain should be avoided. In backcountry terrain, a cautious route selection is imperative. On very steep and rocky slopes, slides and loose-snow avalanches can be expected during the course of the day due to solar radiation. Glide-snow avalanches can trigger at any time of day or night and grow to larger size. Avoid zones below glide-cracks.

25-30 cm of fresh snow is expected at high altitudes by Wednesday evening, amid moderate winds, which will generate fresh small snowdrift accumulations, bonding well with the old snowpack surface. Soft layers and surface hoar will be blanketed with fresh snow. Bonding will be only moderate. The old snowpack is compact and stable, at low and intermediate altitudes wet down to the ground.

Nocturnal hours: Gray skies, persistent rainfall/snowfall above 1000 m. In early morning the snowfall level will ascend to 1500 m.. Wednesday daytime: Cloudy, often heavy snowfall in the morning. In afternoon, the snowfall will taper off, clouds disperse from the west. At 2000 m: -4 to -1 degree. Light-to-moderate N/NW winds.

Intermediate high-pressure front will make it very sunny, mild, with only light winds. Warmth and solar radiation will lead to moist slides and loose-snow avalanches. Avalanche danger levels are not expected to change significantly.
