Caution urged towards snowdrifts with increasing altitude
At higher altitudes the freshly-generated and older snowdrift accumulations are prone to triggering in some places, easily triggered as small-sized, in isolated cases as medium sized slab avalanches. Danger zones occur behind protruberances in the landscape, in gullies and bowls, and on freshly wind-loaded slopes. Magnitude and spread tend to increase with ascending altitude. Avalanche headquarters currently has little data from outlying regions about the snowpack, for that reason a cautious on-site evaluation is important. Below the treeline, avalanche danger is low. Isolated danger zone for small triggerings (slides) are possible in steep terrain. The risks of being swept along and forced to take a fall need to be considered.
Snowpack
By Monday evening, 5-10 cm of fresh snow is anticipatedd. It will be deposited on a largely well consolidated old snowpack surface showing marked effects from wind. Knolls and ridges are often completely windblown, gullies and bowls often filled to the brim with snow. With ascending altitude, mostly small-to-medium snowdrift masses are evident, particularly in ridgeline and pass areas. They are only moderately well bonded in themselves and also with the old snowpack surface, making them prone to triggering.
Tendency
Starting on Tuesday it will turn intermittently sunny, but remain quite cold. Thus, no significant change in danger levels is expected.

Caution urged towards small-sized snowdrifts
Above the treeline, fresh, mostly small snowdrift accumulations require caution. Isolated danger zones for small avalanche triggerings (slides) in steep terrain and freshly wind-loaded slopes are possible. Avalanche headquarters currently has little data from outlying regions about the snowpack, for that reason a cautious on-site evaluation is important. Below the treeline, no marked avalanche problem is evident.
Snowpack
By Monday evening, 5-10 cm of fresh snow is anticipated widespread, to be transported by winds. Often the snowfall will be deposited on bare ground. At high altitudes it will be deposited on a well consolidated old snowpack with marked effects of wind influence. Above the treeline and with increasing altitude, fresh, generally small snowdrift accumulations are evident, particularly in ridgeline and pass areas.
