Natural avalanches are unlikely, human-triggered avalanches are possible. Small avalanches in specific areas, or large avalanches in isolated areas.
A small amount of new snow plus some wind brings the possibility of loose snow and windslab avalanches, running on recent melt-freeze crusts.

Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.

Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.
< 2000m
Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.
Up to 15cm of recent snow has fallen on top of a crust in some places, especially on sunny aspects. There is also an older crust on shady aspects below 2800 m. Small avalanches on this layer have been observed in the past week. Keep this in mind when approaching steep terrain with hazards like rocks or cliffs below.
Sensitivity | The specific avalanche problem type is reactive to human rider triggers. Easy to trigger with ski cut. |
Distribution | Many locations. Evidence for instabilities is frequently found, in many locations. |
Time of Day | All day |
Trend | No change |
Confidence | Moderate |
Small areas of windslab will be forming near ridges. They could be up to 30 - 40 cm deep and could run fast on a crust layer below 2800 m.
Sensitivity | The specific avalanche problem type is reactive to human rider triggers. Easy to trigger with ski cut. |
Distribution | Specific areas, with common characteristics. Evidence for instabilities exists, but it is not obvious and finding it requires careful observations. |
Trend | Deteriorating |
Confidence | Moderate |
Weak, facetted snow layers have been found around buried mid-pack crusts and in areas with shallow snow depth. The problem is worse in the north of the region where the snow is shallower. With recent warm temperatures these layers should have stabilised at lower elevations, but remain cautious on steep terrain.
Sensitivity | The specific avalanche problem type is difficult to trigger with a human rider. |
Distribution | A few, isolated locations; evidence for instabilities is rare and hard to find. |

Recent avalanche activity:
Small loose dry avalanches reported on N and NE aspects in high alpine steep terrain February 18th.
Glide slabs continue to be active on multiple aspects (more commonly E, S and W) below about 2600 m, some up to size 2. These can release at any time - if you see cracks in the snow, do not stop under these areas!
Snowpack:
Around 10cm of new snow fell on Thursday, with moderate SW and W winds starting in the afternoon. There is a melt-freeze crust under the new snow on the S half, and on N aspects a strong icy crust from last week's warm temperatures lies buried below up to 20 cm of dry snow, below about 2800 m. Buried crusts with weak snow layers around them might still be present in some places. Watch out for sugary (faceted) snow in areas where the snow is shallow. Warm temperatures have been gradually strengthening the snowpack, but the problem layers should not be forgotten yet. Check out recent snow profiles (or add your own!) at snowpilot.org
The past few days have brought fine and calm weather. Light snowfall is expected on friday, clearing Saturday morning but snow showers returning in the afternoon. Snow totals up to 5 cm. Moderate S winds. Freezing level 1600 metres.
