Avalanche Summary
No new avalanches have been reported on Friday. Snowpack test reports have shown that there may be instability within the storm snow that fell this past week.
On Thursday, there have been reports of widespread wet loose avalanches throughout our region on all aspects below 1500 m. Even with cooling temperatures, this may continue into Friday.

Snowpack Summary
Around 45 of recent snow now sits on a variety of surfaces. It will have been redistributed at higher elevations by southerly winds.
A melt-freeze crust formed in mid-January is now buried 60 to 80 cm deep. At the moment this layer is gaining strength. The snow below this layer is consolidating nicely. Buried up to 120 cm is another layer of concern, a crust, formed near the end of December.
Snowpack depths are below seasonal averages. Total amounts range from 150 to 200 cm at treeline, but decrease significantly below 1500 m.

Moderate to strong southerly winds will have developed fresh wind slabs at higher elevations. Expect to find wind slabs in exposed areas that are also below the treeline.
Wind slabs may be sitting on a crust making them especially reactive to ridder triggering.
Aspects: North, North East, East, South East, South West, West, North West.
