30-40cm new snow on Wed/Thurs followed by another 5-10cm Friday and continuous wind transport from the Western directions will have created a considerable danger of windslab conditions lee to the W and NW above 2000m. Enough snow will have accumulated down to nearly 1000m to also affect any lee slopes with pre existing snow on them.

Alpine level
High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
With the new snow accumulation loose but dry sluffs coming out of steep terrain are a likely occurrence. Where these run for a long distance they will in turn likely trigger wet slides as elevation decreases. These types of avalanches often run to the valley floor in spring, so pick your lunch spot carefully even if there is no snow where you are standing. Later on Saturday and Sunday as the next front comes through this danger will rise once more.

Recent Avalanche Activity

Recent Avalanche Activity
No reports of avalanching due to conditions making observations difficult but expectations are that there will have been an active cycle over the last 48hrs

Current Snowpack Conditions

Current Snowpack Conditions
Still very much a winter snow pack with several layers and up to 60-80cm new snow of varying densities in the last few days and plenty of wind transport.

Mountain Weather

Mountain Weather
A brief clear period overnight Friday and early morning on Saturday will close out again by Saturday afternoon.
Strong NW winds and by Sunday the precipitation is going to be heavy again with snow to low (circa 1000m) levels
