Conditions Summary

Sat, November 14th, 2020
With snow starting in the late afternoon yesterday the mountains picked up 1-2″ of light, fluffy snow overnight.  Temperatures are dropping as cooler air is moving into the region. There is a slight chance of snow today and a clearing skies and sunshine on tap for Sunday into the coming week. Winds should remain light for the next few days.

With improving visibility, fresh snow and early season stoke this weekend, it is important to remember that there is now plenty of snow to slide and known weak layer of old October snow. Observers from Girdwood to Summit Lake are consistently hearing and feeling whumpfs and finding a poor snowpack structure above 2200′. It’s worth being suspect of steep slopes moving forward as skies clear and travel in the Alpine becomes easier. Ease into terrain, look for signs of instability, and use good travel protocol.

Persistent Slab avalanches:  Weak October snow is sitting under a slab formed by the 1-3′ of snow from the last two storms. This current snowpack structure has the potential to be triggered by the weight of a skier or rider and cause an avalanche releasing in the facets (sugar snow) at the bottom of the snowpack. This structure becomes a concern around 2,200′ – the higher in elevation you travel the more likely it will be to encounter this issue. Whumpfing and/or cracking are signs this layer is reactive. Snow covered slopes with a 30° slope angle and steeper are suspect. If an avalanche releases near the ground it could result in a very dangerous slide. 

Snowpack structure at 2800′ in Main Bowl/1st Bowl on the backside of Seattle Ridge. Our Extended Column Test propagated at 13 taps on the facets (sugar snow) above the crust. 11.13.20
