Conditions Summary

NOVEMBER 10th, 2020

Mostly clear, sunny skies yesterday provided a good opportunity to get a look around. It’s beginning to look more like winter in the Turnagain Pass forecast area. The storm Saturday night through Sunday brought around 2′ of snow to upper elevations in Girdwood and 12-16″ to Turnagain Pass. There were also some strong winds with this system and wind effect was evident, especially in the Alpine. Evidence of a storm initiated avalanche cycle at upper elevations was observed from the road, north and south near Girdwood, as well as slide in Portage.

Prior to this storm the old snow sitting on the ground starting around 1500′ had started to facet and become weaker (sugary). This is easy to feel traveling with your pole and easy to see in a quick pit. Observers noted whumpfing yesterday, especially above 2200′ where the wind effect on the snow was more evident and the snow over the facets more slab like. Finding a steep slope with this structure could be more avalanche prone.  With more snow and wind in the forecast tonight through Thursday, it will be important to remember this weak snow near the ground and watch the overall slab development. The temperatures look to fluctuate in this incoming storm system so there may be some rain/heavy wet snow at lower elevations. Remember to check the Current Weather page for the weather forecast and weather station information.

Snowpack structure at 2000′ on Tincan. Note the weak (facet/sugar) snow near the ground.

Wind effect looking up towards Common Bowl on Tincan. The snow depth is quite variable due to the wind distribution. 11.9.20

A few people have been venturing out. Check out the observations page for both Turnagain and Summit Lake. It is definitely early season conditions at low elevations with shrubbery hazards and rocks. As we are still gathering information about the snowpack, ease into terrain, look for signs of instability, and use good travel protocol. This is also a great time to practice rescue skills!
