The Bottom Line

Current snowpack conditions as we head into the latter part of November are thin – very thin. Few folks have made it south of Anchorage for snow recreation and are instead venturing north with the bigger early season snowfall. That will change……right…..it’s only November after all.

A snapshot of our snowpack both above treeline and below are seen in the photos below. The majority of the snow is very loose and unsupportable, except for areas that have seen recent wind.

Avalanche Problem 1
  • Wind Slabs

Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
More info at Avalanche.org

For anyone venturing into the Turnagain area mountains, wind slab avalanches are what to watch for. Despite the strong northwesterly winds during the last 24 hours, which did a number around Turnagain Arm, there is still plenty of loose snow available to blow around. This can be attested to by the lack of wind damage above 3300ft on Tincan today. The wind slabs I did see were at the mid elevations, very stiff and cracking just around my feet. However, they were sitting on faceted snow and though I didn’t find any in the few starting zones I was able to get to, I’d keep a look out for them. Winds are forecast to continue over the weekend from the north and northeast. Below is a picture of the mid elevation wind damage:

Weather
Sun, November 17th, 2013

This past week most of Alaska’s wet weather has been just to our north. The temperatures did climb mid-week, up to 32F at 2,500′, but are on their way back down to the teens now. The last 24 hour winds have been moderate to strong from the northwest. These should continue to be moderate with strong gusts from the north and east for the next several days or more. This will do a good job of ushering in the cold temperatures that are on tap. Our next chance for snow is not in the foreseeable future.

The National Weather Service in Anchorage has done a great job at summing up the weather for next week:
