The Bottom Line
  • The CNFAIC will be issuing intermittent snow and avalanche updates as conditions warrant through mid-November. 
  • Daily avalanche forecasts are planned to begin on Thanksgiving weekend - unless cooler storms bring enough snow to increase avalanche concerns before then.

Tuesday Nov. 13th update:

The dreaded Pineapple Express rolled through Southcentral Alaska Sunday and Monday (Nov 11/12)... This not only brought heavy rain to 3, 4 and even 5,000 feet, but 10 inches of it to the Portage Valley area (Bear Valley RWIS)! If it was only in the frozen form... That said, the 1-2 feet of snow that existed around treeline has been degraded to patches of mush and bare ground. Many wet avalanches occurred during the storm in the higher elevations, taking what snow there was available down the mountainsides. 

For this week, mild temperatures and clearer skies are forecast through Thursday with another shot of rain/snow on Friday night into the weekend. It's still too early to say, but models are showing this weekend's system bringing a rain/snow mix for road levels and possibly 6 inches to treeline and above. Check back for Saturday morning's update - in the meantime think cold thoughts!

If you head out into the mountains to higher elevations harboring colder snow, be on the look out for Red Flag warnings:

  1. Recent avalanches
  2. Cracks in the snow that shoot out from you
  3. Whumpfing (collapsing) of the snowpack
  4. Rapid changes in weather (snow/rain/wind/temperature)

Avalanche Problem 1

We are focusing each early season update on one of the Know Before You Go 'GETS'.  Today's GET is GET OUT OF HARMS WAY  (check out the Know Before You Go video link in case you haven't seen it).

Part of GETTING OUT OF HARMS WAY is knowing the terrain we are in, how we are approaching that terrain, where people in our group are and ways to minimize bad outcomes in the event an avalanche occurs. Read the points below. These are ways we stack the odds in our favor!

 


This is a general backcountry avalanche advisory issued for Turnagain Arm with Turnagain Pass as the core advisory area (this advisory does not apply to highways, railroads, or operating ski areas).

Winter snowmachine use open/closed status and riding conditions updates

Riding status is not associated with avalanche danger. An area will be open to motorized use in accordance to the Forest Management Plan when snow coverage is adequate to protect underlying vegetation. Backcountry hazards including avalanche hazard are always present regardless of the open status of motorized use areas.
