Turnagain Pass Avalanche Forecast

Image of Tincan at 3pm Sunday, Nov 5th after 3″ dusting of snow.  Turnagain Pass is still very thin – snowpack from 0″ to possibly 1′ at the high elevations, even 2′ where the winds have blown in snow.

In anticipation of the next storm, we are expecting the cold weather to break down the existing snow and turn it to facets (bad news for the base of a snowpack). Hence, we will be mapping out where and how thick the older snow is to assess future avalanche potential. Hint: photos of slopes, valleys, ridges, etc are a great way to help us with this! What about the wind? There is cold air pushing down from the interior which will create strong winds in Southcentral. Turnagain Pass may be spared but other areas may not. Winds can increase avalanche hazard by rapidly loading slopes – and on that note, we’d like to remind folks about  some  early season avalanche tips.

Early season hazards:

Rocks, alders, crevasses and  avalanches.  

Little snow. Keep it simple. What to clue into:

1)  Rapid changes in weather? This includes recent or current snowfall, wind, rain on snow and warm temperatures after a storm. One layer of snow can be a slab!  

2)  Recent avalanches in the past 1 or 2 days?

3) Cracking, collapsing, whumphing?   (see photo below)

4) What are the consequences if the slope does slide? Will you go off a cliff? Into a crevasse? Over the rocks? Are there other terrain traps?

**Remember the Crow Pass trail crosses several avalanche paths and even a small early season storm can produce slides that run over the trail.

A little over a 2 foot snowpack at 5,000′ at the head of the Milk Glacier. Location of a very large whumph. The top 10″ layer of harder snow is suspected to have collapsed into the weaker faceted snow below (classic set up for slab avalanches). (Mike Records photo)

Final thought for this update: *THINK COLD POWDER!!!!

Special Announcements

Winter is on the doorstep!!   ARE YOU READY FOR THE 2017/18 SEASON???

Have you dusted off your gear…? What about your avalanche rescue gear? Have you been checking the  observation page? What about our  weather page?? Don’t be fooled by the low snow cover, avalanche season has begun in certain areas – check out this observation from the  Crow Pass trail on Saturday, Nov 4th.  Turnagain Pass is still very thin – conditions at Sunburst HERE. Yes, cold, dry and windy weather is forecast this week, but keep your fingers crossed – snow can be just around the corner.

The Chugach National Forest Avalanche Center has just open its doors and is gearing up for the season. All staff are returning – yay! This is, Heather Thamm, Aleph Johnston-Bloom, Graham Predeger and Wendy Wagner. We will be issuing intermittent updates on this page until enough snow falls to warrant daily avalanche forecasts in the Turnagain Pass area. During this time, our observation page will house the most up to date information along with  our Facebook and Instagram pages (Facebook link in the upper right corner and Instagram: @chugachavy). So please,  send us  your photos, videos or notes to help us map the early season condtions!

Mark your calendars:

• Tuesday, Nov 14th:    CNFAIC updates, understanding the avalache advisory and a look at lessons learned in the backcountry.
         6:30-8:30pm at Ski AK in Anchorage

• Thursday, Nov 16th:    Friends of the CNFAIC Fall FUNdraiser  – Don’t miss this chance to support your  avalanche center and get inspired for the season listening to  Mark and  Janelle Smiley’s amazing  adventures!!!   8pm at the Beartooth Theater Pub
