Special Announcement

We are currently issuing advisories 5 days a week until our final advisory on Thursday, April 30th.  Advisories will be posted at 7 am each day except Mondays and Wednesdays.


The Bottom Line
  • UPDATE for Wednesday April 15th, 7am:  

    Turnagain Pass has seen 19" of new, low density, snow in the past 19 hours!!
     This is great news for those still interested in winter but caution is warranted if you are headed out in the backcountry. The avalanche danger has risen to CONSIDERABLE for wind/storm slab and loose snow avalanches associated with rapid loading of new snow. Sluffs will be large and high volume and slabs could be as thick as 2' or more on windloaded slopes; the good news is the ridgetop winds have been moderate from the East (20-30mph) with gusts in the 40's. The 24-48 hour rule applies today - this means let the new snow settle out and bond for a day or two before getting on the steep slopes.  

 The Pass is expecting another 2-4" today intermixed with some clearing skies. Ridgetop winds will be 10-15mph from the East.

 See yesterday's Avalanche Advisory HERE which speaks to the storm snow instabilities that will be seen today, Wednesday.

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
