The Bottom Line

Another beautiful sunny day is expected.  Cold, clear, and calm.  Avalanche potential will be LOW, with only minor sluffing noted in the last couple days.  

Temperatures remained cold enough yesterday that our new surface should still be fairly soft and dry.  The exception to that may be south faces that got a direct hit by sun, and a sun crust may be found.  


Primary Concern

The only evidence of recent moving snow that we know of is loose snow sluffing.  This activity appears to be all low volume and minor in size.  With a couple days since the storm, surface snow will now be more settled and consolidated and more difficult to cause additional sluffing.  

The backcountry really does look nice out there.  6 inches of new snow fell on the old tired surface early this week.  This refresh isn't enough to keep you from feeling the old snow underneath, but it is enough to improve conditions.  Combined with sunny skies, the backcountry is a fairly safe and pleasant playground today.

Mountain Weather

The last storm was on Tuesday when 6-8 inches fell at Turnagain Pass and Girdwood.  This has now settled to 4-6 inches.  

Temperatures remained cold yesterday, below freezing in the mountains despite the sunny skies.  Overnight temperatures dipped to teens and single digits.  Clouds are rare in our current high pressure pattern.

We can expect sunny skies for today and tomorrow, and a change to stormy weather on Saturday night.  

 

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.
