Turnagain Pass Avalanche Forecast
|
![]() ![]() |
Overall our snowpack has good stability. The only concerns we’ve been seeing are in the layers near the surface – in the top 2 feet. Some areas at higher elevation that received more snow recently in addition to wind loading could have pockets of triggerable wind slab.
Watch out for specific wind loaded features. Small and shallow 1-2 foot deep avalanches are possible.
Most areas that have not been affected by wind loading will have a low avalanche danger today.
Recent Activity
We got a report yesterday of a skier triggered avalanche on Raggedtop in Girdwood. The slide was up to 2 feet deep, 50-75 feet wide, and large enough to bury a person. See the full description on the observations page.
The wind slab problem has been evident over the last few days in specific wind loaded areas. Keep in mind that this issue is not found everywhere, but should be expected on certain terrain features. Wendy’s picture from yesterday is a good example of terrain that holds the wind slab potential.
With an increased north wind expected in the weather forecast today, we will see more of that soft light surface snow blowing around and creating more wind slab. This problem is going to get a little worse today.
Yesterday we were able to get soft snow to sluff in steep terrain. It was fairly low volume, but should be expected on steep slopes and channeled terrain such as chutes and couloirs.
Sluffing is not likely to carry enough volume to bury a person, but it could be dangerous in very steep or high consequence terrain.
Sunny skies are forecasted today. Temperatures this morning are in the single digits, with an expected daytime warming into the mid 20s. A north wind should increase today with channeled outflow wind accelerating through some specific areas. Turnagain Pass will see wind from 12-28 mph. Seward could reach 40mph, and Whittier could see gusts to 60mph.
Fitz will issue the next advisory tomorrow morning, April 13th.
