Turnagain Pass Avalanche Forecast

![]() ![]() |
Stability is excellent across the region, and avalanche danger will start off the day as LOW at all elevations. The small amount of new snow 2 days ago did build some shallow windslabs, but nothing very notable or dangerous was reported yesterday. Late in the day south aspects should be approached with more caution if the temperature ramps up today. Wet loose avalanches are possible due to sun exposure at lower elevations.
Get out and enjoy the backcountry this weekend. Snow quality is variable, but pockets of powder can be found if you avoid the sun crust.
Small pockets of wind slab were found occasionally yesterday from the 4-5 inches of new snow that fell on Thursday. Loose snow sluff in the non-wind affected snow was also common, but less of an issue if you use good sluff management technique. Wind slab is most likely found at higher elevations, below ridgetops, and in steep terrain. Both the slabs and the sluffs are shallow and low volume, so as avalanches by themselves they are not a huge concern. The bigger concern is related to the consequences of the terrain such as cliffs or no-fall zones.
Cornices remain a low probability but high consequence avalanche problem. These large overhanging features have the potential to produce the largest avalanches today. Choose your lines to avoid cornice exposure, and always give them a wide berth when traveling on ridge crests.
It’s mid March already. The sun has some significant power that has already built a series of crusts on south facing slopes. As the temperatures rise this afternoon, wet loose snow may start to move at lower elevations on south exposures. Cold temperatures this morning may delay the wet cycle, and any cloud cover will also prevent the surface snow from warming.
Yesterday was one of those perfect Alaska days. Today looks like more of the same. Temperatures are cold this morning, reaching negative temperatures in a few places. Most areas are comfortably in the teens. As soon as the sun hits we can expect rising temperatures for the rest of the day. Partly cloudy skies are forecasted. Wind should be almost non-existent.
We can expect a similar weather pattern for the rest of the week with no major storms on the horizon.
Wendy will issue the next advisory on Sunday, March 17th.
