The Chugach National Forest Avalanche Information Center (CNFAIC) issued an avalanche advisory for Friday for dangerous conditions in Girdwood, Portage Valley, Turnagain Pass and Summit Lake.

A combination of high winds and precipitation this week has raised the avalanche danger above the treeline to "high," meaning natural and human-triggered avalanches are likely above 2,000 feet in Turnagain Pass, Girdwood and Portage Valley. Remotely triggered avalanches are also possible. 

Elevations below 2,000 feet have "considerable" avalanche danger. The CNFAIC warns about the areas where dry snow transitions to wet snow saying an "avalanche from above will be unsurvivable." 

There is also a threat in Girdwood for roof avalanches. CNFAIC reports several roof avalanches Thursday and encouraged people to pay attention to children and pets and where you park your car. 

If planning on doing any hiking near Portage or Placer Valley, know that large avalanches above the treeline may send debris over hiking trails, such as the Byron Glacier Trail. 

A Facebook post by the Friends of the Chugach National Forest Avalanche Information Center also mentioned the warning Friday morning.


Crews were working on avalanche mitigation near mileposts 100 to 83 of the Seward Highway and milepost 5 on Portage Glacier Highway on Friday.
