Recent Avalanches: A small human triggered wind slab avalanche was reported in the Snug Harbor area yesterday. It is likely that natural avalanches occurred during this wind event and have yet to be reported.
We are expecting a quiet day of weather, but several avalanche problems remain on our radar. The main concern is the lingering chance of triggering a large avalanche failing on weak snow buried 2 to 6' deep. While this has become very unlikely in most locations, it is still a concern in isolated terrain. The natural avalanche outside of Girdwood last week was a key indicator that the layer has not gone away, and it's worth keeping in mind as you travel.
This problem is most concerning in areas with a thin snowpack. This would be most likely in terrain that has been previously wind-scoured, but from what we have been tracking over the past few weeks this is becoming very unlikely.
Loose Snow Avalanches: Chances for loose snow avalanches will increase as south-facing slopes heat up through the day. The relentless winds from the past weeks have locked up snow surfaces, which will limit the extent of any activity. These will be most likely on solar aspects with rocks or trees, especially in terrain that has any soft snow on the surface.
Cornices have grown large over the past week, and will be heating in the sun for the next few days. As always, avoid spending time under this overhanging hazard as they can release unexpectedly.
