Avalanche Activity

In the Lutak zone, observers on January 19th and 20th reported widespread natural fresh soft slab avalanches on all aspects 30 degrees and steeper. On lower-angle slopes, cracking was also widespread. The new storm snow is sliding on the weak near-surface facets that formed last week (Januray NSF layer).

Please report any observed avalanche activity on our observations page.

Weather

The storm track is anchored right on Haines, and looks to stay that way for a while. We received 12-24″ of snow down to sea level Sunday-Monday, and snow will begin again tonight, lasting through at least Sunday. 24-36″ additional snowfall is expected over the mountains through Sunday, with 12-24″ in the valley bottoms.

December brought 4-9 feet of new snow (highest amounts near Haines,  least amounts at the Pass). Rain levels reached as high as 3000ft briefly at the end of December. Early January brought arctic cold, and very strong NW winds that stripped away a lot of snow at the Pass.
