In sintesi

Very large and dangerous avalanches will occur on Wednesday. Over the last few days we’ve received numerous avalanche observations, including a near miss from a party that thought they were safely out of avalanche terrain. Continue to stay off slopes steeper than 30 degrees, and limit your time or do not travel through low angle terrain beneath steep slopes.

    Very large and reactive wind slabs developed as we received 8.5 inches of water (equaling nearly 4 feet of snow) with strong winds at Heather Meadows since Saturday.  There have been numerous reports of natural avalanches, including the close call from a group of skiers travelling along the valley floor in the Bagley Lakes area of Heather Meadows. This group thought they were far out of avalanche terrain and were surprised by the size and reach of these avalanches.  Check out the video below.  

    Likelihood of triggering an avalanche is decreasing as the storm has ended. Still, natural avalanches are possible and human triggered avalanches are likely. Only one day has passed since the large natural avalanche cycle occurred, so continue to travel carefully. Stay off steep slopes, and make conservative terrain choices. Travel quickly through those avalanche runout areas if you must.

Avalanche Discussion

The avalanche danger dropped to Considerable on Wednesday, but there is still a good chance you will encounter avalanches. Wednesday is the day to head out into low angle meadows with no steep slopes nearby. It’s a great day to be out, as you will probably even see some sunshine, a welcome change after the last week. 

In regards to sunshine, you may encounter wet loose avalanches on steep sunny slopes. Pay attention to the snow as you travel, and if it starts getting moist on those sunny slopes, expect wet loose avalanches to come down. 

During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources.  Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
