Avalanche Problems ?

Problem Details

The new snow is now around 15″ deep, starting out dry and weak, then getting denser in the middle. On wind loaded slopes, avalanches will be likely on these density interfaces within the new snow. Avalanches may also occur on the new/old snow interface where patches of slick surface hoar are buried. Treat slopes steeper than 30 degrees as suspect, especially ones with heavy wind loading.

You can reduce your risk from storm slabs by waiting a day or two for the snow to settle and bond. Storm slabs are most dangerous on slopes with terrain traps, such as timber, gullies, over cliffs, or terrain features that make it difficult for a rider to escape off the side.


Recent Avalanche Activity

The most recent observed avalanches occurred during the last storm cycle, over a week ago. They ranged from size 1 to 3.5, on a variety of aspects, mostly soft slabs (up to 80cm deep) and loose slides, though a few glide avalanches occurred during the warmest period with rain-on-snow.

Recent Weather

4-8 inches of new snow fell Friday-Saturday. Moderate southeast winds kicked in Saturday night.

Last night’s storm brought an additional 1″ of precipitation. Snow levels started near 1000ft and lowered through the night. Around 12″ of wet snow fell.

A very strong storm is on tap for Tuesday. Stay tuned.

Additional Info & Media

Find ways to minimize your risk when traveling in the backcountry. This means choosing safe uphill tracks, skiing from safe zone to safe zone, and only exposing one person at a time to steep areas. Always travel with a partner trained in avalanche rescue, and carry a beacon, shovel, and probe.
