Problem Details

In areas where the new snow is drifted deeper than 6″ storm slabs will begin to become a concern. Expect the new snow to be moving around on steep slopes and manage this potential danger accordingly. Be on the lookout for any areas that are wind affected, as any fresh wind slabs will be tender. Convexities and slopes steeper than 30 degrees should be treated with caution.

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

Over 11″ of precipitation fell from November 5th – 15th. Snow levels were between 1000 and 3500ft. Up to 12 feet of wet snow fell above treeline, and has settled to a 2-3 meter deep base at 4000ft, and around 70cm deep at 2800ft. Temperatures plummeted to the single digits and teens after the last storm.

Around 4-8 inches of new snow fell Friday-Friday night. Not much in the way of wind with the current system. Light snow is expected to continue today, increasing tonight as a stronger storm moves in.

Saturday night-Sunday we expect around 10-15″ of somewhat moist snow. Winds will be southerly, but snow levels should remain at valley bottom. 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.
