Retreat to mellower terrain if you are seeing signs of instability or rapid loading from new snow and wind.
Avalanche danger will increase through the day as new snow piles up.
Moderate to heavy snowfall is expected to build reactive slabs through the day on Wednesday. Expect slabs to be deeper and more reactive on west and north facing slopes due to moderate to strong southeast winds.
No new avalanches have been reported.
If you are heading into the backcountry, consider sharing your observations and posting a MIN.
30-40 cm of new snow is expected to accumulate at treeline and above by the end of the day on Wednesday. Moderate to strong South or Southeast winds will make deeper, denser deposits in leeward terrain.
Steep south through west facing slopes may have a thin, breakable crust under the new snow.
The thick and strong mid-March crust is now expected to be buried by 50-60 cm of mostly settled snow.
Below this, the rest of the snowpack is wet but well settled and strong.
There is little to no snow below 1000 m.
