Recent snow and moderate to strong southwest winds are expected to build reactive slabs. These slabs may avalanche more easily where they have formed over a hard crust.
Start on small slopes and check the bond of the recent snow to the crust below before committing to larger or steeper terrain.
Wind loaded slopes will be the most concerning.

No recent avalanches have been reported.
With continued moderate snowfall and wind, we expect that human triggered avalanches will be possible on Wednesday.
No recent avalanches have been reported. If you are heading into the backcountry, consider sharing your observations and posting a MIN.
Another 10 to 20 cm of new snow is expected to fall at upper elevations by the end of Tuesday, most of it coming through the day with moderate southwest ridgetop wind. Expect to find deeper deposits on leeward features.
The new snow falls on settling snow, possibly moist or wet below 1300 m.
RIght up to mountain tops, a widespread, thick and hard crust is now expected to be buried by 30-60 cm of snow.
The snowpack below the crust is strong and bonded with no layers of concern.
There is little to no snow below 1000 m.
