Fair - Timing, track, or intensity of incoming weather is uncertain on Wednesday

Tuesday night and Wednesday: The frontal system is pushing its way into the interior and precipitation should start later Wednesday. Between 5 to 10 mm is expected to fall during the day with moderate to strong winds from the SW in the alpine. Freezing levels will lower to valley bottom and the inversion will disappear. Thursday: A break before the next system. Expecting some clearing, winds tapering off staying from the W, temperatures also staying cool and freezing level to valley bottom.Friday: Expecting light precipitation and moderate SW winds.

A few loose avalanches up to size 2 were reported on steep S-SE facing slopes.

The new snow will fall on a variety of surfaces; windslabs in the alpine, facets, surface hoar below treeline in sheltered areas and a suncrust on South facing slopes.  New windslabs and some sluffing in sheltered terrain is expected.  These new layers will most likely be touchy for a certain time.The surface hoar layer below the 40-60 cm of generally well settled snow is still a concern to professionals, especially below 1900 m. in sheltered-shady areas and on S aspects. It still produces sudden planar shears in those areas as well as some resistant planars.  A strong mid-pack overlies a weak facet/crust layer near the base of the snowpack, which is now considered inactive.
