Unfortunately there is still quite a bit of uncertainty, so take the following precipitation and wind speed values with a grain of salt. SUNDAY NIGHT: Freezing level around 1000 m, strong southwest wind, 2 to 8 cm of snow possible.MONDAY: Overcast, freezing level holding around 1200 m, moderate to strong southwest wind, a trace of snow possible.TUESDAY: Overcast, freezing level holding around 1200 m, moderate southwest wind, 1 to 5 cm of snow.WEDNESDAY: Overcast with potential for some clearing in the afternoon, freezing level holding around 1200 m, light southwest wind, 1 to 5 cm of snow.
Avalanche Summary
On Friday loose wet avalanches to size 1 were reported as storm snow slid on the April 4th crust. A few natural size 1 to 1.5 wind slabs were reported Saturday morning. If you're out we'd love it if you would submit what you're seeing to the Mountain Information Network.
Snowpack Summary
10 to 40 cm of storm snow now rests on a weak layer buried April 4th which consists of crust, surface hoar and facets. The crust is widespread and up to 4 cm thick. Spotty surface hoar and facets have been reported on top of the crust on high elevation north facing slopes. Moderate to strong wind generally out of the south over the weekend likely formed fresh slabs which may remain sensitive to human triggering Monday. North facing alpine terrain also has a layer of facets down 40 to 100 cm below the surface, but this layer has not been recently active and is likely trending towards dormancy.At and below treeline the snowpack is isothermal throughout much of the forecast region.
