6:30 AM UPDATE: Heavy snowfall, wind, and warm temperatures are building dangerous slabs on a widespread weak layer.
Today is a day to avoid avalanche terrain.
Storm slabs will continue to build through the day. Expect hazard to increase as you find deeper snow. We are unsure how well the new snow will bond with the underlying crust.
Mixed precipitation may cause wet snow to rapidly accumulate at some elevations.
On Tuesday, numerous size 1 to 1.5 wet loose avalanches were reported.
We expect a widespread avalanche cycle to occur where the incoming precipitation falls as snow.
A widespread crust has formed on the surface that is thicker on sun-exposed slopes.
Below this, the upper snowpack is a mix of moist and well-settled snow with deeper pockets in wind affected areas over a crust.
The mid/lower snowpack is generally well settled and strong.
