Fresh and reactive wind slabs will develop over the day. Step back into conservative terrain choices as snowfall accumulates. Higher snowfall is expected as you travel further west.
Reactive storm slabs will form overnight on Wednesday and continue to build throughout Thursday. Avoid steep open slopes and wind loaded features.
Recent avalanche activity has been limited to small (size 1) loose dry avalanches out of steep northerly aspects.
Fresh snow with strong southerly winds will form deeper deposits in north facing terrain features. Precipitation below 1000 m may fall as rain. New snow/rain falls over dry snow on shaded slopes at higher elevations, and over a crust on south facing slopes and low elevations. New snow bonding to this crust should be suspect.
The middle and lower portions of the snowpack are strong and well-bonded.
