New storm snow and strong winds will make dangerous avalanche conditions, especially at higher elevations.
Stick to low-consequence, conservative terrain.
Recent snow and wind has created storm slabs that will be deeper and and more likely to trigger on leeward and cross-loaded slopes.
No new avalanches reported, but we suspect a natural avalanche cycle occurred and suspect touchy storm and wind slabs will exist on Tuesday.
The recent storm brought up to 30 cm of new snow building fresh storm slabs at upper elevations. Expect to find deeper deposits of wind loaded snow on leeward slopes. The new snow sits 40 to 70 cm above a layer of weak, feathery surface hoar crystals.
A 2 to 10 cm thick rain crust can be found down 50 to 100 cm at 1400 m and below.
At treeline we expect a snow depth of 250 cm or more. Snowpack depth tapers with elevation to around 50 cm at valley bottoms.
Many early season hazards are just below the surface below treeline.
