New snow and strong winds have formed wind slab at higher elevations. Strong wind means that wind slabs could be found further down slope than expected.
Continuously verify conditions as you move through terrain.
Avalanche hazard will vary from aspect to aspect and at different elevations.
New snow and strong winds have formed wind slab at higher elevations. Strong wind means that wind slabs could be found further down slope than expected.
Large avalanches could be triggered from thin spots or with a large load, like a cornice fall.
Wet loose avalanches are likely when the snow surface feels wet or slushy.
At the time of publishing we had not received reports of new avalanches but we expect that natural avalanche activity may have occurred in the region on Monday.
Over the weekend, explosive control has produced small wind slabs.
15 to 30 cm of new snow overlies a crust at lower elevations. At treeline and above this new snow has been redistributed by strong southwest wind, forming deep deposits on north and east facing terrain.
Within the top 100 cm of the snowpack, there are a few layers of surface hoar, facets, crusts, or a combination of the three.
The remainder of the snowpack is well settled and strong.
