Storm slabs are beginning to bond. Wind slabs have formed on north aspect terrain near ridge crests. Expect the likelihood of avalanches to increase with exposure to sun.
Manage your terrain choices during period of sun and warming temperatures.
Expect the chance of triggering an avalanche to increase on solar aspects.

On Monday a small (size 1) slab avalanche was skier-controlled on an east aspect at treeline. On Sunday a snowmobiler triggered a large (size 2) slab avalanche near Mt. Tod. Check out the MIN report here. On Saturday 1 small (size 1) natural avalanche was reported near Vernon in steep unsupported terrain. On Friday many small to large (size 1 to 2) wind slab avalanches were triggered by explosive control work in the region.
35 to 50 cm of snow overlies a supportive crust.
Two weak layers of surface hoar and/or faceted grains associated with a crust from late January and mid-February may be found 80 to 100 cm deep.
The mid and lower snowpack is well settled and strong.
