Avalanche Summary
On Monday, avalanche reports were limited to a few size 2 wind slabs on southerly aspects that were triggered naturally and by explosives. Wind slabs may remain reactive to human triggers in specific areas, such as the immediately lee of ridges and sun-exposed slopes.
Snowpack Summary
Strong winds over the weekend had an extensive effect in exposed terrain. Expect scouring and wind slabs in unusual places, as the winds shifted from west to northeast during the arctic outbreak. Sunny weather is likely making the snow extra touchy on south-facing slopes. The mid-December facet/surface hoar layer can be found buried 30-60 cm deep. This layer has been unreactive recently, although snowpack test suggest it may still be possible to trigger in shallow snowpack areas. The lower snowpack is well bonded and features a thick rain crust near the ground that appears to be dormant.
