Seek out sheltered snow that hasn't been pressed or redistributed into stiff slabs by recent winds. Deep and unsupported deposits will remain unstable over the short term.

Avalanche Summary
No new avalanches were reported in the region on Monday.Reports from Saturday and Sunday showed recently formed storm slabs reactive to skier traffic and ski cutting, producing numerous small (Size 1, 20-35 cm deep) storm slab and loose dry releases. Observations from the north of the region on Monday showed especially touchy conditions, with numerous soft storm slabs releasing very easily on terrain over 35 degrees.
Snowpack Summary
Monday's continuing storm brought 20-40 cm of new snow to the surface above about 1700 metres with depths that increase with elevation. The greatest accumulations occurred in the south of the region. The snowpack at lower elevations is now capped by a new rain crust and only light new snow amounts. At higher elevations, strong southerly winds have been redistributing the new snow deep deposits and cornices in leeward terrain. Including the new snow, storm snow totals since mid-January have reached about 150 cm.Below this depth, you'll begin find a few crusts that were buried during the first few weeks of January. Due to limited observations, not much is known about the current reactivity of these layers.The lower snowpack includes the more well-documented mid-December crust layer. Persistent slab avalanche activity from the Whistler area late last week suggests that heavy triggers like a large storm slab or cornice release may carry the risk of triggering this layer in isolated terrain - particularly in the north of the region where it has shown prolonged reactivity in snowpack tests.
