Recent snowfall amounts are highly variable across the region. Human triggered slabs remain a concern at upper elevations where recent snow has accumulated, especially in wind-affected terrain.
The weekend's storm delivered 20-60 cm across the region. The combination of new snow and extreme southerly winds has likely left reactive slabs in steep terrain at higher elevations.
Lingering flurries continue until Tuesday afternoon.
MONDAY NIGHT: Cloudy with flurries bringing up to 5 cm in the north and up to 10 cm in the Cascades, moderate west wind, treeline temperatures drop to -6 C.
TUESDAY: Some isolated flurries in the morning then some clearing in the afternoon, moderate northwest wind at ridgetops, treeline temperatures around -6 C.
WEDNESDAY: Mostly sunny, light wind, treeline temperatures around -8 C.
THURSDAY: Flurries with 5-15 cm of snow, strong southwest wind, treeline temperatures around -6 C.
Sunday night's storm likely resulted in a natural avalanche cycle in many parts of the region. Preliminary reports suggest there were some very large (size 3-4) natural avalanches in the Cascades, while there are no reports from other parts of the region at the time of publishing. The snowpack is likely gaining strength quickly, but steady wind loading will probably leave slabs reactive to human triggering at upper elevations.
Weather stations suggest snowfall amounts from the weekend are 30-50 cm in the Cascades, 20-30 cm at the Duffey, 30-50 cm northwest of Pemberton, and 10-20 cm in the Chilcotin. In all parts of the region, alpine terrain will be heavily wind affected after strong to extreme southwest winds. Freezing levels reached 1500 m during the storm, so expect a rain crust at lower elevations. Recent weather has helped strengthen the lower snowpack including previous layers of concern.
