Weather Forecast
Variable stormy weather is expected to continue for the forecast period.Tuesday: 10-20cm of snow, freezing level around 1400m, and light ro moderate southerly wind.

Avalanche Summary
Recent reports from the Whistler area include a small 25 cm thick skier-triggered storm slab avalanche on a northeast facing alpine slope running on recently buried facets.
Snowpack Summary
As we begin our forecasting season, we are working with limited information from the field. Early reports suggest there's enough snow for avalanches at alpine and some treeline elevations. Recent snow is likely to have been redistributed into slabs on lee slopes at alpine elevations. This snow may overlie a weak old snow surface (surface hoar, facets and/or a crust) which developed during the recent dry spell. Check the bond of the snowpack at this level and take a cautious approach as new snow builds deeper above this layer.
Problems
Storm Slabs
New snow is building up over a potentially weak old surface interface. Changing winds may leave wind slabs on a variety of slopes.
Avoid freshly wind loaded features.>Caution around convexities or areas with a thin or variable snowpack.>Early season hazards such as rocks, trees and stumps are still visible.>
Aspects: All aspects.
Elevations: Alpine, Treeline.
