Forecasters are working with very little field data at this time. Given the limited information , I would tread cautiously and make continuous observations as I go. If you've been in the backcountry, please share you observations on the

Weather Forecast
Expect moderate northwest winds, increased cloud and freezing levels at about 3000m on Sunday. On Monday, a fast moving Pacific frontal system should bring 10-15cm of snow, moderate to strong southwest winds and freezing levels near valley bottom. A drying trend is expected for Tuesday as a cool ridge of high pressure develops over the region.
Snowpack Summary
Snowpack structure likely varies significantly throughout the region, and slopes below treeline are below threshold for avalanche activity. Limited reports suggest a dusting of low density snow is mingling with surface hoar on shaded slopes. This fragile surface structure overlies a thick rain crust in many areas, and could become a reactive weak layer when new snow falls. For the time being, this rain crust has likely added significant strength to the snowpack making avalanche activity less likely. That said, deeper persistent weaknesses may still be sensitive to human triggering, especially at elevations or parts of the region where the near-surface crust is non-existent.
