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
Snow depths are highly variable across the region; however, slopes below treeline are below threshold for avalanche activity. A dusting of loose snow overlies a widespread rain crust that is reported to exist up to about 2100m in the Spearhead/ Fitzsimmons area. Where the near-surface crust is robust (>1cm thick), the upper snowpack has gained strength and avalanches have become much less likely. I'd be extra cautious in areas where the near surface crust is thin or has not formed (I'm thinking high alpine terrain). In these areas, deeper persistent weak layers may exist and may still be sensitive to human triggering.
