We're only expecting a few cm of new snow Saturday night which shouldn't affect avalanche danger much, but watch for the formation of small wind slabs near ridgecrest. Open creeks, just buried logs, stumps, rocks and nasty alder are all present in the mountains right 

Summary

Confidence

Low - Uncertainties in both the snowpack structure and the weather forecast limit our confidence.

Weather Forecast

It’s late November and it looks like we’ve entered a more winter-like pattern. The boundary region isn’t set to get a whole lot of snow from this system, but we should get a decent little re-fresh.

SATURDAY NIGHT: Freezing level around 800 m, moderate to strong southwest wind, 1 to 5 cm of snow possible.

SUNDAY: Scattered cloud cover, freezing level around 1200 m, moderate to strong northwest wind, trace of snow possible.

MONDAY: Scattered cloud cover, freezing level near valley bottom, light to moderate northwest wind, no significant precipitation expected.

TUESDAY: Scattered cloud cover, freezing level near valley bottom, light variable wind, no significant precipitation expected.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

The region hasn't picked up much new snow as of Saturday afternoon, but winter is slowly descending to the valleys. This MIN report from the Whitewater Backcountry Wednesday paints a great picture. Total snowpack depths range from about 80 to 100 cm on north facing alpine features. Solar alpine features have about 30 to 80 cm on them. There are multiple crusts in the snowpack, but they've been generally unreactive.

Problems

Wind Slabs

An icon showing Wind Slabs

The storm hasn't produced much new snow as of Saturday afternoon and we're only expecting a few cm overnight which isn't expected to pose much of an avalanche problem. That being said, we're expecting quite a bit of wind Saturday night, so watch for wind slab formation near ridge crest.
