We're only expecting a few cm of new snow Saturday which shouldn't change avalanche danger much. As riding conditions improve remember that open creeks, just buried logs, stumps, rocks and nasty alder are all present in the mountains right now. 

Summary

Confidence

Low - Uncertainty is due to the limited number of field observations. Forecast precipitation (either snow or rain) amounts are uncertain.

Weather Forecast

It’s late November and it looks like we’re entering a more winter-like pattern this weekend. 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.

FRIDAY NIGHT: Trace of snow possible, freezing level near valley bottom.

SATURDAY: Overcast, freezing level around 900 m, moderate southwest wind, 1 to 10 cm of snow possible, with another 1 to 5 cm possible Saturday night.

SUNDAY: Scattered cloud cover, freezing level around 1000 m, light to moderate northwest wind, 1 to 5 cm of snow possible.

MONDAY: Scattered cloud cover, freezing level around 500 m, light to moderate northwest wind, 1 to 5 cm of snow possible.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

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

Storm Slabs
