Banff Yoho Kootenay

Convective snowfall on Tuesday has deposited variable snow across the region from a few cms in most areas up to 15cm. Generally light winds and warm temps have settled most recent instabilities but concern for small windslabs in steep alpine terrain still exists.

No new avalanches observed or reported on Tuesday

Limited early-season observations indicate a generally well-settled Rockies snowpack with no significant weak layers. Last week's wet snow and rain left a rain crust (Nov 13) to 2300 m. In the short term, this adds stability to the snowpack and with 5-10 cm of dry snow on top, only isolated windslabs have been reported along with good early-season travel conditions. Treeline snow depths range from 40-70 cm.

A small system is passing through the region Tuesday night and is bringing variable snow amounts from 1-15 cm with light winds. Wednesday and Thursday will be sunny and calm with winds picking up throughout the day Thursday. Friday will bring strong to extreme SW winds and the next pulse of snow.

• Wind slabs are isolated, but may remain reactive.
