Weather Forecast
Snowfalls will begin to taper overnight and freezing levels will drop to the valley bottom. We should see some recovery in the snowpack overnight but it will take a few days for the cool temps to fully penetrate the snowpack. Winds will be SW on Friday with Alpine temps of -10C.
Avalanche Summary
Evidence of a few paths going sz 2 - 2.5 over the past 24hrs. Most of the debris was stopping at the middle or bottom of the tracks of the slide paths.
Snowpack Summary
Freezing levels were around 2600m on Wednesday evening and finally began dropping late thursday afternoon. So far lower elevations have seen a large decrease in snowpack depths due to warm temps and rainfall while treeline depth are still around 1m. The recent rapid loading caused a natural avalanche cycle with many paths going sz 2-2.5 failing on either the Halloween crust or the Oct 17th melt freeze crust. As this layer freezes overnight we will now start to have a new layer in the snowpack. The November rain crust. Conditions will tighten up with teh cooling overnight but it will take afew days for teh cooler temps to penetrate the snowpack.
