The Cold Persists! The good news is that we should receive a light dusting of new snow. Every little bit helps!

Weather Forecast

A light dusting of new snow, between 5.2  and 7.6 cm is expected Thursday night and into Friday. However alpine temperatures will remain low at around -22 C to -18 C. Friday will remain mainly cloudy with isolated flurries, alpine temperatures: -24 C, High -19 C. Winds will remain light Northerly at ridge top until Sunday.

Snowpack Summary

Isolated pockets of wind slab will be found in exposed areas at upper elevations over the old snow interface of facets, crusts, wind effect, or surface hoar. There are 3 crusts, found generally at TL and the alpine, that sit dormant in the snowpack. The Nov 24 crust seems to be providing mid-pack strength over a lower, rotted, Halloween layer

Avalanche Summary

No new avalanches have been reported or observed along the parkway

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

Isolated pockets will persist in typical areas of the Alpine like ridge tops, exposed features, or ledges above ice climbs.
Use caution above ledges and cliffs where small avalanches may have severe consequences.Watch for surface cracking and stiffer surface layers of snow.

Aspects: North, North East, East, South East, South.
