    Isolated pockets will persist in typical areas of the Alpine like ridge tops, exposed features, or ledges above ice climbs.

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
