Description:
With forecasted snow showers over the coming days, isolated pockets of storm slab lee to the SW winds may produce large orographic lift. We are forecasted for low volumes of accumulation in the coming days but any new snowfall will be landing on either rock or a thin weak pack in the West. Patchy visibility may occur so be aware of snow coverage as you cross a slope. Look for signs of activity in steep shaded slopes across the South where pockets of storm slab may have cross loaded into gullies.

Recent Avalanche Activity

Recent Avalanche Activity
No recent activity has occurred in the backcountry over the last week as conditions remain unchanged and stable across all aspects and elevations.

Current Snowpack Conditions

Current Snowpack Conditions
Continued variable conditions exist across all aspects and elevations. Below 1700m a firm surface produced by a brief period of rain early in the week has left a slick icy surface this has combined with warm temperatures on Thursday . At higher elevations the Westerly half is striped back to rock in exposed areas. The East has multiple crust facet combinations through the mid and lower pack. Near the surface a 20cm layer of decomposing fragments overlies a firm ice crust where the snow has been protected.

Mountain Weather

Mountain Weather
Clouds will come into the region from lunchtime on Friday as winds come around to the Southe West. Freezing levels will fall as we prepare for a period of snowfall and low visibility.Winds may increase in the coming days as snowfall continues into Saturday.
