carefully assess new snowfall amounts as you move through terrain. Convective flurries can result in localized significant snowfall and increased hazard.

Avalanche Summary
On Thursday explosive control produced storm slab avalanches up to size two. No other significant avalanches were reported.
Please post your field observations and photos on the Mountain Information Network. .
Snowpack Summary
20 to 50 cm of storm snow sits on wind affected surfaces at all elevations. Deeper deposits may be found in north and east facing terrain features due to southwest winds.
The mid-snowpack is generally well settled. The lower snowpack includes a layer of weak sugary crystals near the ground. These facets are slowly gaining strength and have not produced recent avalanche activity. We continue to track the layer and watch for any signs that it could wake up and produce very large avalanches.
