LOW avalanche danger exists for all elevations. Avalanche activity is unlikely, not impossible. Isolated areas of unstable snow may exist. Normal caution is advised.

    No specific widespread avalanche problems are expected today. Any isolated areas of instability that do exist will most likely be small to medium size wind slabs that formed near or above treeline during the recent periods of strong to gale force NE ridgetop winds.

    Look for clues such as wind pillows, test slope cracking, and snow surface texturing/shaping (sastrugi) to identify possible areas of wind slab formation. Apply normal caution for backcountry travel in avalanche terrain. Communicate with travel partners and identify possible areas of concern. Expose one person at a time on or below steep slopes. Avoid regrouping below steep slopes or in avalanche run out zones.

Avalanche Discussion

Observations made and received yesterday from around the forecast area reported isolated areas of blowing snow above treeline. In these areas new wind deposits were small. No new wind slabs of significant size were reported. The snowpack continues to show signs of settlement and consolidation following the last storm cycle. Widespread areas of wind scouring have been noted above treeline. Areas of near surface facets and surface hoar have been noted in wind protected areas below treeline.
