Small wind slabs may linger in isolated locations below alpine ridgetops.

On Monday, several skier triggered size 1 wind slabs were reported on lee aspects in the alpine.

NOTE: Observations are currently very limited in this region.

Up to 20 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects at upper elevations. Recent westerly wind may have formed small wind slabs on lee aspects at upper elevations.

While weak layers at the bottom or middle of the snowpack have been a concern throughout the season, the current lack of avalanche activity and benign weather suggest they are not a concern at this time. They could become problematic again this spring whenever temperatures rise significantly.

• Carefully evaluate big and steep terrain features before committing to them.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
