In sintesi

The avalanche hazard is moderate above 4000 feet.  Human triggered avalanches are possible less than 1 foot in depth on slopes that have been recently loaded by wind. Natural avalanches are unlikely.

    The latest storms effects largely stayed to our west with only a few inches of accumulation for our forecast area.  Winds were observed to be moderate to strong over the last 24 hours at upper elevations.  Today it will be possible to encounter shallow wind slabs in specific locations that have formed over the last 24 hours.  Winds shifted from northerly to southerly yesterday, shallow wind slabs could exist on a variety of aspects at upper elevations.

    New wind slabs may be deposited on a layer of faceted (weak) snow that formed during last weeks' clear and cold.  This weak snow will make even shallow slabs more sensitive than they typically would be.  The most likely place to find this problem will be at upper elevations on the lee side of ridges or in cross loaded terrain.  Watch for signs of instability such as shooting cracks and collapsing that would indicate unstable snow.

    In areas that have received more than 8 inches of snow in the last 24 hours the hazard will be higher. In areas were the snow surface is unaffected by recent wind and accumulations were minimal, the avalanche hazard will be low.

Avalanche Discussion

Over the last month our area has developed a stable snowpack without the presence of persistent weak layers that could be affected by a person or machine.  Any instabilities that are present, will currently exist at the surface.  Our area has not received significant snowfall in 10 days allowing the snowpack to settle.

Instabilities may still be present at upper elevations were recent wind slabs may have formed.  Pay attention to new snowfall amouts and the winds affect on the surface of the snow.  Keep in mid that even small avalanches can have big cosequences in extreme terrain or above terrain traps.

Glide cracks are opening up and have released lately in the Maritime zone.  Avoid traveling beneath glide cracks.  See the Maritime section for more information.
