Avalanche Problems ?

Problem Details

Saturday’s snowfall was cold, dry, and fluffy, which makes a weak base for the wetter snow expected to fall today. Rising temperatures and increased loading of heavy, wet snow will provide a trigger for natural avalanches today, mainly in steep, wind loaded areas. Stay out of avalanche chutes and steep gullies, where snow tends to funnel and can pile up deep.

Natural and/or human triggered avalanches will tend to occur on slopes steeper than 25 degrees. The sliding surface will be density interfaces within the new snow, or the new/old snow interface where areas of buried surface hoar reside. Some slides may step down to wind slabs 30-60cm deep, which could lead to large and deadly avalanches.

 

Recent Avalanche Activity

Recent Weather

Saturday’s snowfall totaled 10-15″ with high snowfall ratios (dry snow). A strong front will hit the coast from the gulf today, with sub-tropical moisture and increasing south winds. Snowfall should increase through the day, becoming heavy after noon. Temperatures will be rising, with snow levels reaching 1000ft near town this afternoon, perhaps staying at valley bottom up the highway. 1 – 1.5″ of liquid equivalent is expected, adding up to an additional 10-18″ above snowline. Waves of moderate-heavy precipitation will continue through Wednesday, with snow levels between 0 and 1000 feet.

Additional Info & Media

Even small slides can pile up deep. Stay out of gullies, depressions, and terrain traps. ALWAYS wear a beacon, shovel, and probe and know how to use them.
