Points saillants

Avalanche conditions will continue to become more dangerous today. Expect wind drifts to be large and easily triggered in exposed areas above 8,000'. Expect these slabs to be 2 feet thick and easily capable of burying a person. Slabs may be even thicker, and firm, in some areas and may break upslope above you.  Triggering an avalanche today is likely in most areas not sheltered from the wind.

    Winds slabs were easily  triggered yesterday and will remain sensitive to triggering today. These slabs grew in size overnight as snow fell and will continue to grow in size today with more snowfall and increasing southwest and west wind. Beware of wind loaded areas at the base of cliffs and at the exits of steep gullies where wind driven snow has accumulated. In prime areas like this, slabs could be up to three feet thick. Consider your exposure to larger slopes due to the potential for natural to occur without a human to trigger, especially later in the day as more snow falls and winds increase.

    Dry loose avalanches on steep terrain over 35° will occur easily today and could carry you or trigger thicker slabs. Recent snow has fallen on a variety of different snow surfaces with the potential for all the new snow to move quickly and easily upon the old snow surface below. Perform quick hand shear tests and assess how the recent snow is bonding to old snow surfaces.

    A small wind slab in northwest facing terrain off Cardiac Ridge at 9,600’. The slab failed on old snow down about 14”. Expect avalanches like this to be up to twice as thick today.

    Given the quantity of recent snowfall and the precipitation type changes observed yesterday, it would be wise to assume storm slabs may be sensitive to triggering in very steep, wind sheltered locations. Assume this snow is guilty until proven innocent. Look for shooting cracks in the snow surfaces and test small slopes before committing to larger ones.

    A small soft slab involving only the top 4-6” of recent snow. Northeast aspect at 8,900’. More snow overnight and today will increase the size of slabs like these.

Avalanche Discussion

Don't be fooled by the light snow and grass showing in the valleys. Someone shook the snow globe to ring in the Ides of March. The riding will be excellent today following the recent warm and dry weather.  Avalanche danger will continue to be elevated as this unsettled weather remains in place for several days.
