Highlights

Triggering a large avalanche remains possible in steep (>35 degrees), wind loaded terrain today. Wet loose avalanches may release naturally when temperatures warm mid-day. You'll find great riding on shady and wind-sheltered areas where avalanche problems are at a minimum.  Look for signs of wind-loading and softening snow that is becoming damp in the sun.

    About a foot of new snow has fallen over the past 48 hours in the western and northern part of this forecast zone.  Wind speeds were low enough that these slabs are most likely to be around 12-18" thick and soft, perhaps thicker in prime areas with lots of fetch. Cross-loaded terrain features and areas beneath cliffs, especially those areas impacted by sunshine, will be most sensitive to triggering today.

    A copious amount of snow has fallen over the past few days (~18" since Sunday) with light to moderate wind speeds the past two days. We're starting out with significantly colder temperatures this morning but the high March sun will bear down on southerly slopes and loosen the top several inches of this snow, more at lower elevations and around cliffs and in couloirs. This problem will be pretty obvious with rollerballs, pinwheels and damp surface snow.  These same slopes will refreeze as they enter the shade later today.

    No propagation in this pit though there were several planar interfaces that could be sliding surfaces/failure planes if the upper snowpack slabs up in the wind or sun.

Avalanche Discussion

In the past two days, 12" of snow containing an inch of water was recorded at the Baird snow plot at 8,900'. Most of that snow fell on light to moderate wind speeds and cold temperatures. This lower density snow will change rapidly as sunshine hits the surface. So far, no storm slabs have been triggered in the recent snow despite there being some density changes in the snowpack.
