Conservative terrain travel is recommended, as new slabs may form over the day.
New storm slabs may form as snow accumulates on Thursday. It may also remain possible for riders to trigger a weak layer found about 20 to 40 cm deep.
Widespread natural avalanche activity was observed over the past few days during intense stormy conditions. Storm slabs are releasing at high elevations and loose wet at lower elevations.
Looking forward, new storm slabs may form over the day on Thursday. There's also a possibility that riders could still trigger the weak layer of surface hoar described in the Snowpack Summary, which is most likely at higher elevations.
Around 10 to 20 cm of snow is forecast, which will accumulate onto about 20 cm of wet snow. All of this rests on a buried weak layer of feathery surface hoar and/or sugary faceted grains, which may be associated with a hard melt-freeze crust. It is possible that the recent rain destroyed this layer, but it may linger still, particularly at higher elevations.
The middle and base of the snowpack is largely weak and faceted. A hard crust may be found near the ground.
Treeline snowpack depths are variable and generally range between 30 and 80 cm. Snowpack tapers rapidly as you move lower in elevation.
