Avalanche hazard exists primarily in alpine bowls, gullies and ridgelines where the snowpack has survived the recent rain, and new snow is being wind loaded over a slippery crust.
Strong west winds are loading new snow into leeward features in wind-exposed terrain. Wind slabs will be especially reactive where they sit over a slippery crust.
No new avalanches have been reported. Wind slabs sitting on a crust are expected to be reactive both naturally and to rider triggers.
10 to 30 cm of recent snow sits over a thick crust or directly on the ground in areas where the snowpack was washed away by the recent rain. In exposed terrain, the recent snow has been redistributed into lee features by strong west winds.
In the high alpine, greatest snowpack depths are in the range of 1 m. Elsewhere, most areas are below threshold for avalanches.
