Strong southerly winds may be forming fresh reactive slabs on lee slopes.
Seek out sheltered terrain where the snow hasn't been affected by wind.
Strong southerly ridgetop winds are forecast for overnight and though Sunday which will likely build fresh and reactive new wind slabs on lee northerly slopes.
In the past few days, reported avalanche activity has been limited to small size 1 dry loose sluffs. With strong southerly ridgetop winds in the forecast, reactive new wind slabs may form and be triggerable on Sunday.
If you are heading into the backcountry, please share any observations with the Mountain Information Network.
Up to 5 cm of new snow may fall on Sunday. New wind effect will likely be building throughout the day if forecasted strong winds arrive. Unconsolidated soft snow will likely still exist on wind-sheltered slopes.
A couple of layers of surface hoar/facets or a crust are buried 20 to 45 cm deep, largely depending on aspect and elevation. These layers have been dormant, but they may become possible to trigger in isolated areas where enough of a slab forms overtop.
The remainder of the snowpack is well consolidated, containing several more crusts, none of which are considered a concern at this time.
