Be wary of wind slabs in steep terrain and minimize your overhead exposure during the heat of the day.
New wind slabs formed at higher elevations from 10 to 15 cm of new snow and strong westerly wind. Assess for slabs on steep slopes near ridges before entering high-consequence terrain.
Wet loose avalanches are possible with strong sun. Watch your overhead exposure to steep sun-exposed slopes during the heat of the day. Also be wary of cornices, as they may weaken with daytime warming.
We haven't received any recent reports of avalanche activity. Looking forward, avalanche activity is possible on Monday at higher elevations. Humans could trigger wind slabs in lee terrain features near ridges. Warming and intense sun will wet the snow on sun-exposed slopes, increasing the likelihood of wet loose avalanches and cornice falls.
Around 15 cm of snow accumulated above 1200 m on Saturday. The snow fell with strong westerly wind, which may have formed wind slabs in lee terrain features near ridges. The snow fell onto wet snow and a hard melt-freeze crust. Warming and periods of strong sun will rapidly wet the snow on sun-exposed slopes.
The remainder of the snowpack is strong.
There is insufficient snow to form avalanches for most below treeline locations.
