Storm snow likely remains rider triggerable. Watch for deeper and more reactive deposits in wind affected terrain and remember surface hoar may be present in sheltered terrain
The new snow will take time to bond to the old snow surfaces. In wind sheltered and shaded terrain preserved surface hoar may be present, increasing reactivity.
A mix of conditions produced a variety of avalanches on Saturday, with loose wet at low elevations, and loose dry or storm slab at higher elevations where snow remained mostly dry. With more snow received Saturday night, we expect avalanche activity to have increased.
Around 30 cm of storm snow has fallen in the last 3 days. Low elevations received mostly rain with wet snow at higher elevations. This sits over a mix of sun crusts, surface hoar in wind-sheltered terrain, and wind-affected snow.
The middle of the snowpack is generally expected to be well-settled and stable. Total snow depths vary from 100 to 150 cm at treeline.
