Watch for isolated wet loose avalanches on steep sunny slopes when the snow surface is wet
Sun and warm temperatures may melt the surface snow on steep sun-affected slopes, creating the potential for wet loose avalanches. Use extra caution on sun-exposed slopes, if the snow surface is moist or wet.
No new avalanches have been reported. Observations have been limited with no field team in the area this week.
If you head out, please consider posting your observations to the Mountain Information Network.
Open areas and upper elevations saw widespread wind effect from previous strong winds. Wind slabs built up on lee north through easterly slopes but are likely quite stubborn to trigger by now.
A melt-freeze crust can be found on sunny slopes and at lower elevations. This crust will soften and melt with sun and daytime warming.
50 to 70 cm of snow may be overlying a layer of surface hoar in sheltered areas at and below tree line. There is uncertainty with its distribution and reactivity at this time.
The remaining snowpack has no other layers of concern.
Snowpack depths at treeline range from 95 to 250 cm, and there is still very little snow below treeline.
