Avalanche Summary

On Monday, numerous wind slabs were easily triggered by the weight of a person up to size 1.5. With continued outflow winds and cold air natural avalanche activity will taper off but human triggered wind slabs remain possible through Wednesday.

Snowpack Summary

40-50 cm of new snow from last weekend has been redistributed by strong southwesterly winds initially and now northerly winds. This sits on a crust on all aspects except north and possibly a mixture of weak feathery surface hoar or sugary facets in isolated sheltered terrain at treeline and below. The remainder of the snowpack is generally well-settled.
