Snowpack Summary

Around 25 cm of new snow has fallen over the weekend, accompanied by light to moderate wind. Wind is expected to be strongest through passes and gaps in the mountains on Tuesday.

The new snow overlies 20 to 40 cm of mostly faceted snow sitting on a weak layer from late January. The weak layer consists of a crust on sun-exposed slopes, and a layer of surface hoar or facets on all other aspects.

The mid and lower snowpack is generally well settled.
