Regions: Jasper.

Light flurries and SW winds forecast for the region. Generally trace amounts of new precip which is not expected to overload the existing snowpack.

Weather Forecast

Wednesday morning, expect sunny periods and isolated flurries in the afternoon with only a trace, up to ~4cm of new snow. Alpine temperatures: Low -15 C, High -8 C.

Snowpack Summary

Surface faceting continues with cooler temperatures. Previous winds have stripped snow from all exposed terrain creating hard wind slabs and wind affected snow in any open terrain. The mid-pack is supportive. Decomposing surface hoar is found down 40cm to 80cm in isolated sheltered locations.

Avalanche Summary

Field team reports no new avalanche activity observed.

Dig down to find and test weak layers before committing to a line.

Aspects: All aspects.
