Avalanche Forecast

The alpine rating is moderate, the treeline rating is moderate, and the below treeline rating is low. Known problems include Wind Slabs.

South Coast Inland.

Windslabs from cold outflow winds are the primary concern; however, given the generally sugary upper snowpack, wind slabs could be found in all sorts of terrain at treeline and alpine elevations.

Avalanche Summary

Wind slabs up to size 1.5Â have been reactive to human triggers on all aspects at treeline and in the alpine. These wind slabs may fail on older firm surfaces or facets approximately 20-50 cm down.

Snowpack Summary

10-20 cm of recent snow covers a variety of old surfaces including sugary faceted snow, sun crusts on steep solar aspects, firm wind affected snow (either scoured or old hard windslab), and possibly even surface hoar in sheltered areas. Strong easterly winds are likely to form windslabs. The key point is the winds have come from a variety of directions and they're often failing on the sugary facets these slabs. Therefore the problem is potentially widespread.The lower snowpack is generally well-settled.

Problems

Wind Slabs

Easterly outflow winds are likely to form a new round of wind slabs, this time around on southwest, west, and northwest facing slopes. Pockets of older wind slabs can still be found on all aspects. Here's a great photo of one from Saturday.

Be cautious as you transition into wind affected terrain.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: All aspects.

Elevations: Alpine, Treeline.
