Regions: Sea To Sky.

The storm continues! Conditions are improving but don't let your guard down just yet.

Weather Forecast

It just gets better and better for the south coast.  THURSDAY: 10-15cm new snow, moderate south winds, freezing level at 1000m. FRIDAY: clear, moderate easterly winds, freezing level at 1000m. SATURDAY: another 15-20cm, strong south winds, freezing level at 1000m.

Avalanche Summary

There have been reports of a widespread avalanche activity from the Whistler area that is likely indicative of what is going on in the rest of the Sea to Sky region.

Snowpack Summary

As much as 100cm of new snow have fallen at upper elevations since the weekend. At lower elevations heavy rain on Tuesday probably formed a new crust that is now buried as deep as 30cm. Strong southwesterly winds have loaded lee features at ridgetop. Below tree-line snow depths are probably still below threshold for avalanches although I expect we'll be crossing that line soon. 

Avalanche Problems

Storm Slabs

Storm and wind slabs will likely remain susceptible to human triggers for the next couple of days especially in wind loaded features or steep slopes where the new snow sits above a crust.
If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 5
