Recent SW winds have added to existing cornices, this combined with strong diurnal temperature fluctuations could cause cornices to fail and trigger deep instabilities.

Use caution in shallow snowpack areas where deep weakness might be more reactive to a human load. Build trust slowly in the new snowpack before committing to any large rideable slope.
Weather Forecast
Sun and rising freezing levels to around 2000m on Sunday. Winds look to be light south-westerly. A detailed mountain weather forecast is available from Avalanche Canada.
Snowpack Summary
Exposed terrain at TL and above have been hammered with wind. In sheltered terrain the upper snowpack is continuing to settle with warm temps. A generally strong mid snowpack overlies deep persistent weakness' at the bottom of the snowpack. Use caution in shallow areas where these deep weakness might be more reactive.
