    First indicators of this problem showing up. Easy enough to avoid but, larger slides, triggered in the deep weaknesses can quickly become a significant issue for groups traveling in the valley bottoms or run outs.

    This problem is still a concern in the Whistler/Portal Creek area. This, along with most recent rain means this area will be in very poor shape for travel.

Weather Forecast

Mild alpine temperatures to -2 with freezing levels rising to 1900ms. Trace flurries starting Wednesday morning. Gusty SW winds through the day.

Snowpack Summary

Moist surface snow and, where a shallower snowpack exists, isothermal conditions BLT on solar aspects. Overall, the snowpack is shallow but there is significant variation through-out the forecasting area. The persistent slab, down 30-70cms has been most active in the surrounding area off the ski hill. This layer can be triggered from thin spots.

Avalanche Summary

Nothing new to report.
