Weather Forecast
Winds taper tonight and will be light westerly with very light precipitation, if any, for next couple of days. Mid mountain temperatures will be cooler (-12C for highs and overnight lows of -20C).
Snowpack Summary
Over the past 8 days we've received up to 66 cm (Sunshine region), less East of the divide. We've been hammered by very strong SSW winds leaving widespread soft and hard surface slabs in it's wake, particularly on the E. side of the divide. The Nov crust in the bottom third of the snowpack remains concern, especially after the recent load of snow.
