    The new snow that is forecasted to arrive will further develop the existing wind slabs that are located in alpine lee areas. Expect these wind slabs to be up to 40cm in isolated areas by Wednesday.

Weather Forecast

Up to 10cm of snow will fall across the forecast region Monday night through Tuesday night. These relatively light accumulations will not significantly increase the danger rating. The wind should remain light until early Wednesday morning.

Snowpack Summary

New wind slabs are sitting on top of older hard wind slabs in alpine lee areas. The middle of the snow pack is quite faceted. The Jan 6th surface hoar can still be found in isolated areas down approximately 30cm. This layer has potential to become active when it receives a considerable amount of load.

Avalanche Summary

No avalanches observed or reported today.

Confidence

Forecast snowfall amounts are uncertain on Tuesday
