The storm has ended and good riding can be found in sheltered areas. Watch for slab formation if you venture into the Alpine or gully features.

Weather Forecast

5cm of new snow on Sunday and expected to taper off by early Monday morning. Monday will bring mainly cloudy skies an alpine high of -9 and light winds from the west. Tuesday will be the start of a clearing trend, cooler temps and minimal amounts of snow.

Snowpack Summary

Recent 25cm of storm snow is settling out, as periods of moderate Southwest winds have formed soft slabs in lee features on a previously buried crust. The crust is down 40-60cm and can be found between 2100-2600m on all aspects and will be a layer of concern as the snow load increases. The lower pack is well settled to ground.

Avalanche Summary

No Road Patrol on Sunday. Skiers in the Parker Ridge area on Saturday reported hearing avalanches in the far distance during the storm. Could not confirm due to poor visibility.

Confidence

Due to the number of field observations on Sunday
