Avalanche Forecast

Fair - Forecast snowfall amounts are uncertain on Thursday

Overnight and Thursday: The next strong pulse of moisture is forecast for Wednesday night, and is expected to continue during the day on Thursday. 10-15 cms overnight and another 20-30 cms during the day. Warm temperatures are not expected to lower overnight, and freezing levels should remain at about 1600 metres.Friday: The Pacific moisture feed should end by late morning as the Low pressure system tracks Northward up the coast. Temperatures and freezing levels should begin to lower. Chance of some broken skies in the afternoon.Saturday: Continued unsettled weather in the wake of the storm. Poor confidence in weather scenarios for Saturday.

Natural avalanches were reported up to size 1.5 early in the storm before poor visibility and travel conditions limited observations.

A new storm slab is developing due to strong Southwest winds, new snow, and warming temperatures. The new storm snow has buried a thin layer of new snow and wind transported snow that is covering a widespread layer of surface hoar that developed during the recent clear weather. Sun crusts also developed during the clear weather on solar aspects up to about 2000 metres. Some areas had strong winds before the surface hoar was buried, so the distribution may be specific to sheltered and shaded terrain features. There is still concern for the buried weak layer of surface hoar from February 12th that is now down more than a metre in most places. The forecast new load of snow and wind may overload this deeply buried weak layer in areas that did not slide after the last storm.
