Avalanche Forecast

Poor - Due to the number and quality of field observations

Some cloud over night with very little or no precipitation and moderate Southwest winds. Cold overnight temperatures around -15 in the alpine. Clearing during the day Monday with slightly warmer alpine temperatures around -10 combined with moderate Northwest winds. Tuesday mostly clear with alpine temperatures around -5. Some moisture starting to enter the picture by Thursday.

A skier triggered a size 1.0 wind slab near treeline on a convex slope in the Whistler backcountry. No other reports from this region.

Surface hoar and near surface facets are reported to be growing during the cold and clear weather. Strong Northeast outflow winds developed windslabs 10-40 cm deep since Friday. Heavy precipitation gave way to clearing skies and rapidly cooling temperatures early on Friday morning. Most areas saw heavy rain up to at least 2000 m this week. Above this it's possible that dense storm slabs and fresh cornices formed. Where it did rain, the snowpack is probably frozen solid with a dusting of fresh snow on top. The lower elevation snowpack has also thinned significantly. A weak layer of facetted snow on a crust was buried around 50-60 cm deep before the rain. This weakness may have been flushed out or may now be bridged by a solid ice crust; however, there is no new info on this interface so it would be wise to investigate its existence and strength before venturing into bigger terrain.
