Avalanche Forecast

Good

Overnight and Sunday: Some convective energy may cause localised flurries with little accumulation overnight. Convective energy should be reduced on Sunday as the High pressure system moves over the Interior. Expect mostly sunny skies with light Southwest winds and freezing levels rising to about 1300 metres. Strong solar radiation may cause moist snow up to 2100 metres on Southerly aspects.Monday: The surface ridge of High pressure should stay mostly intact as it slides a bit to the East. Expect mostly sunny skies with light Southwest winds and freezing levels rising to about 1400 metres.Tuesday: Some cloud is expected to drift into the interior from a weak disturbance on the coast. There is a chance of flurries that may accumulate a couple of cms.

Natural cornice falls up to size 3.0 were reported from Thursday. Some of these avalanches entrained a lot of snow in the tracks, but did not step down to deeply buried weak layers (March 10th surface hoar/facet ).

Cornices are reported to be very large and weakly bonded. Natural cornice falls are a concern during daytime warming. Cornices may also be triggered easily by travelling near them. Slopes with corniced entrances, or exposed to cornice falls should be avoided with these conditions. Dry windslabs may be found on Northwest thru Northeast aspects at higher elevations. These wind slabs are reported to be improving their bond to the old surface, but may continue to be triggered by skiers and riders. Loose moist or wet snow may fall naturally out of very steep terrain on sun exposed slopes. Small loose snow avalanches may trigger the recent storm snow slab where it is moist from solar heating and sitting on a planar sliding surface like an old sun or rain crust. The weak layer of buried surface hoar from March 10th is down more than a metre in most places, and is reported to require hard forces to result in resistant failures in snow profile tests. The lower snowpack consists of well bonded layers that are well settled and strong.
