Avalanche Forecast

Fair - Timing or intensity of solar radiation is uncertain on Monday

Synopsis: After agonizing over weather products all morning, I'm convinced that freezing levels will exceed 2500m by Monday afternoon, and likely stay there until Wednesday morning. There's been a lot of talk about when the big warm up would finally happen, and it looks like well be staring down the barrel of it for the next 48 hours.Monday: Freezing Level: 1500m rising to 2200m - 2600m; Precipitation: Nil; Wind: Treeline: Light, SW | Ridgetop: Moderate, SWMonday Night: Freezing Level: 2500mTuesday: Freezing Level: 2400m - 2600m; Precipitation: Trace; Wind: Treeline: Light, SW | Ridgetop: Strong, SWTuesday Night: Freezing Level: 2500m lowering to 1500mWednesday: Freezing Level: 1500m - 2000m; Precipitation: 4:8mm - 4:15cm; Wind: Treeline: Moderate, NW | Ridgetop: Strong, NW

No new avalanche activity was reported on Saturday.

Recent warm temperatures have resulted in good settlement and bonding of the storm snow from last week, but you may find the odd skier triggerable wind slab on north through east facing aspects at and above treeline.Three persistent weak layers exist in the highly variable snowpack of the Columbias:The mid-March sun crust/surface hoar layer down 50-80cm still has potential for human-triggering in isolated areas. The early-March crust/facet/surface hoar layer down around 80-120cm has become less susceptible to human triggering, but still has the capacity to produce large avalanches.The mid-February crust/facet/surface hoar combo is typically down 60 - 120cm. Direct triggering of this layer has become unlikely, however, cornice fall, a smaller avalanche in motion or prolonged warming may wake this layer up, which would result in very large and destructive avalanches.Weak basal facets exist in many areas, but triggering is unlikely.
