Avalanche Forecast

Fair - Timing, track, or intensity of incoming weather system is uncertain

A series of moist westerly systems from the Pacific continue to affect the interior regions. A low pressure system will cross the interior Saturday night/early Sunday morning resulting in more precipitation with strong to extreme winds. Sunday should be relatively dry before another system crosses the interior on Sunday night/Monday morning. A third storm is expected for Tuesday.Sat. Night/Sunday: Snowfall 10-15cm easing in the morning, freezing level rising to around 1200m in the afternoon, ridgetop winds 50-70km/h SWMonday: Snowfall 15-20cm starting Sunday night, freezing level rising to around 1400m in the afternoon, ridgetop winds 50-70km/h SW easing in the afternoonTuesday: Snowfall 6-10cm, freezing level rising to around 1300m in the afternoon, ridgetop winds 40-60km/h SW

A widespread natural avalanche cycle has been occurring across the forecast area over the last few days with natural avalanches up to size 3.5 as well as skier triggered avalanches up to size 2.

Snowfall amounts have varied across the forecast region, but up to 100cm of storm snow is settling into a cohesive slab which is now typically 50-80cm thick. This slab is sitting on the weak Feb 9 interface which consists of multiple layers of surface hoar, faceted snow, and/or crusts from the past few weeks of cold clear weather. Reports indicate very easy snowpack tests results and widespread large destructive avalanche activity. Due to the persistent nature of these buried weaknesses, touchy conditions are likely to exist for some time.Strong ridge top winds have created wind slabs on leeward features at treeline and above. These wind slabs are the primary concern for the near future and strong-to-extreme forecast winds over the next few days are expected to add to this problem.For the most part, the mid and lower snowpack are strong and well consolidated.
