Summary
Weather Forecast
Today should be mostly sunny and dry, with increasing cloud possible later in the day. The high will be -8 with moderate to strong Northerly winds. Thursday will be mainly cloudy with isolated flurries and a high of -5. On Friday, flurries may (fingers crossed) bring up to 10cm of snow with moderate to strong SW winds and freezing levels to 1700m.
Snowpack Summary
~5cm of snow covers the previous surface of crust, facets, surface hoar and pockets of thin soft slab. Northerly winds on Monday and Tuesday will have transported the new snow, creating pockets of soft slab in the immediate lees of ridges. Overall the snowpack is now well settled and strong.
Avalanche Summary
No new avalanches have been observed in Glacier National Park recently. In the region, small isolated pockets of windslab have been reactive to skiers at ridgetop and the loose surface snow sluffs on steep slopes.
Confidence
Problems
Wind Slabs
Northerly winds early this week created isolated windslabs in unusual places. Small pockets of wind slab have been reactive on steep lee features. These are of most concern on steep, aggressive terrain where the consequences of a fall are severe.
Travel conditions are difficult at lower elevations and in the trees.Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.
Aspects: All aspects.
Elevations: Alpine.
