    Depending on elevation, this layer is either bridged by a hard mid-pack at higher elevations and likely to be triggered from a shallow area. At the lower elevations there is minimal support in the snowpack and is easier to trigger.

Weather Forecast

Temperatures forecasted to reach above seasonal expectations by midday Thursday. The high pressure and periodic glorious sunshine is forecasted to remain into the weekend and through next week.

Snowpack Summary

Warmer temperatures at TL and below are promoting settlement in the snowpack. Recent new snow has been redistributed by strong SW winds creating wind slab in open areas at all elevations.  This sits over a supportive mid-pack at higher elevations. There is a weaker overall snowpack BLT and at all elevations this is on top of weak basal facets.

Avalanche Summary

Natural cycle continues in the forecast area with numerous slab avalanches reported today on all aspects in the elevation range of 1900 to 2600m. Of particular note is a size 3 on Kitchener Shoulder, SE aspect at 2400ms running to ground.

The weather pattern is stable
