Weather Forecast
Warm overnight temperatures and high freezing levels are forecast for the next 2 days. Before noon on Saturday, heavy snowfall will begin in the Icefields area with accumulations up to 25cm. This new precipitation will arrive with strong, gusty winds, and cooler temperatures. Warming and clearing should follow the storm on Sunday.
Snowpack Summary
The primary concerns for the snowpack are: 1. Isothermal conditions, especially on solar aspects, 2. Deep persistent weaknesses at the base of the snowpack, and 3. Windslabs in lee Alpine and treeline features. The well settled upper snowpack layers, especially at higher elevations, are bridging lower weaknesses for now.
Avalanche Summary
New avalanche activity is small & restricted to steep solar slopes usually near rocky terrain. Additional inputs of energy from rain, strong solar radiation, & poor refreezing temperatures overnight will exacerbate this problem. Windslabs could be triggered by skiers, and these smaller avalanches could trigger the basal weakness.

Intensity of incoming weather systems is uncertain on Saturday
