Winds are going to increase starting Wednesday morning. There is snow available to transport increasing the probability of overloading an already weak snowpack. Even more snow and stronger winds forecast for Friday.
Summary
Weather Forecast
In the Columbia Icefields, expect for Wednesday -10 to -16 degrees Celsius, flurries, and 25km/hr Westerly winds. Thursday and Friday winds will pick up Westerly 50km/hr Alpine and Treeline, trending warmer temperatures, and 15-25cm of snow Thursday night into Saturday. Still a few days away but one can hope and offer sacrifices to Ullr.
Snowpack Summary
A persistent slab at TL and ALP is buried by 10cm of snow and light winds making for powdery conditions. A rain crust is buried by this recent snow below 1900m. A somewhat dense upper snowpack overlies a weak faceted base making for unpredictably dangerous avalanche conditions. A surface hoar layer may be 40cm deep yet remains unconfirmed.
Avalanche Summary
Tuesday's patrol up Cavel road observed no new natural activity but this is only a small part of our region. Snowpack was extremely weak underfoot.
Confidence
Wind effect is extremely variable
