    Many lee and cross loaded features  have a soft slab condition. With the rising temperatures we expected to se continued natural avalanche occurrences.

Weather Forecast

Wind and warming temperatures are expected through the weekend. Snow accumulations near the Columbia Icefield area may reach 10 cm by Saturday.

Snowpack Summary

A thin snowpack has been redistributed by recent winds. Observations from the roadside indicate there is a rain crust or temperature crust in the low alpine on north and east aspects. This has created a sliding surface for recent snows.

Avalanche Summary

Several  natural slabs avalanches have been observed along the Icefield Parkway.  Some of these are big (to size 3) and have propagated over hundreds of meters.

Confidence

Due to the quality of field observations
