Weather Forecast

Forecasts are showing a clearing trend over the day Saturday. Overall it does show a slow cooling trend but the sun is packing a bigger punch these days and will likely wake up the snowpack!

Snowpack Summary

Continuing moderate to strong SW winds in the Icefields area. These are perfect transport speeds, combined with a heavier moist snowpack and a steady input of rain or wet snow has created dangerous soft slab conditions through the forecast area. This slab is sitting over multiple touchy interfaces on all aspects and elevations.

Avalanche Summary

Numerous soft slab and storm slab avalanches have been observed in the forecast region up to size 3. Avalanche control at roadside produced results to size 1 on heavily controlled slopes.

Confidence

Timing or intensity of solar radiation is uncertain on Saturday
