Weather Forecast

Thursday will be scattered flurries, 1-5cm, -11 degrees Celsius, and 10-25km/hr North winds. Friday will be sun and cloud, no precipitation, -20, and generally light Northerly winds. Saturday will be much the same as Friday except for some gusting Northerly winds at ridgetops. 

Snowpack Summary

Small amounts of new snow cover a variety of wind affected surfaces and rocks. Midpack layers are unreactive in field tests. Recent winds have formed some isolated pockets of windslab in exposed areas at upper elevations.

Avalanche Summary

No patrol occurred Wednesday and nothing reported. No natural activity observed by field team in Columbia Icefield Area on Tuesday. Minimal sloughing and very isolated pockets of soft slab triggered by ski cutting on Tuesday.
