    Although the basal weakness (depth hoar) is generally dormant, with no recent natural loading of the snowpack, these may still be possible in isolated places.

Weather Forecast

Cold, clear and dry conditions as the arctic air rules supreme over our region.Thursday will be sunny with cloudy periods, alpine high -9 C, with an overnight low of -30 C, and light NE ridge winds.Mountain weather forecast available at Avalanche Canada.

Snowpack Summary

The upper snowpack on solar aspects could be stiffening up, otherwise remains faceted. Wind effect is visible in open terrain from previous SW switching to N winds. The Jan 18 layer (down 40cm) has faceted away in most places, but shows isolated sensitivity at treeline and below. The midpack is mainly supportive, over depth hoar in shallow areas.

Avalanche Summary

No avalanches were observed today. Some isolated whumpfs around treeline in the Whistler Creek area. No activity has been reported around the Icefields for several days.

Confidence

The weather pattern is stable
