Summary
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
Problems
Loose Dry
Isolated to steep terrain where surface snow doesn't show signs of previous wind affect.
Minimize exposure to terrain traps where the consequences of an avalanche could be serious.
Aspects: All aspects.
Elevations: All elevations.

Expected Size
Deep Persistent Slabs
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.
Be cautious in shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
Elevations: All elevations.
