Sometimes the snowpack is just so weak and slow to change, that you need to continually resist the temptation to step-out into more exciting terrain. This is one of those winters where patience is the most important skill you can have.
Summary
Weather Forecast
There is no new snow in the near-term weather forecast, as a ridge of high pressure remains stationary over the central rockies. Some cloud cover may appear, but no precipitation is expected and temperatures on Thursday will range from -5 to -10 and light NW winds.
Snowpack Summary
In many areas, the surface snow remain unaffected by wind and overlies a generally weak and facetted mid-pack and base - particularly in the Lake Louise area and on the east side of Hwy 93 north. Closer to the divide, the deeper snowpacks are stronger and more supportive. Surface hoar up to 10mm continues to grow on the snow surface.
Avalanche Summary
No new avalanches reported today in this region, but we did see a 24-hr old size 2.5 on Mt. Ogden in Little Yoho region (2600 m). Natural avalanche activity has abated, but we continue to feel that human triggering is likely.
Confidence
Problems
Deep Persistent Slabs
Because the snowpack is so weak, we don't trust any avalanche starting zones. Avoid steep areas where avalanches can start, and think carefully if you cross tracks or run out zones. Continued conservative choices will remain important for some time.
Be aware of thin areas that may propogate to deeper instabilites.
