    One large avalanche in neighboring Kananaskis was reported yesterday on this layer. Until it heats up it will remain as a low likelihood, high consequence avalanche problem.

Weather Forecast

Temperatures are forecasted to remain quite cool (near 0 degrees) in valley bottoms until Wednesday. By midweek expect there to be an increase in daytime warming and subsequent rising of the danger rating. A very light dusting of snow is also expected over the next few days, nothing substantial.

Snowpack Summary

A supportive crust exists on all aspects above 1900m. Isolated windslabs were reported in the high alpine (3000m) near ridges. Solar input on south aspect in the afternoon will break down the crust.

Avalanche Summary

No new avalanches were observed or reported today.

Confidence

Freezing levels are uncertain on Wednesday
