Jasper.

Temperatures in Rome are rising, but the Swedish layer remains a serious concern for at least another two days.

Summary

Weather Forecast

Storm tapering a ridge of high pressure moves in and clear skies are starting on Monday.

Snowpack Summary

20 cm of new snow overlies a weak layer of surface hoar which was buried on February 23. Snowpack tests indicate easy, sudden planar results on this layer and we expect avalanches to occur easily, particulary on north aspects.

Avalanche Summary

Sunshine Village ski resort observed 2 size 3 avalanches on north facing slopes this afternoon.

Confidence

Due to the number and quality of field observations

Problems

Persistent Slabs

This problem dominates the region, particularly in the Bow Summit area and numerous avalanches have been observed.

Be aware of the potential for full depth avalanches due to weak layers at the base of the snowpack.Avoid travelling under cliffs that are exposed to sluffing from above.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

2 - 4

Loose Dry

Testing in Rome.

Be careful with wind loaded pockets while approaching and climbing ice routes.Avoid slopes with glide cracks.

Aspects: All aspects.

Elevations: Alpine.

Likelihood
