Keep a heads up for areas where the wind has created a fresh slab

It may slide easily on the crust and may gain enough mass to push you off your intended line.




Avalanche Summary

There has been relatively few new avalanches observed in the last couple of days at Roger's Pass.

Over the weekend there was a natural avalanche cycle triggered by strong sun and high freezing levels. All observed avalanches were loose/wet and no bigger than size 2.5.

Snowpack Summary

10-20 cms of new snow covers a crust that exists everywhere but high north. Recent winds have blown the new snow into storm slabs in immediate lee features.

The Apr 8 crust is down ~30 cms, and was the layer responsible for recent remote & accidentally triggered avalanches. Feb 3rd crust is the dominant midpack layer down ~110cms and still produces isolated planer results when tested.

BTL the snowpack has gone through a number of melt freeze cycles and is in spring conditions.

Weather Summary

We'll see a clearing trend start on Wednesday as the cold front works out of the region and high pressure sets up over much of the province.

Tonight: Clear with cloudy periods. Nil precip, freezing level at valley bottom.

Wed: Sun and cloud, high -6°C, light northeast winds, FZL 1600m.

Thurs: Sun and cloud, Alp high -7°C, light northeast winds, FZL 1500m.

Fri: Cloudy with sunny periods, FZL 1800m
