Regions: East Island, North Island, South Island, Vancouver Island, West Island.

More snow and wind is on the way. Lee areas are more likely to be rider-triggered.

If you're seeing greater than 20 cm of new snow, treat the danger as one step higher.

Avalanche Summary

On Sunday, there was a large storm slab (size 2) near Mt Beadnell which failed on the crust buried early March.

Also, numerous small, dry loose avalanches occurred during the storm.

Observations are limited, but it's suspected that natural avalanche activity has decreased while rider-triggering remains possible.

Snowpack Summary

40 to 120 cm of storm snow fell on Sunday. Storm snow came in with strong southwest wind which redistributed snow into deep pockets on lee slopes. Underneath is a thick crust except on high north facing terrain, where new snow buries 5 to 20 cm of dense snow overlying a crust from earlier in March.

The mid and lower snowpack is strong and dense.
