    Storm slabs are developing on all aspects and elevations. As the storm slab becomes thicker it is expected to consolidate and become more reactive to human triggers. Wind slabs may also continue to develop at higher elevations.

Confidence

Fair - Forecast snowfall amounts are uncertain on Tuesday

Weather Forecast

Overnight and Tuesday: Flurries are expected to continue overnight with little accumulation. Strong Northwest winds overnight are expected to become moderate Westerly as the next pulse of moisture moves into the region around mid-day.Wednesday:10-15 cms are forecast by late morning, becoming flurries in the afternoon.Thursday: Dry and cool as a ridge of high pressure moves into the region.

Avalanche Summary

Some soft slab avalanches up to size 2.0 have been reported in steep terrain.

Snowpack Summary

The recent storm slab continues to develop. Storm snow amounts are up to 30-40 cms. The storm snow has not consolidated into a cohesive slab, but we are expecting that to happen in the next 24-48 hours due to forecast new snow amounts. We expect the recent surface hoar and surface facets to be well preserved as they were buried by cold and dry new snow. The mid-pack is well settled, and deeply buried weak layers have not been reported to be reactive.
