Spring is in the air.

Pack your sun screen and you shades, and dial back your terrain selection on solar aspects during the heat of the day.

    The March sun has some punch, and may trigger loose snow avalanches on solar aspects during the heat of the day.

    Storm slabs buried a mix of surfaces; firm windslabs in all open terrain, sun crust on steep solar aspects below treeline, and small surface hoar and facets in sheltered areas.

Avalanche Summary

Friday: Field teams observed a few size 1-1.5 loose snow avalanches triggered by the sun on steep slopes. There was similar activity in the highway corridor.

Thursday: A field team triggered a size 1.5 storm slab on a NE aspect at treeline, and there was a MIN report of an avalanche involvement on the Dome exit.

Snowpack Summary

Fluctuating temps have settled the upper snowpack & created a surface crust below 1500m (higher on solars).

Up to 45cm of snowfall early in the week, with warm temps and a brief wind spike, created storm slabs over the Feb 26th interface - wind effect in open areas, small surface hoar and facets in sheltered terrain, and sun crust on steep solars.
