Northwest Inland

Assess for storm slabs and unstable snow before committing to steep or high-consequence terrain.

Friday: There were reports of small (size 1) skier-triggered avalanches on north facing treeline slopes in the Hankin-Evelyn area.

Wednesday: Several small natural and rider-triggered wind slab avalanches were observed in the mountains northeast of Hazelton.

Field data has been limited. If you head to the backcountry please consider submitting your observations to the MIN.

At treeline elevations and below, the upper snowpack is moist or wet due to warm temperatures and rain.

Storm snow amounts over the last week have varied across the region. The current storm slab is 15-20 cm thick and is made up of heavy, dense, and in some cases moist or wet snow. On north and east faces these slabs may be thicker due to recent winds. The storm snow may be poorly bonded to a crust formed in early January that extends up to treeline elevations.

Two deeper surface hoar layers exist. These layers have become dormant and unlikely to trigger.

• Loose avalanches may start small but they can grow and push you into dangerous terrain.
• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
