Check for stubborn windslabs lingering below ridgelines or in steep, exposed terrain.

A few size 1 to 2 wind slab avalanches were reported around White Pass on Monday and significant wind transport was observed through the week. Small dry loose avalanches were also seen around Haines Pass.

On Wednesday, sun and warm temperatures produced a natural wet loose cycle on steep solar slopes.

Wind has redistributed recent snow, forming pressed surfaces and wind slabs in open terrain while leaving 15-30 cm of soft snow in sheltered areas. A crust covers most solar slopes.

A buried surface hoar or crust layer, 40 to 60 cm deep, is variable in distribution and has produced some test results but no recent avalanches. Similarly, a December crust with facets, 100 to 150 cm deep on all aspects up to 1750 m, has shown no recent activity or significant test results.

Snow depth ranges from 100 cm at highway elevations to over 300 cm in the alpine.

Friday night

Clear. 20 to 40 km/h northeast wind. Treeline temperature -12 °C.

Saturday

Sunny with incoming cloud. 10 to 30 km/h southwest wind. Treeline temperature -3 °C.

Sunday

Mostly cloudy with isolated flurries, up to 5 cm of snow. 40 to 55 km/h southwest wind. Treeline temperature -2 °C.

Monday

Cloudy. 15 to 25 km/h southwest wind. Treeline temperature -2 °C.

• Wind slabs are isolated, but may remain reactive.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
