Avalanche Forecast

Moderate

Wind slabs continue to be triggered throughout the region, to size 1.5. Check out this MIN from Mineral Lake, and this one from Knee Peak where riders triggered several wind slabs on south facing slopes.

A rider remote, size 1.5 slab avalanche was reported from Haines Pass, likely occurring on Wednesday. This avalanche highlights the spatial variability throughout the region, and need to use caution in areas where the snowpack is shallow. See MIN for details.

Exposed areas have variable, wind-affected surfaces, while sheltered terrain still holds pockets of soft snow. Wind slabs are likely found on many aspects due to recent northerly and southerly winds.

In eastern White Pass, an isolated surface hoar layer 30 to 50 cm deep remains reactive in tests.

A buried facet layer on a December crust (100 to 150 cm deep) is present up to 1750 m on all aspects, but hasn’t shown recent activity or significant test results.

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

Sunday Night

Partly cloudy. Winds switch from northwest to southwest and increase, 30 to 40 km/h.

Monday

Mostly cloudy with flurries bringing up to 2 cm of snowfall. 40 to 60 km/h southwest wind, with stronger gusts. Treeline temperature -12 °C.

Tuesday

Cloudy with light flurries, 1 to 5 cm of snow. 40 to 50 km/h southwest wind. Treeline temperature -8 °C.

Wednesday

Cloudy with 5 cm of snow. 40 to 50 km/h southeast wind. Treeline temperature -4 °C.

• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
• Make observations and continually assess conditions as you travel.
