Sea To Sky

The avalanche danger remains high in the alpine above the rain line. Loose wet avalanches may still be reactive to human triggers.

Moderate

• We are uncertain about how the snowpack will react to the forecast weather.
• We are uncertain about alpine conditions due to limited field observations.

Several slab and wet loose avalanches were reported since Monday, up to size 3.

If you are in the backcountry, please share your observations by posting a MIN.

Rain continues to saturate the upper snowpack up to 2100 m in some areas. Above the rain line, new snow combined with strong south to southwest winds is building slabs in lee terrain.

A widespread crust is buried 20 to 60 cm deep below 2100 m. Beneath this, the snowpack is generally well settled with no significant layers of concern.

Wednesday Night

Cloudy. 25 to 35 mm of rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2100 m.

Thursday

Cloudy. 20 to 25 mm of precipitation as snow or rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1800 m.

Friday

Cloudy. 30 to 45 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1800 m.

Saturday

Mostly sunny. 1 to 4 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -6 °C.

• Loose avalanches may start small, but they can grow and push you into dangerous terrain.
• Keep in mind that the high density of wet avalanches can make them destructive.
• Be alert to conditions that change with aspect and elevation.
