Sea To Sky

Use caution in high alpine terrain, where fresh storm or wind slabs may exist.

No new avalanches were reported on Wednesday.

On Tuesday, numerous natural wet slab and wet loose avalanche activity were seen in treeline and below treeline terrain.

If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network

At treeline and above 10 to 20 cm of recent snow sits above a widespread crust and may show a poor bond. Below the crust is a layer of moist snow. The new snow tapers with elevation loss but the surface crust continues to exist below treeline. This crust should provide a bridge over any previous layers of concern deeper in the snowpack.

Thursday Night

Mostly cloudy with no precipitation, northwest alpine winds 30 to 40 km/h, treeline temperature -5 °C.

Friday

Sunny with no precipitation, northwest alpine winds 10 to 20 km/h, treeline temperature -7 °C.

Saturday

Mostly cloudy with 5 to 15 cm, south alpine winds 60 to 80 km/h, treeline temperature -7 °C.

Sunday

Cloudy with 5 to 15 cm, southwest alpine wind 20 to 40 km/h, treeline temperature -2 °C.

• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
• Avoid areas where the snow feels stiff and/or slabby.
• Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
