    On Sunday, rain will cause wet avalanches in steep terrain. Mostly small loose avalanches are expected, but some larger wet avalanches are possible.

    On Monday, a surface crust will form and stabilize the snowpack.

Confidence

Moderate

Avalanche Summary

Wind slabs formed over the past few days, but by Sunday morning the main problem will become wet loose avalanches caused by rain falling on dry snow.

Snowpack Summary

Wet surfaces are expected with Sunday's rain, which will form a rain crust when temperatures cool on Monday.

20 to 50 cm of recent snow sits above a widespread crust layer. Strong southerly winds have scoured windward slopes and formed deeper deposits on lee terrain features.

Many parts of the region have low snow coverage and lower elevation terrain is likely thin and rocky.

Weather Summary

Saturday Night

Storm approaching with 3 to 8 cm of snow. 40 km/h south wind. Mountain temperatures -5 °C.

Sunday

Snow switching to freezing rain and then rain in the morning with up to 30 mm in the south and 10 mm in the north. 100 km/h south wind. Mountain temperatures reach +4 °C as freezing levels climb to 2000 m.

Monday

Mix of sun and cloud. 20 km/h northwest wind. Mountain temperatures drop to -8 °C.

Tuesday

Mix of sun and cloud. 20 km/h northeast wind. Mountain temperatures -3 °C.

Terrain and Travel Advice

  • Minimize exposure during periods of heavy loading from rain.
  • Loose avalanches may start small but they can grow and push you into dangerous terrain.
  • Avoid steep convex slopes.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
