Avalanche Forecast
Regions: Corner Brook, Gros Morne, Long Range Mountains, Northern Peninsula.
Rain will cause wet avalanches on Sunday and then a surface crust will form on Monday.
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.

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.
Avalanche Problems
Loose Wet
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.
Aspects: All aspects.
