Avalanche Forecast
Regions: Corner Brook, Gros Morne, Long Range Mountains, Northern Peninsula.
Use caution on north and east aspects in the alpine where new wind slabs could be found
Warming and rain on Monday and Tuesday will likely trigger a natural avalanche cycle
Confidence
High
Avalanche Summary
One size 2, natural, wind slab avalanche was reported on Saturday in the Trout River Bowl. Check out the MIN for more details.
Snowpack Summary
The snowpack is highly variable; on exposed west aspects very little snow remains, on exposed north and east aspects new wind slabs could be found. These wind slabs will overlie a firm and supportive crust.
In sheltered terrain  at 500 m the snowpack is 100 to 130 cm deep. The mid and lower snowpack is strong and bonded.
Check out this MIN from the Tablelands for more info.
On Monday freezing levels will likely spike far above the hills. The snow surface will become wet on all aspects and elevations. Significant snowpack loss could occur.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Seek out sheltered terrain where new snow hasn't been affected by wind.
- Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
- Use extra caution for areas that are experiencing rapidly warming temperatures for the first time.
- The first few hours of rain will likely be the most dangerous period.
Avalanche Problems
Wind Slabs
Rider triggerable wind slabs will likely be found in exposed terrain.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 1.5
Cornices
Keep your head up and look for cornices, they could fail during periods of strong solar. Cornices are a hazard on their own but can also trigger wind slabs on the slopes below.
Aspects: North, North East, East, North West.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2
Loose Wet
Rain and warm temperatures will likely trigger widespread wet loose avalanches on Monday. Avoid avalanche terrain during this time.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Very Likely
Expected Size: 1 - 2
