Confidence
Moderate
Avalanche Summary
No new avalanches have been reported since last weekend.
Snowpack Summary
The top 20 cm of the snowpack is soft and loose. The exception may be in Gros Morne, where feathery surface hoar crystals were found over a thin rain crust on Friday.
Previously soft snow may be redistributed into deeper and stiffer deposits in leeward terrain. With moderate winds shifting from north to southwest and back again, expect to find lightly wind-affected surfaces on most aspects on Sunday.
Verify conditions through the week, an incoming storm could make this picture look a lot different.
The mid and lower snowpack are generally dense and strong.

Terrain and Travel Advice
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
- Wind slabs are most reactive during their formation.
- Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
Avalanche Problems
Wind Slabs
Small pockets of wind slab may avalanche under the weight of a human on Sunday. With more snow expected on Monday and Tuesday, expect blowing snow to start creating larger and more dangerous slabs in wind-loaded terrain.
Aspects: North, North East, East, South East, South, South West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 1.5
