Regions: South Coast.

For Monday, it is likely that the snowpack will have adjusted to recent snowfall and warming. Be on the lookout for the next big storm setting up for Tuesday!

Confidence

Moderate - The snowpack structure is generally well understood.

Weather Forecast

Sunday night: Cloudy, light south winds, alpine temperatures around 2 C with freezing level around 1900 m.

Monday: Cloudy, isolated wet flurries or light rain, light southwest winds, alpine high temperatures around 2 C with freezing level dropping to 1000 m.

Tuesday: Cloudy, 40-50 cm of snow above 1000 m, moderate southwest winds, alpine high temperatures near 0 C with freezing level around 1000 meters and rising to 1600 m overnight.

Wednesday: Mostly cloudy, 5-10 cm of snow, moderate west winds, alpine high temperatures near 0 C with freezing level dropping below 1000 m.

Avalanche Summary

No new avalanches have been reported in the region. 

Snowpack Summary

20-25 cm of snow fell over the weekend on a mix of crusts or old snow surfaces that have had time to adjust and bond.

Above 1200 meters, 50-100 cm of snow from last weekend comprises the upper snowpack. This storm snow is well settled with a strong bond to the previous surface. Below 1200 meters, the snowpack diminishes rapidly with elevation.

Terrain and Travel

  • Remember that the snowpack will be significantly different at higher elevations than lower down.

Avalanche Problems

Loose Wet

Above freezing temperatures and possible light rain at lower elevations may produce wet loose activity in the surface snow. These point releases are expected to be small but could have greater consequences in areas where terrain traps exist.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
