Regions

Northwest Inland.

This bulletin was produced with very little field data. Significant snowpack variation is likely to exist. Please send your observations to [email protected].

Confidence

Poor - Due to the number of field observations

Weather Forecast

Monday: Inland areas could see an inversion, with freezing levels rising to 2000m. The winds are forecasted to be light to moderate from the south, broken skies and staying mostly dry.Tuesday: Increasing clouds in the afternoon and chance of light precipitation. Freezing levels decreasing to 1500m. Winds moderate from the southwest.Outlook for Wednesday: A zonal flow will hit the coast and spread inland. Light to moderate precipitation and light/moderate southwest winds. Freezing level hovering around 700m.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

The few reports we have received suggest there is little snow across the region. One operator is reporting 50cms of snow at 1100m. The region has seen its fair share of wind in the past week and spatial variability in snow depth likely exists. By and large, most of the region is below threshold except for where the wind may have re-distributed snow into pockets of wind slabs. Keep in mind these pockets of snow that may be enticing to ride are the same slopes that may be the most likely to slide. If you are looking for more information, refer to the Northwest Coastal Bulletin for an idea of what may be happening in some of the deeper snowpack parts of the region.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
