Regions

South Coast.

This bulletin was produced using very limited field data.  We would love to hear your observations if you're get out in the hills at [email protected]

Confidence

Fair - Due to the number of field observations

Weather Forecast

A weak system will reach the coast Tuesday night bringing cooler temperatures and light precipitation to the Coast range.Monday: Mainly cloudy, no precipitation. Ridge top winds will be light from the southwest. Freezing levels to remain between 3000m in the Duffy to 3400m around the Coquihalla .Tuesday: Cloudy with sunny periods, no precipitation. Winds at ridge top will remain light from the southwest. Freezing levels falling to between 2000m and 2400m.Wednesday: Mainly cloudy with light flurries.  Ridge top winds will be light from the west. Freezing levels 1900m.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Information coming from this region has been extremely limited; however, reports suggest there is about 70cm of snow at 1600m in the Duffey Lake area and about 120cm at the same elevation on the Coquihalla. Terrain below treeline is reported to be mostly below threshold for avalanche activity.Steep solar aspects have seen a daily melt-freeze cycle with recent warming.The upper snowpack is settling with the recent warm temps and will have likely gained considerable strength.  A few crusts can be found deeper in the snowpack.  Some facets may be found lingering around these crusts at higher elevations. Observers are not identifying any of these as cause for concern at this time although they might be worth exploring.

Problems

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.
