Regions

South Coast.

Recent rain has settled the snowpack, but still use caution during daytime warming. Continue to employ typical risk management strategies to enjoy a safe day in the mountains.

Avalanche Summary

No avalanche reports were available on Thursday, but it is expected that a loose wet avalanche cycle occurred during the storm.

If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!

Snowpack Summary

Over 60 mm of rain fell to the mountain tops on Thursday and Thursday night, saturating the snowpack. The snow surface may freeze into a melt-freeze crust overnight but should rapidly moisten during daytime warming, particularly on southerly aspects under clear skies. The snowpack is rapidly melting below treeline.

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.
