Weather Forecast

Monday: flurries with trace amounts of snow / moderate ridgetop winds from the northwest / treeline temperatures around -8. Tuesday: sunny / moderate ridgetop winds from the northwest / treeline temperatures around -10. Wednesday: light flurries / moderate southwest winds / treeline temperatures around -5.

Avalanche Summary

This region currently lacks regular observers, so no recent avalanche activity has been reported. Recent snow has likely formed storm slabs, but there is no information about potential deeper instabilities.

Snowpack Summary

The Cariboos received new snow on Saturday with up to 30 cm around Blue River and 10-15 cm in the northern parts of the region. Up to a metre of new snow has accumulated over the past week, likely forming touchy storm slabs on steep terrain and wind-loaded features. Also, sustained moderate winds from the northwest will likely develop wind slabs in the upcoming days. A widespread rain crust exists in the mid-snowpack, but the bonding of the snow to this crust is uncertain. Also, the presence of other deeper weak layers is uncertain due to limited observations. Treeline snowpack depths are 140-170 cm in the southern parts of the region and likely lower to the north. The most recent storm brought fresh snow to valley bottom.

Problems

Storm Slabs

An icon showing Storm Slabs
30-50 cm of recent snowfall will form touchy storm slabs in steep terrain and on wind-loaded features.
If triggered the storm slabs may step down to deeper layers resulting in large avalanches.Use caution in lee areas in the alpine and treeline. Recent storm snow has formed touchy slabs.
