Avalanche Forecast

Issued: Mar 28th, 2019 4:58PM

The alpine rating is moderate, the treeline rating is low, and the below treeline rating is low. Known problems include Loose Wet.

ldreier, Avalanche Canada

South Coast Inland.

It is going to be a sunny day with a few clouds. Solar input will increase the potential for triggering loose wet avalanches.

Summary

Confidence

High - The weather pattern is stable

Weather Forecast

THURSDAY NIGHT: Few clouds, light northeast wind, alpine temperature -4 C, freezing level 1300 m FRIDAY: Mainly sunny, light northeast wind, alpine temperature -1 C, freezing level 2200 mSATURDAY: Mix of sun and cloud, light southerly wind, alpine temperature -1 C, freezing level 2200 mSUNDAY: Mix of sun and cloud, light southerly wind, alpine temperature -1 C, freezing level 2100 m

Avalanche Summary

In the north of the region on Wednesday several size 1 loose dry and wind slab avalanches were reported in the alpine and at treeline on north and west aspects. On Tuesday a natural size 2 loose wet avalanche and a skier triggered size 1 wind slab avalanche on a northerly aspect were reported. On Monday loose wet avalanche activity up to size 2 was reported on solar aspects.

Snowpack Summary

Up to 15 cm of recent snow at upper elevations is bonding well with a variety of snow layers underneath, but there might still be isolated wind slab which can be triggered by humans. On higher north aspects above 2000 m it may sit on some dry, faceted snow. At most other places the new snow is sitting on either moist snow or a crust.

Problems

Loose Wet

The snow surface will weaken with increasing air temperatures and solar input during the day and increase the likelihood of thin loose wet avalanches running in steep terrain, especially on those slopes facing the sun.

Minimize exposure when the solar radiation is strong, especially if snow is moist or wet.Cornices become weak with daytime heating, travel early on exposed slopes.Use caution above cliffs and terrain traps where small avalanches may have severe consequences.

Aspects: East, South East, South, South West, West.
