Low Alpine: Below 1000m
Description:
So there's plenty of windslab lying over a touchy weak layer on shady aspects, as well as the potential for more " ordinary" wind or storm slab avalanching on other slopes subject to snow loading.Time to take it easy.... Some large avalanches could run right out to valley floor over the next few days so travel up under the runouts of major paths on or near the divide is not recommended.

Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
It looks like most of the low elevation wet slides have done their thing already but you never know ... do you ? If things warm up and we get rain on top of the new snow thats fallen above 1800m more wet slides will result.

Recent Avalanche Activity

Recent Avalanche Activity
Numerous small loose wet slides below about 1700m. observed from the village. Many slab avalanches to size 2 1900 to 2100m visible up the Hooker valley. Debris from paths up Hayter stm reached the Hooker lake

Current Snowpack Conditions

Current Snowpack Conditions
20 to 50 cms of snow has fallen near the divide above 1900m in the last 24 hrs with rain below about 1700m. The amount of new snow tapers off with elevation and distance east of the divide. Strong NW winds have redistributed the new snow and heavy deposits of windslab will lie on lee slopes. Storm snow instabilities are likely to exist within the new snow but the main area of concern is on shady slopes where the new snow and windslab now lies over a rain crust topped with a weak layer of facetted snow.

Mountain Weather

Mountain Weather
Cloud and precip eased off during the day, fine breaks out east but socked in all day on the divide. More rain, snow, and wind on the way.
