Avalanche Forecast
Regions: Glacier.
Weather Forecast
Precipitation will ease off today with a short period of high pressure. Southerly winds will remain strong and freezing levels will rise to 1800m. A series of passing fronts will bring periods of light precipitation and gusting winds over the next couple of days. Freezing levels are expected to spike on Monday reaching 2200m.
Snowpack Summary
40cm of new snow in the past 24 hours. Expect significant loading on lee slopes from strong southerly winds overnight. The Jan 15 surface hoar is buried 80-100cm and recent snowpack stability tests indicate it is likely to be triggered and propagate. The Dec 17 surface hoar/ crust complex is down 130-180cm.
Avalanche Summary
We are currently experiencing a widespread natural avalanche cycle from 40cm of new snow in the past 24 hours and strong southerly winds. Numerous natural avalanches up to size 3 were observed in the highway corridor during the overnight period. Avalanches are likely propagating on the January 15 surface hoar down layer down 80-100cm.
Confidence
Freezing levels are uncertain
