Mark Herbison,
Another juicy storm is upon us and could bring up to 50cm within the next 24hrs.
Avoid avalanche terrain for the time being as the snowpack adjusts to the additional load.
It would be a good time to check out the recently opened ski resorts!
Summary
Weather Forecast
Snovember! Another moist storm system rolls in from the coast, delivering up to 50cm of snow through Saturday night and into Sunday evening. Winds will be 30-50km/hr from the South West and the freezing level could rise as high as 1900m.
There will be a slight lull in the weather on Monday, but Tuesday - Thursday could see up to 50-60cm.
Snowpack Summary
60cm of recent storm snow with 20-40km/hr South winds have built fresh slabs in the alpine. The mid and lower snowpack is generally rounded and well bonded. Below 1900m the November 15th crust exists in the mid-snowpack. Early season hazards have been freshly buried below 1700m, slide over the lumps and bumps with caution.
Avalanche Summary
Natural avalanche activity will increase over the next 24 hours as a significant storm pushes into the region. Avoid all avalanche terrain during this time period.
Friday saw a widespread avalanche cycle up to size 3.0 from steep, wind loaded terrain.
Confidence
Problems
Storm Slabs
Rapid snow loading will form fresh storms slabs. 20-50km/hr winds from the South West will also be building slabs in the alpine and exposed areas at tree line.
- The new snow will require several days to settle and stabilize.
- Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Loose Dry
As the new snow piles up, expect touchy loose dry avalanches in steeper terrain. These can be especially problematic in / above terrain traps
- Be careful of loose dry sluffing in steep, confined or exposed terrain.
- Avoid avalanche terrain during periods of heavy loading from new wind.
Aspects: All aspects.
Elevations: All elevations.
