Travel and Terrain Advice
- Be alert to conditions that change with elevation and time of day.
- The new snow will need time to settle and stabilize.
- Avoid all avalanche terrain during periods of heavy loading from new snow, wind, or rain.
Avalanche Problem 2: Cornices
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Large amounts of recent new snow and high winds are creating rapid cornice growth.
Travel and Terrain Advice
- Falling cornices may trigger large avalanches on the slopes below.
- Give cornices a wide berth when travelling on or below ridges.
Avalanche Summary
No new avalanches have been reported in this region on Friday. However, a natural avalanche cycle is expected to begin Saturday with the incoming storm.
Snowpack Summary
15-25cm of new snow is being redistributed by strong southwesterly ridgetop winds creating fresh storm slabs reactive to human triggers. Below the most recent storm snow there is a crust at treeline and below. The reactivity of the new storm slabs is likely to vary greatly depending on elevation/ temperature and orientation to wind. In general, I would expect the touchiest conditions to exist in exposed, higher elevation terrain.
Weather Forecast
SUNDAY: 40-60 mm of rain (snow above roughly 1500m) / Strong to extreme southwesterly ridgetop winds / Freezing level rapidly rising to around 1800m.
MONDAY: 60-80 mm of rain (snow above roughly 1500m) / Strong to extreme southwesterly ridgetop winds / Freezing level around 1800m.
TUESDAY: 10-15 cm of new snow / Moderate southwesterly ridgetop winds / Freezing level dropping to around 800m.
