In sintesi

Use caution in wind affected terrain.

The storm on Tuesday will likely form larger and more reactive slabs in steep lee features.

    Currently, Small wind slabs are expected on east and south aspects.

    The storm forecasted to hit the hills on Tuesday will likely form larger and more reactive slabs on westerly aspects.

    New snow and wind can weaken cornices.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.
  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

No recent avalanches have been reported. thank you to everyone who filled out a Mountain Information Network report this week.

Snowpack Summary

10 to 20 cm of recent snow could overlie a thin crust in sheltered features, a layer of surface hoar may also exist at this interface. Ridge tops are expected to be scoured back to this crust on north and west aspects, while cornices and deep pockets of wind deposited snow are expected on south and east facing slopes.

Several other thin crusts could exist in the upper snowpack, but they are not currently a concern. The remainder of the snowpack is well settled and bonded. Snowpack depth in the hills ranges from 110 to 150 cm in sheltered terrain.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Strong wind is building wind slabs farther downslope than usual.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
