In sintesi

Afternoon showers have the potential to destabilize the upper snowpack quickly, scale back your terrain use if it's raining.

    Rain and sleet at treeline will destabilize the snowpack. Expect natural activity if the rain continues.

Avalanche Summary

On Satruday, there were a few natural avalanches up to size 2.5 in the highway corridor. These were loose wet avalanches, triggered by convective showers and daytime warming.

On Friday there was a natural avalanche cycle triggered by rain & warm temps. This cycle produced avalanches up to size 3.5

There was a report on Thursday of a few skier triggered size 1's from the Herdman Couloir. MIN Report Here

Snowpack Summary

Heavy new snow with light to moderate wind has created fresh storm slabs. These slabs sit atop a series of crusts on all aspects except high north faces, where they overlie dry snow.

The Feb 3rd crust, down ~110cm, is the dominant mid-pack layer and still produces isolated planar results when tested.

With high freezing levels expect rain soaked snow at treeline and below. This will shrink our already dwindling snowpack at lower elevations.

Weather Summary

A low pressure system off the central coast continues to push stormy weather (with cooling temps) our way.

Tonight: Clear periods/ isolated flurries. Alpine low -4°C, Freezing Level (FZL) 1600m. Gusty moderate Southwest ridgetop winds.

Sun: Cloudy, flurries (up to 5cm). High -2°C, FZL 1900m. Gusty mod SW wind.

Mon: Cloudy. Low -8°C, High -5°C, FZL 1700m. Mod W wind.

Tues: Flurries. Low -8°C, High -3°C, FZL 1900m.

Terrain and Travel Advice

  • Avoid exposure to areas with overhead hazard during periods of rain.
  • Snow is accumulating at higher elevations despite lower elevations being almost snow free
