It's warm and wet out there!
There will be stormy weather and fluctuating freezing levels, which could mean rain on top of fresh snow. If that's the case expect ski/snowboard quality to decrease and the avalanche danger to increase.
Still getting out? Consider posting a MIN report!
Recent storms have deposited approximately 20cms of new heavy snow with moderate winds. This slab is especially reactive where its getting rained on!
Rain and sleet at treeline will destabilize the snowpack. Expect natural activity if the rain continues.
On Friday there was a natural avalanche cycle triggered by rain & warm temps. This cycle produced avalanches up to size 3.5
There was also a report of a few skier triggered size 1's from the Herdman Couloir. MIN Report Here
On Monday, a field team in the Fidelity zone was able to ski-control several dry/loose sz 1 avalanches on N aspects, as well as ski-cut a wind slab on an E aspect.
Heavy new snow with light to moderate wind has created 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.
A low pressure system is moving through the region, bringing stormy weather the next few days. There is uncertainty in the models about snow/rain amounts but most are showing steady precipitation & warm temps
