Heavy rain and extreme winds are forecast to continue; anticipate loose wet avalanche activity at all elevations.
Rain at lower elevations continues to melt and weaken the snowpack. While unlikely, the potential remains for wet slabs to fail in isolated areas.
On Friday the field team reported seeing numerous small loose wet avalanches in the Mt. Arrowsmith area. For more details check out their MIN.
With the current warm and very wet conditions hitting the Island we suspect a natural avalanche cycle is ongoing.
Rain has saturated the snowpack right to mountaintop elevations.
In the mid-snowpack, a crust/facet combination may exist in high alpine terrain.
The potential remains for wet slabs to be triggered on this crust in isolated areas.
Otherwise, the mid and lower snowpack contains a series of old crusts and is currently well-bonded and strong.
