Summary
Weather Forecast
The Arctic air has arrived, and temp's have dropped. Today, sunny weather will dominate, with light northerly winds and no precipitation in the next 4-5 days. Temp inversions are expected to develop over the next couple of days, with alpine temp's warming considerably while the valleys remain cool.
Snowpack Summary
Reverse-loading from strong northerly winds yesterday has created wind slabs on southerly aspects. These slabs overlie a variety of surfaces, including suncrust on steep S-SW aspects, with 2-3mm surface hoar on most other aspects. Below this, the snowpack as a whole is strengthening. A weak basal layer exists on alpine N/NE aspects.
Avalanche Summary
A skier-triggered size 2 from a SW aspect, at ~2200m, was reported in the McGill area yesterday: 30cm deep, 40m across, running 200m in length. Numerous natural-triggered size 2 to 3 slabs were observed from steep alpine terrain yesterday. These occurred during the strong northerly wind event and pulled out of north and south aspects.
