    New storm slabs will be building with the incoming snow and winds. These will develop quickly with the warm temperatures.

Confidence

Fair - Timing of incoming weather systems is uncertain on Friday

Weather Forecast

A significant storm is approaching at this time.  Total snowfall over the next three days may be between 60-80cm with strong SW winds.  As usual, its just a forecast so we will have to wait till tomorrow and see how much new snow we get!  For now, Friday is calling for 20cm throughout the day and then the main pulse of the storm is expected on Friday evening and Saturday day.

Avalanche Summary

No new natural activity was observed on Thursday.

Snowpack Summary

Still not a whole pile of snow out there.  On average 50-70cm of snow can be found at treeline.  In Alpine areas strong winds on Thursday transported available snow onto lee aspects creating pockets of wind slabs.  Stiff windslabs should be expected in gullied terrain and along ridgelines.  Any avalanche that does occur is likely to involve the entire winters snowpack right now so keep the idea of a "rough" ride in your head.  Its still early season out there.
