Weather Forecast

A prolonged period of strong southwest flow from the Pacific will last through the middle of next week. The next pulse of moist air will arrive on Sunday and should bring 10 to 20cm of snow to upper elevations of the forecast region. A break in the weather on Monday and another pulse on Tuesday that could deliver 20 to 30 mm of precipitation.  Freezing levels are forecast to rise beginning late Saturday ad continue to rise to 2200m on Tuesday

Avalanche Summary

Recent reports of a number of size 1.5 natural-cornice failures have been reported through the region.

Snowpack Summary

The snowpack varies widely across the forecast region. The Duffey Lake area has received the most snow as well as the most rain during the recent storms, and also experienced the highest freezing levels. The Coquihalla has a shallower snowpack with slightly cooler temperatures. Storm slabs of varying depths are developing above a mixture of old surfaces left behind after the recent  high pressure.  We have not had many observations from this region but generally warm temperatures should contribute to a well settled snowpack, if you are out in the mountains please submit your observations to the Mountain Information Network.
