Trans Canada Highway in B.C. both east and west of Revelstoke has been shut down due to dangerous avalanche conditions. A gust of warm air broke a number of temperature records in B.C. Wednesday which in turn drove an avalanche warning.
Temperature records at Vancouver International Airport broke after more than two decades when temperature reached 12 C. Squamish reached 10 degrees and Comox reached 12 C.
Meteorologist Mark Madryga said: “We’re getting a flow of air from just north of Hawaii, and as a result with the jet stream right over us we’re getting that mild Pacific air.”
Madryga says a series of storms is predicted to bring about 20 millimetres of rain each day for next few days. Temperature on Thursday was forecasted to reach 8 or 9 C, with rain.
Peter Marshall, a public avalanche forecaster at Canadian Avalanche Centre said: “It rained right up to the mountaintops last night (Tuesday) really heavily. It’s unusual because we had such a dry early December and now we’re in this wet and stormy period that’s causing the avalanche danger to shoot up rapidly.”
Avalanche risks are high for most of the province’s mountain regions. Snowstorms are likely to fall across southern B.C. on Friday.
