Warning: Wind chill expected to hit -20 in Mission tonight

It’s going to get really cold.

Environment Canada has issued an Arctic outflow warning for the Fraser Valley, including Mission.

According to the government website, strong outflow winds and cold wind chill values are expected or occurring.

An arctic ridge of high pressure over the BC interior will build southwards giving arctic outflow conditions. Wind chill values of minus 20 to minus 25 will persist over North Coast Inland sections through Tuesday.

In Whistler, Howe Sound, and the Fraser Valley, wind chill values of near minus 20 can be expected tonight and Tuesday morning.

Any outdoor activity exposes people to an increased risk of frostbite. If outside, dress warmly in layers and stay dry. Cover as much exposed skin as possible to avoid frostbite.

Be aware of the potential for falling branches or power lines.

The website goes on to say Arctic outflow warnings are issued when bitterly cold air flows from the interior to coastal communities and the outflow winds create wind chill values of -20 or less for six hours or more.
