I received an email from one of my coworkers who has family members that are being sent home due to the dangerous driving conditions on highway 63. Below is a section of the email from someone who has been on the highway today and was forced to stop south of Lac Labiche due to the conditions.
Travel is not recommended under any circumstances, visibility is at best a few hundred meters and drops to 0 meeting vehicles. In the first 30 km from the junction of 55 heading north there are two head-on collisions both involving more than one tractor trailer and multiple passenger vehicles with wreckage strewn for several hundred meters in one of them and a half-ton that is in 5 pieces.
So please, PLEASE drive very carefully if you must venture to 63! - this weather is not conducive to travel so if at all possible I would suggest putting off any driving.
