I think part of the problem for those venturing out tomorrow is getting to the river period. I had to do some work in Surrey today and just got back in to Chilliwack. My vehicle is covered in a sheet of ice, and looks like an ice ball. Whatever rain/wet snow is coming down is freezing and making the roads extremely slippery. If you do venture out tomorrow I would do so later in the day so the road crews can give the roads a good scraping, and hopefully they can lay down a bunch of salt and sand too. Without that you won't have much traction.
