Are you in the affected storm area? How did your winter tires perform?
Today was pretty rough, a local girl was killed so they closed the main highway here, called the Queen Elizabeth Way. The roads were more ice than slush. There was a definite base of ice then the slushy junk on top. The temps here hovered around the freezing mark all day.
My winter tires are Walmart Weathertech, made by Nexen and are 175R65-14. I had no problems going anywhere including up some very steep grades travelling up the Niagara Escarpment. My traction control hardly came on at all, only when I floored it just to see.
