"It's called 'black ice' because it tends to look like the rest of the pavement on the road, although in reality, it's actually clear," the US Forest Service notes. "Black ice forms without creating bubbles, which allows it to blend in with any surface it forms over. Black ice is dangerous precisely because it's hard to detect."

Chief meteorologist Jonathan Novack, Sharron and Idolina are encouraging everyone to stay safe this morning as black ice coats local roadways. We're seeing a lot of accidents Wednesday morning with a lot of vehicles stuck on roadways in below-freezing temperatures.

Black ice is an invisible cold weather danger, but how does it form and how can you protect yourself when walking and driving?
