And it’s one thing to say it’s going to be hot, but when you see the effects of what heat can do, it really puts the situation into perspective.

It was so hot in Cape Girardeau, Missouri, on Sunday that roads began to buckle. The dramatic video shared by Albert Blackwell shows the moment the roadway snapped, sending a car flying through the air and slamming back onto the ground.

The extreme heat has also led to issues with travel. Amtrak implemented train speed restrictions on Monday from Washington, D.C. to Boston due to the high temperatures.

Washington FOX 5 reported an Amtrak train was evacuated after becoming stuck in a tunnel near Baltimore, which was forecast to experience a feels-like temperature of 112 degrees on Monday.
