With all the rain Chicago has had this week, a sinkhole forms in the south side and took three cars with it.

According to the Chicago Tribune, one person was taken to the hospital in serious to critical condition.

Witnesses said the hole opened up around 5am, quickly growing from about 20 feet to about 40 feet.

First two cars slid in, then a third as the hole widened.

A fourth vehicle was towed from the edge as it was about to fall inside. Watch where you park especially if it rains too hard.
