DALLAS (CBSDFW.COM)- A severe thunderstorm that brought several inches of rain left dozens of drivers stranded.

At Baylor Hospital, several drivers who had parked in the basement level of the parking garage went to their cars in the middle of the storm, only to find they were nowhere to be seen.

“It’s a lake, it’s not a parking lot!” said Lea Munden, who was visiting her husband in the hospital. Her F-150 truck and several more vehicles were underneath several feet of water.

Heavy downpours caused flash flooding, which overloaded the drainage system.

Several feet of water subsequently gushed into the bottom floor of the Baylor Hospital parking garage.

Dakota Andrew had dropped his mother off at the hospital and had rushed to find parking.

“I wasn’t expecting rain like this, so we figured we’d park down here and everything will be alright,” Andrew said.

Later, when he came back to his car to pick up his laptop, he noticed everything was flooded over.

His concern, “How I’m supposed to explain this to my insurance company.”

Others did not fare as badly. Latoya Jones scooped water out of her vehicle, but it is still salvageable. She’s only had it for 3 months.

Even Dallas Fire rescue needed some help today. Engine 17 stalled out on Hall Street near the hospital when high water reached the engine.

The water receded a short time later.
