As fast as the water came up in Boone on Wednesday, it began to recede, but not before firefighters had to make nearly a dozen rescues.
Eyewitness News was with firefighters as they pulled one person after another from the rising water in Boone.
Brianna Carter ended up in the back of an ambulance after her car was swept off a roadway and she ended up in the chilly water.
"My car started floating and I tried to put on the brakes but by then it was too late. And then the water started coming in my car," Carter said.
Firefighters also scrambled to get people living near a propane leak to safety. Firefighters showed where the leak was spraying gas. Nearby, they helped a woman whose apartment was surrounded by rising water get out.
"It is real strong. It is real strong. I can't even breath well," neighbor Andrew Ovido said.
Firefighters said as the water began to recede they were able to cut off the spewing gas. Several of the people who were rescued said the water began to rise after it got dark and they didn't realize what they were driving into.
Firefighters said it will be Thursday before they can assess all the damage from the flash flooding.
