CHARLOTTE, N.C. -- Roars of thunder shook homes across parts of the Carolinas Monday, while heavy rains soaked the ground beneath them.

In Catawba County, a possible tornado touched down.

“The wind picked up horribly and the rain starting circling like crazy,” said Katie Carmen.

“Power went out and about a minute later it was really loud and really quick, sounded like hail hitting,” Bryan Fletcher described.

They said it only took 10 to 15 seconds for the storm to do major damage.

“Trees down everywhere on the houses over there,” Fletcher said.

“We saw damage in every single yard,” Carmen went on.

Trees were uprooted and some were cracked in half. In Boone, flooding was the concern.

Photos were sent in of cars and SUVs nearly under water.

Back in Charlotte, winds whipped at a speed of 50 to 60 miles per hour. Trees toppled over outside of businesses and homes.

As of 10:15 p.m., over 500 people were still without power in Mecklenburg County, according to Duke Energy. In Gaston County, 137 were in the dark, with an additional 60 in Cabarrus County.
