CHARLOTTE, N.C. — A series of thunderstorms moving across western North Carolina has triggered major flash flooding, inundating roads, apartments and parts of several counties.

The Charlotte Observer reports (http://bit.ly/1buP7OY ) that Hickory Mayor Rudy Wright is telling residents to stay indoors and away from flooded roads and washed-out bridges.

No injuries have been reported.

Parts of Catawba and surrounding counties were under water Saturday. Catawba County officials say some of the worst flash flooding in decades followed a nearly stationary weather system that dumped more than 12 inches of rain.

Several miles of Interstate 85 in Cabarrus County was closed for a short time Saturday due to high water.

It is at least the fourth major flash flooding event in the Charlotte region in the past month.
