Emergency management, Duke Energy to test more sirens

Emergency warning sirens across the Carolinas will undergo additional testing Wednesday.

Duke Energy, in cooperation with emergency management officials in York, Gaston and Mecklenburg counties, will test a software upgrade on the sirens between 8 a.m. and 5 p.m., all within a ten-mile radius of the Catawba Nuclear Station.

The tests, which may occur more than once, will last about a minute.
