Emergency signal just a test Wednesday
On Wednesday, an emergency signal will interrupt TV and radio station broadcasts for about 30 seconds at 2 p.m.
Karyn Yaussy, the Catawba County Emergency Management coordinator, said the signal will only be a test and no action will be required.
Yaussy said the test is similar to regular emergency signal tests that air on radio and TV stations.
"The only difference is that every stations is doing it together on Wednesday afternoon," she said in an e-mail. "If it were a real emergency and you were to hear that emergency signal, it would be followed by some official instructions telling you where to listen for additional information about the emergency. In a real emergency, it is important to stop and listen for those local instructions."
