Jan. 7. Don’t stress: The outdoor warning sirens around the McGuire Nuclear Station will be tested between 11 am and 1 pm on Wednesday, Jan.12. The 67 sirens within 10 miles of the power plant will sound for five to 30 seconds—maybe more than once.

Because it’s a test, local broadcasting stations will not interrupt regular programming to broadcast Emergency Alert System (EAS) messages. If there were ever a real emergency at the plant requiring the sirens to be sounded, local radio and television stations would broadcast information and instructions to the public.
