- Five- to 30-second quarterly test planned between 10 a.m. and 11 a.m.
- No public action required
SOUTHPORT, N.C. – Duke Energy and county officials will test the outdoor warning sirens around the Brunswick Nuclear Plant between 10 a.m. and 11 a.m. on Wednesday, July 1, 2026.
Why it matters: To ensure they are functioning properly, sirens will sound for five to 30 seconds. Anyone who hears a siren during scheduled testing does not need to take action.
- During testing, some sirens may be tested more than once. Follow-up testing after siren maintenance may be required after 11 a.m.
- Because this is a test, local broadcasting stations will not interrupt regular programming to broadcast Emergency Alert System (EAS) messages. If there was a real emergency requiring the sirens to be sounded, local radio and television stations would broadcast information to the public.
