Ewa Beach residents were surprised to hear outdoor warning sirens go off around 2 p.m. Saturday.
The sirens were turned off by police and a spokesperson for the Hawaii Emergency Management Agency said its control center is checking on what set off the sirens. According to computer systems, it was not triggered by a break-in.
Technicians are scheduled to go into the field Monday to find out the cause.
Since there was no emergency behind the sirens going off, no information was sent to the news media. If there was an emergency, however, information from HI-EMA would’ve been sent out.
