Monthly outdoor siren warning system tested Monday

The Department of Emergency Management will conducted its monthly Outdoor Siren Warning System on Monday.

The test occurred at 11:45 a.m. During an actual emergency these broadcasts will be heard at frequent intervals and may become continuous if need be.

Residents in areas surrounding Campbell Industrial Park, Honokai Hale, Makakilo, Kapolei Regional Park, Kapolei Golf Course, and the Coast Guard Station at Kalaeloa may have heard a “whooping” tone following the siren test. The “whooping” tone was a test of the Hazardous Materials Incident outdoor siren warning group that will be activated in the event of a HAZMAT incident.

If the siren in your community did not sound or did not operate properly, please call the Department of Emergency Management at (808)723-8960 to report it. You can also email the department at
