HONOLULU (HawaiiNewsNow) - The state's monthly test of its outdoor siren warning system is scheduled for Thursday at 11:45 a.m.
According to officials, the siren test is a steady one-minute tone on all sirens. It is used to alert the public of any emergency that may pose a threat to life and property. Officials say the Emergency Alert System can also be used for terrorist incidents or acts of war.
Residents on Oahu near Campbell Industrial Park, Honokai Hale, Makakilo, Kapolei Regional Park, Kapolei Golf Course, and the Coast Guard Station at Kalaeloa, may also hear a "whooping" tone after the siren test.
The "whooping" tone is a test of the Hazardous Materials Incident outdoor siren warning group that will be activated if and when a HAZMAT incident occurs.
