HONOLULU (HawaiiNewsNow) - In addition to the regular monthly test of the outdoor emergency siren on Tuesday, the state will also be conducting its attack warning siren test for the second time.
This is what you'll hear: A one-minute steady tone followed by a one-minute wailing tone, which is the sound you'd hear should an attack happen.
The test, conducted by the Hawaii Emergency Management Agency, will take place at 11:45 a.m.
Earlier, the Department of Emergency Management reported a siren malfunction in Kahala at around 8:15 a.m., but officials said there was no emergency. Technicians are investigating.
The attack warning siren test was initiated in response to rising tensions with North Korea and its threat of a nuclear attack.
The state said that in December, 28 of its 386 sirens played the wrong sound or had other technical issues. Some people in Waikiki said they couldn't hear the sirens very well.
