Emergency Sirens

Test of Outdoor Emergency Warning System

On the first business day of the month at 11:45 am, the state of Hawaii conducts a test of its siren and emergency alert system. The warning sirens are used to notify the public of emergencies. During this test, all warning sirens sound a one-minute Attention Alert signal. This “steady tone” alert signals natural disasters such as a hurricane or tsunami event. If you hear this siren tone in circumstances other than a test, listen to local TV and radio for emergency information and instructions. You can learn more about Hawaii’s statewide warning notification system on the Hawaii Emergency Management website.
