The warning sirens are used to alert the public to emergencies.

During this monthly test, all warning sirens will sound a one-minute Attention Alert Signal (Steady Tone). There will be no exercise or drill accompanying the test.

The Attention Alert Signal informs residents to turn on a radio or television for information and instruction for an impending emergency, or if in a coastal inundation area, evacuate to higher ground.

The outdoor warning sirens are one part of a three-component emergency notification system. A simultaneous test of the Emergency Alert System is conducted with the siren system, in cooperation with Hawaii’s broadcast industry. In the event of a real emergency, warning sirens and Emergency Alert Broadcasts would be joined by alerts via the Wireless Emergency Alert system, which delivers sound-and-text warnings to mobile telephones and compatible devices.

Emergency management and disaster preparedness information is located at the front section of telephone directories in all counties. The public may contact emergency management and county civil defense agencies to report siren operation issues:
