The monthly test of the all-hazard Statewide Outdoor Warning Siren System, coordinated with the test of the live audio broadcast segment of the Emergency Alert System, is scheduled to take place at 11:45am on Thursday, September 1.

During the test, all Statewide Outdoor Warning Sirens will sound a one-minute Attention Alert Signal (SteadyTone) while the live audio broadcast segment of the Emergency Alert System is conducted simultaneously.

There will be no exercise or drill accompanying the test.

The all-hazard Outdoor Siren Warning System for Public Safety is one part of Hawaiʻi’s Statewide Alert & Warning System used to notify the public during emergencies. If the siren tone is heard in circumstances other than a test, the public is encouraged to follow emergency information and instructions provided by official government channels which may be in the form of a local radio, television station broadcast, and/or a cellular Wireless Emergency Alert.

Wireless Emergency Alert delivers sound-and-text warnings to compatible mobile cellular phones. The Emergency Alert System & Wireless Emergency Alert’s notifications are managed by the Federal Emergency Management Agency’s Integrated Public Alert and Warning System, the nation’s alert and warning infrastructure.

Emergency management and disaster preparedness information is located at the front section of telephone directories in all counties.
