Monthly Siren and Emergency Alert System Test, July 1
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 for Thursday, July 1 at 11:45 a.m.
During this monthly test, all Statewide Outdoor Warning Sirens will sound a one-minute Attention Alert Signal (SteadyTone). A simultaneous test of the Live Audio Broadcast segment of the Emergency Alert System is conducted with the monthly siren sounding, in cooperation with Hawaiʻi’s broadcast industry. 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 you hear this siren tone in circumstances other than a test, follow emergency information and instructions provided by official government channels. This may be in the form of a local radio, television station broadcast, and-or 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 FEMA’s Integrated Public Alert and Warning System, the nation’s alert and warning infrastructure.
O’ahu residents in areas surrounding Campbell Industrial Park may also hear a “whooping” tone following the siren test. These areas include portions of Kalaeloa, Makakilo, Nānākuli, Kapolei, and ‘Ewa Beach. The “whooping” tone is a test of the Hazardous Materials (HAZMAT) siren warning group that will be activated in the event of an actual HAZMAT incident requiring emergency notification of businesses, schools, and residents within the vicinity of Campbell Industrial Park. Contact the City and County of Honolulu Department of Emergency Management at (808) 723-8960 for more information on the HAZMAT warning group siren test.
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:
