The monthly test of the all-hazard Statewide Outdoor Warning Siren System is scheduled to take place today at 11:45 am. The siren test will be coordinated with a test of the Live Audio Broadcast segment of the Emergency Alert System. 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. 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. 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.
