Monthly siren test coming Dec. 1
Sirens throughout Kaua‘i will sound for one minute this Thursday morning, during the Statewide Outdoor Warning Siren System’s latest monthly test.
The 11:45 a.m. Attention Alert Signal (SteadyTone) test will be coordinated with a test of the Live Audio Broadcast segment of Hawai‘i’s Emergency Alert System in cooperation with Hawai‘i’s broadcast industry, according to the Hawai‘i Emergency Management Agency.

There will be no exercise or drill accompanying the test, which will take place throughout the state. A map of Outdoor Warning Siren locations on Kaua‘i can be found here.
The all-hazard Outdoor Siren Warning System for Public Safety is the largest of its kind in the world, according to HI-EMA. It’s one part of Hawai‘i’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. These may be in the form of a local radio or 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. For the latest information from HI-EMA, or to sign up for county alerts, visit ready.hawaii.gov.
