GHS/OCD to Conduct Routine Testing of Advanced Warning Systems

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) will conduct routine testing of the All Hazards Alert Warning System (AHAWS) sirens from seventeen locations on Tuesday, September 3, starting at 3:15 p.m.

Residents, visitors and motorists surrounding the AHAWS sirens can expect to hear pre-scripted voice messaging announcing the start and end of the test, and ten-seconds of the “Alert” tone, which can be heard here: Tones%20Wav%20Files/Alert.wav.
