The Guam Homeland Security and the Office of Civil Defense will conduct a test of the all hazards alert warning system, AHAWS, sirens on Tuesday 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 60 seconds of the โalertโ siren tone. The Sept. 9 siren test is separate from the pre-scheduled monthly tests and is being conducted to assess operations and identify any operational issues. Future tests of the AHAWS sirens will be conducted on a monthly basis, in conjunction with Naval Base Guam and Andersen Air Force Base, and will typically fall on the first Tuesday of each month, unless it falls on an observed holiday.
