Washington State will again be participating in the annual NOAA/National Weather Service Tsunami Warning Communications Test on September 15, 2010 at 10:15 a.m. For the first time as part of this annual test, the Washington State-Local Tsunami Workgroup has requested that Washington State Emergency Management Division activate the All Hazard Alert Broadcast (AHAB) sirens in the outer coastal counties to conduct a true ‘end-to-end’ test of the entire warning system.
The Workgroup, which is comprised of County/Tribal Emergency Managers as well as State and Federal agency representatives, has specifically recommended using the Standard TEST MESSAGE and Actual WARNING TONE as part of this test to help familiarize residents in at-risk coastal communities with the sound made by the sirens during an actual tsunami warning. This test will be different that the routine monthly testing that has been occurring on the first Monday of each month since it will broadcast an audible siren wail tone instead of a chime tone; however, the voice message will be exactly the same as the routine test message.
The standard test message relayed by the AHAB sirens is as follows:
"The following is a test of the siren system. It is only a test. This is a test of the siren warning system. If this had been a real emergency you should tune in to your local radio station or listen to this system for further instructions. This was only a test."
The regular monthly test conducted on the first Monday of every month will be unaffected by this statewide exercise.
