The Community Warning System (CWS) will be conducting its monthly siren test at 11am, Wednesday, January 1, 2014.

The CWS conducts a siren test on the first Wednesday of every month at 11am in which the sirens are sounded at full volume for 90-seconds.

Remember, it’s only a test.

Has anyone ever heard this siren? I have never. It’s news to me it exists.
