I just posted a video on my youtube channel that I took last night. It was about 9pm when some weather blew in and the "sounded" the "sirens." They were actually fairly loud but the tone is really lame. The siren closest to my house is about .4 miles due south. I was facing the siren at that location when I took the video. Actually it's only the 2nd time I have heard our ATIs since they were installed.
