Should I be worried?

I thought they had taken down all sirens years ago. Apparently there is still at least one. It's signaling something. Sadly, nobody knows what it means.
Could be anything. "Duck and cover" as well as "We're conducting the decennial check up."

As the world still seems to exist, I'll now try once more to find out how to safe the new PoA trailer. For some reason the QuickTime link refuses to work and WinMedia Player doesn't like me.
[ETA: Woohoo. Working link for QuickTime at HPANA]
