Uncanny? Coincidence?

This is the kind of thing that keeps happening, and I find it quite scary.

I had been working on the Internet for school, and as I went to close the browser I found behind it this window open which was offering demos of free screensavers, and the one highlighted was a tornado at sea!

Is it a warning, or a clue, or simply a coincidence? It seems too uncanny to be a coincidence. I need to check with the others.
