Turns out the hurricane wasn't nearly as severe, at least not in my immediate area as the government and news were saying. But we're not out of the woods. As they begin cleanup, we may still lose power as they work on restoring it to others. That's happened before with lesser storms.
Well, the script should work. I tested it on a local mockup of the page. The only problem was that it wasn't as fast as I'd like. The best way to fix that would be to organize the page properly, with all the stylesheet links in the head followed immediately by the script tag.
But this version seems to speed things up a bit. It moves the links to the head:
