Well, considering that we've been facing 70km/h winds (gusting to almost 100km/h) here, and I read another member on this list is preparing for hurricane conditions, the temptation is to suggest: Windy.
Or more generally: Weather
Just a thought.
Maybe you could combine with Bookworm_Girl's idea and look for celebrations of weather? Or maybe solstice or equinox and so on.
I'm just getting carried away as I listen to our roof shake.
