I'm not sure about this, but I believe it was at the end of The Emerald City of Oz that Dorothy moved to Oz full-time, bringing with her, of course, her Uncle Henry, Aunt Em, Toto and Billina the chicken. Uncle Henry was ailing by then, and it was basically the only way to save his life. A lot more convenient for Dorothy, too, whose back-and-forth travels usually involved a natural disaster of some kind: Cyclone, storm at sea, earthquake, what have you. Apparently the only way over (or under) the Deadly Desert and into Oz is if you're blown there by a typhoon.
And thereby hangs a nice metaphor, I think: life is frequently tempestuous, but sometimes a storm can push you in the right direction, so that when the weather clears up and you can see the world around you again, you find that you've arrived in a Better Place, charged with energy. So -- although it's dramatic, this isn't necessarily a purely negative card, by any means.
I think this may be one of my favorite-ish cards. I like the way the wind blows through it and swirls up those circular objects. At the top left we have a barometer (pointing to "stormy" no less!); below that we have a swirly, globey vintage marble, a travel sticker, and in the lower left a vintage astrolabe, "an instrument ... used to make astronomical measurements, typically of the altitudes of celestial bodies, and in navigation for calculating latitude." Astrolabes, orrerys... I like all that kind of old gimcrackery....
