Oklahoma Tornedo

T. Uranus was square to T. Pluto exactly.

Exact, exact.

But I still don't entirely get it. 

Altho Uranus can be 'anything goes' and out of the blue, and these two big planets coming together is not an everyday event...other than it's suddenness, the wind ingredient in a tornedo would--to me--correspond with some Mercury aspect--even Mercury to Jupiter, in addition to the Uranus/Pluto connection.

Mercury was one degree away from Vulcanus--the force.  But a whole degree away.

And from my understanding of the physical earth attributes of Pluto, the event would include something deep, which a tornedo doesn't.

So I'll read some other blogs and see if they have any explanation for the astrological correspondence--apart from the Uranus/Pluto square.
