Dead corpse? Nah, there wouldn't be any... They would probably be taken away by the river, unless the body got stuck on sticks, or underwater foliage. But firstly, why would there be a body? o.o
I would also like to say that I have a fear of tornados... I know every normal person would be scared of them, but when summer comes and when it's humid outside, I run to my window and look out for strange clouds. It's all because once there was a very strong rain in our city. Our trees that were about three meters high were touching the ground. After this, I saw a cloud. A tornado was slowly appearing, and my knees literally started to shake, my heart jumped in my throat, I started to shake like I was electrocuted.
LUCKILY, the wind took the tornado away from our house. Phew!
