There have been several severe weather outbreaks in South America. Remember that for them this is there Spring season. Right now they are experiencing warmer moist air colliding with cool dry air. Just like the U.S. gets tornadoes in the Spring, so does South America.
As you watch the video you will notice that the tornado is actually spinning clockwise. In the U.S. most tornadoes spin counter-clockwise. While it is possible to get clockwise spinning storms in the U.S. it is more likely in the southern hemisphere. If you were to look at a radar image of this storm it would likely be a mirror opposite of a supercell in the U.S. The hook echo on this storm would be in the southeast quadrant, not the southwest quadrant.
