Tornado

Right after the scene where the fruit bats are roosting we cut to everyone in the land rover (this happens shortly after Osborne is killed), Mike London is driving and in the back ground there is a dust cloud in the back ground that looks suspiciously like a tornado on the ground. You will probably have to pause rewind a few times but its definitely there.

I know it looks like the sun is out, but since many tornadoes happen at the end of a storm, it is not uncommon for the sun to be shining in the background.
