Just before the rain...

When it rains here in Ouaga, it rains hard; but just before the rain something different happens. Pictured above are three shots taken in about the same spot. I had to move a little on the last two due to all the dust. If you look closely at the second shot, you can see the dust moving towards the camera. I I had taken a good panoramic shot, you would really be able to see just how much the dust looks like a huge wall. I will post another pic after this that will better illustrate that wall effect.
