Holes in the sky?

Do you have any ideas what this is? What made these holes in the clouds? It looks really cool, though!

Almost a tornado?

 

I took this photo in Monteverde, Costa Rica, it was the second of two photos. The first one was ruined since the flash was on. The tube was even further down then. I thought it looked a bit like a tornado, it was a very peculiar cloud nonetheless. It turned out to be a phenomenon caused by cold air pushing downwards or something.
