It looks like a ghost tsunami hitting the buildings of Panama City, in Florida. JR Hott, a helicopter pilot, made these pictures and uploaded them to his facebook account, to an instant success. Actually, this kind of cloud tsunamis happen a couple of times a year, according to Hott, as the result of warm masses of air coming from the Gulf of Mexico. Below you can see some other images. The pics are beautiful but quite creepy at the same time, right?
