GOES East Satellite

Something looks odd in the current loop.

Look just to the west of southern Florida in the Gulf. There are two areas of convection right next to each other.

Then there are what appear to be blast waves spreading out towards trhe south and east.

Any ideas? It just looks odd to me. It may be absolutely normal but I am no meteorologist.
