The southernmost wave has gotten a little better organised overnight, and if it was a bit further north it would probably have a good chance for development. However, as Alex said, it is about to slam into South America, so don't expect anything big.

BTW, looks like another huge wave is about to exit the African coast. Check out this image - plenty of storms across the continent moving towards the Atlantic. On a lesser note, it also shows the intense low-pressure system that will move across the UK through today and tomorrow:-

The waves of tomorrow?
