actually appears mostly below the cirrus deck. quite likely a gravity wave from somewhere as they can travel large distances. there is convection building in a outer band behind that wave so .. it is a wave of some sort. hard to tell
Could that be related to the steering flow that'll eventually push Irma to the southwest? It's showing up fairly well on WV.
