This satellite clearly shows a large vortex over the North Atlantic and the current storms off the African coast are connected to that vortex. The vortex moves by Coriolis, so as much as it moves daily may change the trajectory 'just that much' of the storms.
The vortexes are ionic and have influence on the storms connected to them. It is a 'single' dynamic. If the vortex migrates south that effects the direction of the storms and their path. If it migrates north or east that will effect it as well.
A few years ago there was a hurricane or two that continually slammed the North Carolina coast. It may have only been a TS. The point is the damage was considerable because the storm moved so slowly. That is the same 'wave dynamic' that exists with these series of storms. Instead of one slow moving storm there is a series of storms moving along the same path. This time there is more possibility of damage because these are not 'low velocity' storms and the continuous 'wave' of water will be stronger and more severe. The USA East Coast is not immune to this dynamic.
The North Carolina storm may have been Ophelia. It was a Cat One and was the same year as Katrina.
If the series of storm delivers the wave dynamics I expect there will be a lot more flooding accompanied by wind damage as well. The after math once the entire 'system' passes won't be this pretty.
