It's possible, but not likely for two storms that formed out in the same region of the central/eastern Atlantic. The time between them would need to be just a day or two, despite the different paths, and it's not likely for that to occur.

You could have one such storm (moving north of the Caribbean) plus a Gulf storm potentially impact the US at the same time, or one such storm (moving through the Caribbean) plus a system that develops south of Bermuda threaten the US, but this scenario is less likely due to the nature of the environment that the latter such storms tend to form in (and ultimate direction that they travel).
