So it might weaken for a bit, but then the outer eyewall may replace the inner one and when that happens, it could re-intensify - correct?
Depends upon what happens and how fast. An eyewall replacement cycle tends to weaken winds a bit but also make for a much larger windfield. This close to the coast, it’s hard to tell if Matthew will have enough time to fully rebuild the outer eyewall.
The inner eye is actually drifting northwards within the outer eyewall, which is moving steadily NW, which is why some folks are claiming the system is starting to move north.
