"The core is definitely struggling. It looks like some SW shear is impacting the storm, and it has not been able to recover from this morning's eyewall replacement cycle. Most likely scenario is the hurricane will fluctuate between 115 - 130 mph winds for the next day, then weaken to 100 - 110 mph (Cat 2) by Thursday night and Friday morning, when it will be very near the NC/SC coast."
