Your knowledge of weather is far greater than mine. Any idea what the hurricane is going to do tomorrow? Do you think it is going to build up enough strengh to become a cat 4 again when it hits S.C./N.C., or wherever it hits?
Well where ever it hits again, it's going to do a loop-d-loop in the ocean first, Then likely hit the outerbanks, then, maybe it will hit New Jersey and then Cape code.
It will not go back to cat 4, probably not even to 3. It's moving very fast now and will continue to do so as it rides up the frontal/trough system situated along the East Coast.
It may get back up around 100-120mph before hitting land again. The windspeeds will be less, but the damage could still be great. When storms fly up the East Coast, they tend to pack quite a punch.
