Will there be an increase in size of the storm over all size along with an increase in intensity
News sites in Florida now calling for a cat 4 at landfall.
Unknown. That’s storm-dependent... it’s a weird thing. Andrew as a Cat 5 was about as compact as you can get. Others are less intense, yet enormous in scope.
Right now, it’s hard to guess on Dorian until it gets it’s act fully together... which should happen within the next 24 hours or so.
Our experience with María: It was a very large hurricane with a very small compact eye. Just before landfall it went through an eyewall replacement cycle which weakened the storm a bit, but increased the areal exposure of the worst winds. So, we basically had a 35 mile-wide F3 tornado cross a 35 mile-wide island across the entire length of it.
