Her eye is contracting down to a pin point, she's may hit Cat 4 before dawn. Apologies on this one, Ciel was right on the Category 3 today. Shows again and again how a hurricane can hit Major Cane status without the best of conditions in an only optimal environment.. once they get the engine going they can really spin up fast. Also, her center has been small the whole time and it is easier for a small storm to ramp up like this than a bigger one.

Amazing. Would say she can easily barrel through a high but you never know until you know so keep watching.

Inner eye going to go through Eye Wall Replacement Cycles sooner rather than later. And, she is barely moving it seems.
