A lot is going to depend on the luck of upper-level wind shear.
My spouse the meteorologist says "diurnal heating".

Apparently the storm spins down overnight because of colder water and wind shear, but heats up during the day's sunshine despite the water's cooling effect. Then it spins down again at night. So instead of a steady glide slope down it's more of a roller-coaster oscillation along the dropping glide slope.

This morning there's no eye:

At "only" 90 MPH winds and a 15 MPH SOA it's moving a little faster, but I've read that picking the center of a storm without an eye is fairly difficult and controversial.

Live like you're dying, invest like you're immortal.
We grow old if we stop playing, but it's never too late to have a happy childhood.
Forget about who you were-- discover who you are.
