Those are the pictures of the tops of the clouds where in the center of the basically flat surface you have the bowl where the eye is located. The central pressure has been dropping rapidly and the outer storm isn’t encountering any friction from wind [shear] or land. The storm is symmetrical which makes it easier to spin up.
A new eyewall will start forming eventually at about twice the radius of the current one as a result of the central air column cooling and dropping after it reaches altitude.
It has low shear, warm water, and constant guidance, so there’s no reason for it not to get stronger.
