Spirograph!
Good day everyone,
Wilma definitely is developing an outer eyewall. If you see on the visible loop, a "dark" area wobbles on the opposite side of the "pinhole" eye and is always across from the eye, like if it is connected by an imaginary line and rotating about a midpoint on that line.
I wonder if this is a mesovortex of some sort, developing in the "moat" between the outer and inner eyewalls and causing the wobble as both go around.
The wobbles are amazing, like your old "spirograph" toy with the colored pens ... Along a curving line with a hyper-cycloid / cardiod type pattern.
I wonder, just for argument's sake, if we assumed the eye passed over Cozumel, Mexico when this was happening ... Would the eye be able to "loop" around and hit the island again?
The "moat" region also shows on the visible floater (space between the inner and developing outer eyewall) with the inner wall forming a raised circular disk (with the "pinhole" in its center). I am curious whay will happen after the eyewall replacement is complete - Still have concentric eyewalls and their repleacement cycles, or maybe even an annular hurricane with a larger single eyewall?
This is just incredible.
