When you swig a barn door cross section thru those eye vortices, you see sublte pulses of precip spiraling inward on the radial.
At 90 degrees to the wind. Those vortices are the inward “exhaust” of much bigger jets...crossing from eyewall to eye, which isn’t spin to none. But the main pulse is in the eyewall..tbose,are just the keftovers.
