In the Atlantic, Igor, Eta, and Floyd come into mind, and in the EPAC, Hector and Barbara come into mind.

Barbara '19: I don't think I've ever seen a better W ring in the Western Hemisphere. Eye temps got rather high too. Officially 135 kt, but if recon was able to get out that far, I wouldn't be surprised if they found 145 kt.

Hector '18: I believe there was recon data to support a Cat 5 upgrade, but it has remained at 135 kt.

Norman '18: Warm eye within a somewhat ragged W ring. Officially 130 kt, but maybe could've been 140-145 kt.

Hilary '11: Had a very small eye within a solid ring of deep CMG convection. Officially 125 kt, which seems low for a system with this appearance. Did recon ever go into it?

Other Cat 4s that I suspect could've been Cat 5s (but I am doubtful about) include Rosa '18, Fernanda '17 (another compact system), Seymour '16, Olaf '15, and Amanda '14.


Looking at the image, they do like low end Category 5 hurricanes at minimum. They have winds of 140 to 150 knots.
