The 2020 Atlantic hurricane season finished with 30 total named storms — the most in any year on record — but three of those names will never be used again.
"There can be too much focus on the use of Greek alphabet names and not the actual impacts from the storm," the WMO stated in a press release. "This can greatly detract from the needed impact and safety messaging."
I feel this is more acceptable reason
"There is confusion with some Greek alphabet names when they are translated into other languages used within the Region. The pronunciation of several of the Greek letters (Zeta, Eta, Theta) are similar and occur in succession. In 2020, this resulted in storms with very similar sounding names occurring simultaneously, which led to messaging challenges rather than streamlined and clear communication."
