Has the name Isaac been retired?
No. Isaac is on the 2030 list of Atlantic names, and it is not among the 100 names NHC lists as retired from the Atlantic (Tropical Cyclone Naming History and Retired Names).
When will Isaac be used again?
Isaac is next scheduled for 2030, when the 2030 list is used. The six lists rotate, so each one returns every six years.
A name on the list is used only if the season gets that far. Isaac is name 9 of 21, and 36 of the 46 Atlantic seasons from 1980 to 2025 got that far.
Why was the storm named Isaac?
Names go in alphabetical order, one per storm, as each storm reaches tropical-storm strength (39 mph, 34 knots), so a storm’s place in its season decides its name.
In each of 2024, 2018, 2012, 2006, 2000 and 1988, Isaac was the 9th name used in the Atlantic season.
