Five observations from official hurricane landfall reports
The National Hurricane Center estimated 130-knot winds at Ian’s Cayo Costa landfall in September 2022. Its Fiona report gives about 75 knots at landfall in Puerto Rico. The National Weather Service reports 140 mph just before Helene’s Florida landfall in 2024.

Each point has its own local date, location and wind unit. Helene’s figure is for just before landfall.
One storm can have several landfalls
The NHC’s Ian record separates its Florida landfalls and the later landfall near Georgetown. Each point has its own time, place and estimated wind. Source 1
What sustained wind means in the reports
The figures describe sustained winds or estimated storm intensity. A measured gust at a weather station is a separate observation, with its own place and time. Source 1 Source 2
Use local time with care
The Helene event account puts Florida landfall late on 26 September in Eastern Daylight Time. The Ian and Fiona reports provide UTC timings for the listed events. Source 3 Source 1 Source 2
Why event registers keep the original unit
Ian and Fiona are quoted in knots by the hurricane centre. The local Helene summary uses miles per hour. Leaving those units visible makes it possible to reproduce the observations and helps avoid treating the numbers as though they were on one scale. Source 1 Source 2 Source 3
