Why is Wind speed in hurricanes so wrong?

An article answering the question:
@Mekronid RU F'n Kidding me here!?!?! What a bunch of CRAP! That's like saying we here in Texas & Florida deserved Harvey and Irma!!!!
@julienmary Well Done! U made it sound solve able. Nearly maybe?
@meteo-GR I'm not sure the amount of resources reportedly correlating all of this data is as extensive as you believe. Just my opinion bro. Peace. Stay safe.
@conduit I am neither qualified nor remotely intelligent enough to appreciate your invitation to understand the math! Hee Hee. Cheers anyway.
@conduit It would be a good idea for someone knowledgeable about the mechanics behind this app to produce a Q&A page answering the most sought after questions/functionality
@cape I am in total agreement with you there. It's got loads of functions and looks great too. Pro version?
Hello, I'm in Sint-Maarten and I survived Irma (My house didn't). REAL wind values have been constantly updated, thanks to NOAA planes flying through the hurricane constantly. They are today the only way to give us real wind data during such storms (because instruments on the ground fly away). During the peak intensity just before Irma hits sint maarten, they measured 225 mph wind gusts in the eyewall of the hurricane, and sustained wind of 185 mph. We had an anemometer here in Grand-Case airport. the last wind gust measured by the instrument before it broke was 135 mph 2 hours before the eyewall. Everything is destroyed here.
Models like GFS and ECMWF cannot predict hurricane winds, especially close to the eye, where the wind is the strongest, because the resolution scale of these models is not wide enough (this is the main reason to me). In the front of the hurricane, there is northerly wind with strong updrafts, 7 kms away, in the eye there is no wind and a strong downdraft, and the 7km away there is a strong southerly wind with updrafts again ! All of that with huge changes in pressure. It's so powerful in a so small area ! That's why they created the Hurricane Weather Research and Forecasting model(HWRF). It is the only model using recon aircraft data, satellite imagery and buoys data at the same time !!! And it is the more precise model to predict hurricane wind direction and force (not the path of the hurricane).
So, regarding wind force and direction, the more you are close to the eye, the more GFS and ECMWF model will be inaccurate. But these models are better to predict the path of hurricanes, they work well on bigger scales !
@Siff I am questioning the reasons for the HUGE discrepancy between the supposed wind speeds proclaimed by "The Weather Channel",(150-165 mph), and those which are found on the "Windy" graph.
Something is not Kosher here.
Florida is Not being "whipped" by category 5 hurricane winds.
@georgewells The only possibility is a mix- up in kilometer/ mile usage .
That would make SOME sense of it.
Please see many other threads regarding this subject, including this recent one:
And the detailed discussion here:
Additionally, Windy does not create any forecast data but instead only visualises forecast and actual data received from various third party providers.
There are many useful but also complex and expert level tools and data available via Windy, therefore the user must always take care:
- To understand what information they are displaying and viewing
- To understand from where and when the information was sourced
- To understand what this information actually means.
Comparing Forecast data with Actual data can be a common mistake.
Around 1300 UTC on Monday 02 Sept the Windy Hurricane Tracker was reporting wind speeds of 142kn / 164mph / 264kph for Hurricane Dorian.
Hope this helps :)

Irrelevant if there is 200mph or 300mph, but it's really important if it's under 10, 20 or 40 knots...
