Wind speed should be three digits

The wind speed on the screen only shows two digits. In tracking hurricane Ida towards the center it’s showing 28 mph or 28 kn whatever the case is. I’m thinking you only programmed it for two digits.

Nothing abnormal here I think; if you change the level to say, 850 hpa, you can see wind speed values > 100 Knots.
About Surface level, see image below (which explains itself - at least I hope so); wind speed values:
- near Zorro in the very center of the hurricane (bottom) and grows up further (here up to 70 knots, upper on image)
- in knots: 3 digits is rare; hurricane starts at 64+ knots on Beaufort scale
- in km/h: 3 digits often happens (e.g. Ida in image is now 101 km/h)
- in knots on Beaufort scale on upper right side of image
In addition, you must consider that
In the center (the eye) of a hurricane the wind is weak or nul. So 28 kt is just correct.
stronger winds are at some distance of the center. Currently the ECMWF model is predicting 70 kt max, which is much lower than the 130 kt reported sustained wind. The reason is not because Windy uses only 2 digits for wind speed. It is due to the fact that global models are not good at predicting the 1-minute sustained winds.
try to display Gusts instead of Wind, you’ll see that Windy can show wind speed with 3 digits in kt.
