  Thanks, I just read though the other reports of it. If this is not a bug, it is at least a suboptimal design. Surely you would not want this to happen if it could be avoided. I never know what the actual value is and thus cannot fully trust the map reading other than to give a sort of estimate. It does sound like it is due to some sort of averaging over an area. I guess the point value for that location is not readily available. I will also say in Windy's defense that in practice it probably doesn't make any difference. Surely the error bars on most of the forecasted values are as large or larger than the variability while zooming. It just offends my engineering sense of precision.

  Hello, Yes it's a storm now! But a it's a very small one at least. Its convection area is very small and thunderstorms appear to be quite small compared to other typical tropical storms. However at this moment thunderstorms tops are reaching FL450. That represents a lot of water that could surely cause flash floods and mudslides... Satellite imagery showing the size of the storm and thunderstorm tops People from Guadeloupe to Grenada should be extremely careful regarding floodings, wind gusts and also waves caused by this little storm. AROME wind accumulation for the next 42 hours, showing gusts up to 130 km/h And ahah yes I didn't notice that about island names :)

  @karamell As far as I know the base map is from mapy.cz with additional data from Open Street Map. You can use these maps with Windy Maps app for outdoors activities: https://windymaps.com/app/

  [I am aware that this is a very old post, but it is still being searched and viewed, so I think it is important to correct some incorrect information presented here] @TheRadarGuy "The data is from NASA's GEOS-5 satellite." GEOS-5 is not a satellite. It is a computer-based global atmospheric modeling system, maintained by NASA's Goddard research facility. https://gmao.gsfc.nasa.gov/GEOS_systems/ GEOS-5 can generate SO2 (and other chemical) data by a kind of simulation (called 'reanalysis') from computed estimates of SO2 concentrations, which are initialized and then consistently updated by interpolating satellite and meteorological observations (e.g. winds) using the GEOS-5 atmospheric circulation model to make geospatial 'forecasts' of SO2 concentrations between actual observations. https://acd-ext.gsfc.nasa.gov/People/Colarco/Mission_Support/ There are several satellites which carry SO2 sensors and can be used to initialize and update the GEOS-5 forecasts: https://so2.gsfc.nasa.gov/ NASA's AURA OMI (Ozone Measuring Instrument) which has been in operation for more than a decade. https://www.atmos-chem-phys.net/16/4605/2016/ ESA's Copernicus Sentinel-5P TROPOMI (Tropospheric Monitoring Instrument) https://developers.google.com/earth-engine/datasets/catalog/COPERNICUS_S5P_NRTI_L3_SO2

  @tomhudu As you probably know the shape of waves, in a given place, is a mix of different kind of waves: The windsea (also called wind waves) is produced by the local wind. The main swell is produced by a strong wind far away. Secondary swells are produced also by winds far away but in other places. All of them have different heights, come from different directions and show different periodes (which is the time between 2 wave crests) Swell 1 is the main swell, swell 2 and 3 are secondary swells (the swell classification 1, 2, 3 depends on their respective height). See also: https://community.windy.com/topic/3361/description-of-weather-overlays For example close to NewZealand coast you can observe different swell trains due to several storms at this season. In this example, main swell is E-W and Swell 2 is S-N caused by 2 different storms.

  I would not think so, as the NWS needs radars that are even more advanced than this. Thanks for replying @Yeah-Boi

  I'm a contractor in the US, weather dictates what I do day to day, sometimes hour to hour. I have searched forever to find a full screen radar page that loads fast with no clutter and and no ads all over the place. I also use a start page on my browser and this can be embedded into that page and is always current with out a refresh. When I click on the link itself that I have set my area to, it loads right away, no waiting. As for local forcast, I use weather.com, but their radar is horrid and loads slow. WIndy load time is less that 1 second for every test I have run. They do have some errors that could be sorted but that is for IE, Safari, and a few Android versions. Imo This is by far the absolute best out there. Granted I mainly use the radar, but I like the fact that I can also see real time lightning strikes and wind direction and speeds. As far as ease of use, for me it is quite straightforward. The sidebar to set the layers I want to use is a plus. But for others it might be somewhat confusing.
