@marcomarques The boundaries are given by the model provider - DWD. You would have to ask them. We are planning to add global ICON as well. Meanwhile, use ECMWF or GFS to see forecast for the islands.

@idefix37 Thanks for the report, difficulties with watermark removal. The borders are still visible in the postprocessed radar image. I have disabled this source for now, it should be fine since surrounding countries covers Belgium just fine.

@ubugnu Exactly, this single radar is part of our Spanish composite and has been out of order for the past few days: http://www.aemet.es/es/eltiempo/observacion/radar?w=1&p=am it is most likely temporary and hopefully will be online soon, this happens from time to time in Spanish radar source.

@Tomber42 Of course ! I have exchanged a couple of emails with Oleksii already. He did a lot of hard work to cover such a huge area and is always very helpful. Plus his API is easy to use. Hopefully next client version will display credit for Rainviewer.com (like Blitzortung.org for example).
We still prefer our own handling of radar sources, especially raw data, but it's a huge amount of work. So Rainviewer at this moment covers the additional countries that were added in the past 2 weeks. Our original cover that has been here since last summer hasn't changed (USA + most of Europe).

@csabatatar Oh boy, thanks for mentioning me in the comment. Now that I can see precipitation in the image, I see that the problem is not different range. The map projection is wrong. Note that the precipitation "clouds" are the same, but the scale is wrong (the island is way bigger on the Windy image). I already contacted Rainviewer.com , its creator Oleksii usually responds and fixes these minor problems quickly. It will be fixed soon. Thanks for the post !

@idefix37 Hello ! We use AROME with resolution 0.01° (1.3km). Both of the AROME resolutions have 00, 06, 12 and 18 ref time runs. There are also 03, 09, 15 and 21 ref time runs which we don't process. Advantage of AROME 0.025° (2.5km) is that it includes pressure-level layers. AROME 0.01° provides only surface-level layers, only wind and relative humidity are additionally in 20m, 50m and 100m altitude. However, AROME 0.025° also covers much smaller area - a square that covers whole France and a bit of surrounding area.

@Tomber42 It's still updated in 5 minute intervals ;-) nothing changed there. However, it takes around 10 minutes for the data to be displayed in the client (e.g. data that correspond to Germany precipitation at 14:00 are usually displayed around 14:10). I'll ask around whether there is a possibility to speed up this delay. The 20 minutes delay you experienced earlier was some kind of server hiccup. Usually it should be around 10 mins.

@Tomber42 Thanks ! It's already fixed in new upcoming version (I checked it on our test server). Soon !

@ivo Also quite frequent:

For clickable URL, use [TEXT](http://some.url)

It seems that the http:// prefix is mandatory, keep that in mind ! Or simply, test the result in the "Preview" first when creating the post !

@m-stankiewicz Ah, yes, you are right :/ the detailed forecast supports only 3 hour steps, even for ICON-EU.
Currently, the only way to view 1 hour steps for ICON-EU is like this:

1. Select required layer on a map (e.g., wind, temperature, etc)
2. Select ICON-EU model
3. Select required point on the map, for which you want forecast
4. Move the horizontal slider slowly to make 1 hour steps and check the values displayed on the selected point.
   Or as alternative which is probably much more easy - click Left or Right arrows on your keyboard to make 1 hour steps (if you had ECMWF model on, the keys presses would trigger 3 hour steps)

@fr-kiko I agree, it took me some time to learn the meanings of all things Windy offers too ! Simply because I am not a pilot, sailor, kiter, or someone who often looks for a very specific weather conditions. Take your time and discover all the layers slowly. If you don't understand some technical terms or layers, google it and look for wikipedia articles (maybe some time in the future, we will add our own descriptions, but for now we can only refer to external sources). Slowly over time, you'll start to understand all the displayed data and layers !
Also, handling the application itself and understanding all buttons, sliders and icons can be daunting at first ! But then, when you get accustomed to the applications all its corners, it becomes crystal clear ! Maybe one day we add some "first launch interactive tutorial", but that too is in "future plans" at the moment.

@meteo-gr Yes, exactly ! Fog and Thunderstorms layers are derived from global ICON's weather interpretation (WW).

• Fog data can have only three values (no fog; fog = 45; fog depositing rime = 48).
• Thunderstorms data can have only three values (no storm; storm = 95; thunderstorm = 96)

As stated in this table from DWD:

@sharingtacos it's in the far right in the detailed forecast:

On smaller displays (e.g. mobile), you might have to swipe left a bit to reach that information.

@meteo-gr We had something similar in testing version, although much more simplified (just pixels of different colors). Not sure why @ivo decided to use only fog and thunderstorm WWs as separate layers. I think we first want to check how accurate these data are, then maybe consider the rest.

I like this approach with "little warning icons" over the map very much !!

@gkikas-lgpz Hello ! Yes exactly :) here I talked about it to a more detail here: https://community.windy.com/topic/5458/thunderstorms-forecast-suggestion/5 .
However, ECMWF now also supports similar forecast for lightnings density (https://www.ecmwf.int/en/about/media-centre/news/2018/ifs-upgrade-improves-extended-range-weather-forecasts) which we plan to implement as well. So soon, there will be more options !

@idefix37 Oh man, I really love the overlay transition when changing the forecast time (in the video). The arrow rotations are super smooth and as a result - it gives you a clearer idea of the wind development over time.
On Windy when we change forecast time, there is a slight glitch when it re-renders the whole overlay and recreates the particles and isobars. I dream of smooth transition between forecast times on our page too, but I am not sure if it is possible to smoothly change the existing particles/isobars (especially performance-wise). I guess it's a trade for beautiful animations.

@idefix37 Yes, they are included in the UK radar we have from metoffice, but the images are in 15 minute intervals, and are usually delayed by another 15 minutes :/ not the best data source. This is also the reason why UK radar in our animation is usually displayed as too much behind (with the "crosshatch" pattern) in the last ~10 minute interval of the animation.

@tomber42 Actually, super interesting and very important ! We have to update our code accordingly to keep providing ICON after 01.10.2018. Thanks for the notification !

@beardedcook Hello. No, the light gray circles show our current coverage and range, nothing beyond that is available unless we find other radar source that supports larger radius.
