@David-Polášek I mean, if it's targeted at a global audience, then you should use global language and refer to the region by name rather than something as vague as "The west coast".

@Ondřej-Šutera "this thread"? Was that intended to be a url? [edit] I guess you meant to link this.

When I open up Windy, there's a giant banner warning me about a hurricane about to hit "The West Coast". When I click it, it becomes more clear that it means "of North America" on the other side of the world.

My sympathies for those living there, I hope y'all will be fine. But when you say "The West Coast", the only way to know it's 9000KM away instead of 70KM, is to assume US Centrism.

If you want to convey world news, maybe try "barreling towards Baja California". If you want to alert people of dangerous weather, you should probably take a more local approach.

@korina Right, it does. But I hope you see why it would be more convenient to have that in map form as well. (Just like Wind speed and direction are also in the detailed forecast, but its nicely animated map view is still a useful feature)

Thanks for the suggestion @korina, I suppose I should've mentioned that one as well. Like the other accumulation layers it's too vague to be able to draw any conclusions. Any rain in a 3 hour frame results in a faint blue glow that's hard to distinguish. Both the tabular data and the radar data tend to line up more clearly with observed weather (especially temporally, looks like local radar has 2 minute temporal resolution), with the downside that the tabular data isn't on the map, and the radar data doesn't show any predictions.

Perhaps the accumulation map could be easier to read if it used a clear threshold to become visible, rather than fading out (I thought the precipitation type map could help, but it rarely seems to line up). But most of all I think it needs to have higher temporal resolution, and less smoothing to be at all helpful with answering the question: "Do I go outside now, or is it worth waiting a few minutes.". I realize you may be limited by available data, but I feel like you already have some of this data, just not visualized with the usual flair.

It would be nice to have a prediction of when it's going to start and stop raining, in the form of a map. In the Netherlands the website "buienradar.nl" is often used for this, but it doesn't let you choose the data sources, and isn't nearly as aesthetically pleasing as windy in my opinion. The feature looks similar to the weather radar feature in Windy, except it also shows the predicted continuation.

In Windy the predicted amount of rainfall is available in tabular form for one specific location, but it would be much nicer if this information could be scrolled through like the weather radar map. There's also the rain accumulation feature, but that tends to be too vague to get a solid idea of when the rain is expected. The weather radar feature gives an idea of the motion of the rain clouds, but it is currently left up to the user's imagination how the motion will continue, and tends to reset to the start exactly when you're at the part of interest (i.e.: the most recent data).

Both a map based visualization of the forecast, and an extrapolation of the radar data would be interesting to me.
