It would be great if we could set up an alert for when forecast lightning flash density or CAPE exceeds a certain value of our choosing at a location.

I’d imagine it wouldn’t take too much time to add this capability since it would just be using the same technique as the existing alerts we already use for other parameters such as wind speed, temperature, etc…. except it would just sample the gridpoint value of forecast lightning flash density or CAPE.

Even better would be if such an alert could be triggered when a combination of both lightning (or CAPE) and 500hpa wind speeds (a proxy for shear) exceeds a certain threshold. This could provide a useful heads up on the potential for severe thunderstorms.

@Ondřej-Šutera Ah thanks very much for that! The sounding option doesn't appear for me at first unless I scroll to the right in that section so that's why I didn't see it at first.

@Suty said in animation feature removal:

@ccarawan @Nezolikesrain Possibility of creating your own animation was removed because of high number of bugs there and low usage of this feature on the end of users.

@Suty have you seen all the animations that were still uploaded every single day to https://community.windy.com/topic/8191/your-animations/36468 by the sheer number of people who were still using that feature?

That includes myself. Not sure how that could classify as low usage. Nor the statement that there were a lot of bugs. I only experienced one single issue but was able to work around it.

Even to this day, I personally don't know of any model website that had an animation feature to this standard so it's very disappointing that this has been taken away. Especially considering some of us are premium users paying a fee.

EDIT: I just noticed many other people have also reported the same problem in another part of the Windy threads, but thought it'd be good to post about it in this Bugs report section as well.

A major glitch has suddenly appeared with the wind accumulation layer in both the desktop and mobile versions of Windy.

It's displaying huge areas of unrealistically high values and it quickly gets far worse the further you look ahead in time. In fact, after several days lead time, it covers the whole world with values well over 1000 km/hr !

It seems like it's incrementally adding the wind gust values for each forecast timestep onto the values of the previous timestep instead of finding the maximum value within a given time period.

I've tried logging out and the problem still occurs.

Thanks very much to the Windy team for recently adding ACCESS-C to the list of models for Australia in the desktop version, but can you please extend the 18z runs of ACCESS-C out to its full 42 hours rather than just 36 hours?

The 00z, 06z, and 12z runs only go out to 36 hours but the 18z run was increased to 42 hours a few years ago as a result of forecaster feedback.

Adding precipitation types such as rain vs snow vs freezing rain (perhaps using colour-coding) to work out where snow would be more likely than rain would be great!

Not sure whether this is a bug or it's been intentionally left out but I'll post this question in here just in case it is a bug.

Just wondering where has the ability to long-press on any point on the map to view a model forecast sounding gone after the latest UI update to the app?

@korina oh and sorry, one more suggestion before I forget. Not sure if this deserves a separate thread but it would also be extremely useful if there was an optional setting where alerts extend out to 7 or 10 days.

I know accuracy is lower at that type of range but if it was available as an option that could be turned on or off by premium or more advanced users (while keeping the default alerts to 5 days unless the user forces a change) and adding a disclaimer that skill will be lower, I think it would be a great addition.

I'm a premium subscriber and I'm also unable to use the right arrow key to step forward through the forecast timesteps in the desktop version of Windy.

This occurs in both the Microsoft Edge and Chrome web browsers.

One of my friends who's a premium subscriber is also having the same problem in Chrome.

P.S. Using the left arrow key to step back through time also reveals a bug where it steps back using excessively coarse time intervals e.g. 3 hour increments in the hourly ECMWF forecast with forecast times (those times don't even match up with the model's 03, 06z, 09z, etc times either).

@Korina thanks very much 😁

@kubav027 thank you!

A couple of problems have been occurring with the 18z runs of the ACCESS-C model for Australia.

Firstly, as at time of writing this (2210z Tue), ACCESS-C BN covering the Brisbane domain has not updated since the 06z run whereas it should be displaying the 18z run by now. It's two runs old now.

Secondly, a longer-standing issue is still continuing where the 18z runs of all the ACCESS-C domains are still only going out to 36 hours instead of their full forecast period of 42 hours.

I'm pretty sure there was a brief period of time when I saw them go out to 42 hours, but the 36 hour limit issue has come back again.

I first reported this issue back in 2024 (https://community.windy.com/topic/37768/please-extend-18z-access-c-out-to-its-full-42hrs/) so I was hoping that it would have been fixed by now.

@Stewie2023gamin said in wind accumulation weather picker never showing data:

this may be a bug, refreshed the browser multiple times and opened different tabs, and it said each time “data not available for this location”, this happens no matter where i place the picker

I'm experiencing the same problem too.

Can you please make the vertical demarcation lines at midnight that separate each day from one another in the meteograms much easier to see? (in their current form, they're almost impossible to see - refer to attached screenshot)

It would also be helpful if the day name/date could be moved to the centre of each 24hr period to improve readability instead of being situated near the start of each day.

@Gkikas-LGPZ said in Alerts for forecast lightning/CAPE:

I think convective rain, lightning and/or thunderstorms layer
Is a better indicator.
CAPE, by itself, is not a good indicator
as I describe here
https://community.windy.com/post/26433

@gkikas-lgpz yeah I know (I'm a meteorologist by trade) but while convective rainfall often works well for standard "wet" thunderstorms, it's not as good for dry high-based storms that occur in arid to semi-arid interior areas, especially in the country I live in.

Even ECMWF lightning flash density has a consistent tendency to somewhat underestimate dry inland storms in my country but overall, its skill is good.

In any case, I only mentioned CAPE as a potential alternative if lightning flash density is somehow impractical to implement for alerts (but I still prefer lightning flash density as the parameter to be used for alerts).

This is another feature request I posted on here a few years ago, but thought it would be good to post again because it's a very useful feature that many weather websites have had for a long time now, but Windy doesn't:

Would it be possible to add the ability to view the early forecast data from model runs that are still in progress, without having to wait until the entire run is finished?

Taking the ECMWF model for example, the forecasts from the 00z runs usually don't become available at all in Windy until after 08z.
In contrast, the 00z forecasts from incomplete runs still in progress start becoming viewable on many other websites from as early as about 0530z and the entire forecast is commonly available by around 07z.

This delay also affects other models.

Not sure if this has already been reported before but whenever I load up Windy forecasts for layers such as rain/thunder, wind speeds, etc, only the default colour scale/key for that layer appears in the bottom right of the map rather than my saved customised colour scales.

However, my customised colours do display properly on the map itself.

Attached is an example for the rain/thunder key showing the discrepancy:

I initially posted this on here 5 years ago and was advised that it would be considered, but didn't hear any more about it. I know not all ideas can be implemented, but I think it would be great if we had such a feature considering thunderstorms are an important weather hazard. So I'll post it again on here in the hope that it gets more traction:

*" It would be great if we could set up an alert for when forecast lightning flash density or CAPE exceeds a certain value for one of our alert locations.

I imagine it wouldn’t take too much time to add this capability since it would just be using the same technique as the existing alerts we already use for other parameters such as wind speed, temperature, etc…. except it would just sample the gridpoint value of forecast lightning flash density or CAPE.

Even better would be if such an alert could be triggered when a combination of both lightning (or CAPE) and 500hpa wind speeds (a proxy for shear) exceeds a certain threshold. This could provide a useful heads up on the potential for severe thunderstorms. "*

I'm experiencing the same problems with the desktop version as well, and for all models.
