I suggest some modifications in french.

@jpomeroy
Windy only visualizes the predictions of numerical weather models. Which model did you watch?
Here is the comparison between Reported wind at Springbank airport and the NAM forecasts. This does not seem so bad, 23kt forecast for 21.4kt reported but with a time shift of 48 minutes.

ECMWF is weaker with 17kt and GFS worse with 12kt.
So try which is the best model for your area.

Hi,
Please could you send some screenshot showing this bug.

@impi
All GRIB files that you can received via several web app that you mentioned are GFS files which are free. Some of them offer ECMWF GRIB files but you must subscribe monthly payements.

@marijnacht
Unfortunately Windy is not prepared to offer this mode. This is mainly due to the licensing agreements with ECMWF.

However if you think about a solution to keep 3 to 5 days of weather displays in memory, that could be a good alternative, even if, in this case data, are not freshly updated.

@ivo
OK I have updated and got the 17.xx version, with the option « Donate »

@jeanernest
On the website, just tick here:

@csabatatar
I have seen that a few days ago on the phone app. But since that it has disappeared. And I don’t remember seeing an announcement about it.

@manu33
You must make the settings change on windy.com and be logged in with your Windy account. It is not possible to do this change in the phone app.
In the left high corner menu (3 horizontal bars), select, « Paramètres » > « Modifier les couches de couleur »

Then you see « Select overlay Vent [wind] »
At bottom click on [show gradient].
It opens a small window that you can enlarge.
Delete all codes in this window.
Then copy the code in my post about wind settings and paste it in this window.
Click on [import gradient].
And finally click on « Save »
The modification will be applied in your phone app too.
Bon courage !

@manu33
I agree with you. This the reason why I have changed the settings for wind speed on my side. You can use the same settings just by copy and past. This colour range doesn’t show redondant colours. Here is the way how to do that:

@edneff
These lines correspond to altitude levels. They allow to know the altitude of the clouds shown on the Meteogram.

• 700h means 700hPa. This altitude is expressed as atmospheric pressure level.

• 3km is the altitude in metric

• FL100 is used by aviation as flight level. FL100 correspond to 10000ft level.

@cherrycoke11
In addition you may try Squid sailing
It’s free, including the mobile app, but with less advantages compared to Windy. This routing app is based on GFS for the free version, other models are available with monthly payement.

@svsecondchance
That’s absolutely normal. The arrows are in the same direction of the « particule animation ». In the conventional way to show the wind direction i.e. with the arrows type called « wind barbs », these arrows are also in the same direction of the wind flow and not from where it come.

After few cold days beginning of next week, global models predict a SW flow bringing several storms over Great Britain and Western Europe.
Here is the track of a storm forecast by ECMWF, with deepening at 954 hPa on Irish Sea. The wind field show Hurricane force Winds (> 64kt - 118km/h - 12Bf - light green range colour) over the Scilly !

Of course this 9 days ahead forecast will be surely not realised. But it gives an idea of this violent flow, from Gulf of Mexico to Europe

@sigridl
You will find some discussion about this type of projection here :

https://community.windy.com/topic/7272/borderless-map

A polar projection should be an alternative to the abandonment of the 3D display on Windy.

@turbinesurgeon
You must make the change Celsius to Fahrenheit on the website Windy.com after being logged in. Then it’s automatically applied to your phone app.

@ladyblues23
Unfortunately there no way that Windy provide data in GRIB format by low band width satellite transmission. Here is the reason :

@rimfalcon
The solution is may be here :

https://community.windy.com/topic/6947/widget-issue

Change the units in the website, on the wind colour scale. Then the modification is automatically applied to the phone app and widget.

@tz
Would a stereographic polar projection (plane tangent to the pole) be easier to implement ? It could be an alternative to the 3D mapping and could fill the gap due to the Mercator projection in the polar regions.
Of course it’s a less smart solution than 3D, and it needs 2 views, one for North Pole and one for South Pole.

@wxcycles
Nice pictures !
