South England Rain Radar map goes blank
-
@korina but the old image is NOT displayed. Look at the screenshots I have uploaded. The lltest image is simply blank in large areas. The 2nd to last image has lots of data... This is a real problem.
-
@korina Korina, just to show that this is a systematic problem, the following screenshots were taken from the browser version rather than the app.
You can clearly see that a whole storm system visible on the "2nd to last image" has simply disappeared off the "latest image" in the historical sequence. i.e it is simply not true that "The old image is displayed"
This happens systematically every time I use Windy. It really is not some rare event.
Browser screenshots:
-
@korina Just to demonstrate my point, these images are of 21:45 and 21:50 BST Sunday 8th Aug. You can see again that a whole frontal system data has disappeared in the later image;

@dcampbell305 Bump to stay current

@dcampbell305 Hello, we will investigate it once it happens again.

@korina Now that there is some active weather over England I can show the problem again.
The two attached images show the 2nd to last and last frame in the rain radar plot. You can clearly see that the 2nd to last frame has high activity, but this has disappeared in the last frame.
Data taken 20:31 and 20:40 8th September 2021
The problem seems to be due to the filtering algorithm. You have stated in the past "If the data is not ready, the last image is shown" This is clearly not happening correctly.
Note: This is from the browser version of Windy.com but the app shows identical images.

@korina ...and finally just to show that the storm front was still there at 20:40 the enclosed image shows the data for 20:40 but logged at 21:15....
If you compare this image with the 20:40 image above, you can see there is a lot of data missing when 20:40 was the latest image..
Interestingly this issue really only seems to concern the South of England data sets. Data from other areas (e.g. Ireland, France) seem sound.

@dcampbell305 Hello, we have made some changes and the radar visualization should not disappear anymore before its next update.
-
@korina I confirm that the data is no longer lost on the last frame. Thank you for you efforts
However, this now shows that the time lag to obtain and display the latest rain data seems much longer than with other apps, e.g. the Met Office or The Weather Channel. Can anything be done to reduce this delay so that the rain radar data is more current?
-
@dcampbell305 Hello, we may improve the delay in the future.
