Hello,

Yes it's a storm now! But a it's a very small one at least. Its convection area is very small and thunderstorms appear to be quite small compared to other typical tropical storms. However at this moment thunderstorms tops are reaching FL450. That represents a lot of water that could surely cause flash floods and mudslides...

People from Guadeloupe to Grenada should be extremely careful regarding floodings, wind gusts and also waves caused by this little storm.

And ahah yes I didn't notice that about island names :)

Ahhh interesting. I thought ground clutter was removed during radar calibration or something. Is there a way to have automatic ground clutter filter on Windy ?

It is strange that it's not a constant problem though, because now it's gone, even on Windy. I wonder if temperature, moisture or other phenomenom can increase the ground clutter.

EDIT:

Well, it's well explained with also other info on the website you provided, thanks.

"Under highly stable atmospheric conditions (typically on calm, clear nights), the radar beam can be refracted almost directly into the ground at some distance from the radar, resulting in an area of intense-looking echoes."

Yes, I don't have this problem using firefox... And there is no bug when passing the day change line near new zealand on firefox by the way... I should probably use Firefox... But I've got all my pages and setting on chrome :) I'll just wait and see if I can fix the problem. Thanks

Ah cool I didn't know about the fronts. And yes the wind accumulation layer is well made.

Thanks

Arome ensemble model (2.5km) for a part of Europe and lesser Antilles are also available for free since March 2017. There is so much information in it!

That is the french met service website.
They also provide French, caribbean and some international radar data but it seems that it's not free...

@Gabou971 WOW thx
