AROME ANT 12Z Forecast Incomplete

Hello Windy team,

I’ve noticed that the AROME ANT 12Z run on your app only shows forecasts up to +36 hours, whereas on other platforms like Météociel, the same run provides data up to +48 hours.

This is strange indeed.
In Windy last update of the model, 00Z run, the max lead time is
AROME ANT (Antilles) +33h
AROME REU (LaRéunion) +42h
AROME-HD (France) +42h

Météo France gives a +45h max lead time

It is for AROME ensemble forecast. I guess AROME deterministic is the same.
So I don’t know how Météociel can display 48h.

I think it’s because in the past, AROME ANT provided forecasts up to 36 hours for the 00Z and 12Z runs, and up to 48 hours for the 06Z and 18Z runs.

I found a similar link that can provide data up to 48h hours : https://donneespubliques.meteofrance.fr/?fond=produit&id_produit=241&id_rubrique=51

Hi @drcapala and @idefix37, yes, You are right. As far as I know, AROME forecasts got recently (not sure how long ago) updated and all forecast runs are now 48h in the future.

Using this newly available data is on my TODO list.
