You know that Windy does not design any weather models. They are developed by national weather centres.
But there are some meteorological events which are difficult to predict precisely at a location, such as convective rain. In any case it is useful to look at the rain map to see the precipitation chance in the neighbourhood.

‘In the south’ but where? There is no Hurricane predicted in the Southern Hemisphere. So could give more details about what you call ‘in the south’. Otherwise what can we say …

Hi @SpringGoat , this is not a bug. Please check this link: https://community.windy.com/topic/6995/the-forecast-changes-depending-on-the-zoom/2

Hi @helijoc , it's not a bug. We were discussing this issue some time ago: https://community.windy.com/topic/6995/the-forecast-changes-depending-on-the-zoom/2

@thebigmuzzy
There is no need to zoom to a level lesser than the model's resolution.
e.g. ECMWF has a resolution of 9 km.
Do not expect reliable changes in locations less than 9 km apart.
Only interpolated values.

but occurs at any point of Spain

Choose 10 days rain accumulation

@LLXC This has been a thing for a while. From what I understand, it is an issue with the interpolation. As you zoom in, the interpolation becomes a slightly higher resolution. I think it is a minor issue and don't think much of it. I've only noticed a difference of one or two units as I zoom in so it's not that big of a deal for me.

What I would recommend is zooming in as much as you like to get more accurate forecast readings.
