@petra-pik You are right, it appears you switch to the detailed map with zoom factor 12. I propose when you switch the tiles you switch the webcam icons with it. It was much clearer on lookr.com IIRC.
Ok, I meanwhile found out the most direct equivalent for the old URL to be something like this: https://www.windy.com/-Outdoor-map-map?map,47.483333,8.4,13 (direct, deep link).
I used to be able to see all webcams around a specific lat/lon combination by going to e.g. https://www.lookr.com/map#ll=47.483333,8.4&spn=0.05,0.05.
What is the equivalent URL on windy.com?
