Today, a new radar is active on the Croatian coast, it covers the north, middle, and parts of the south Dalmatia. The information is available publicly by DHMZ (Državni Hidrometeorološki Zavod, Croatian Meteorological and Hydrological Service).
The radar is named MRC Debeljak
The composite is here
It would be great if you can integrate it into Windy :)
EDIT: For some reason, I can't put the "&" sign into a link so it won't load, manually add the "&" between "mjerenja" and "param".
