I have selected a rain summary (souhrn deště). Is the pink color really 1 meter? E.g. 1000 mm? Prays to Slovenia.
You are probably talking about Rain accumulation. And 1m (or 1000mm) is not a mistake as explained here:
You are right, the pink colour corresponds to a very wide range from about 100mm up to 1000mm and much more. It can be changed fortunately as explained by same link above.
