I agree with your English. However, to the FAA, the forecast is "known".

The placards do not say just "known icing". They say "known icing
*conditions*". And both the FAA and NTSB hang their hat on saying that if
"icing conditions" are forecast, then they are known and you are in the
prohibited range even if "icing" does not exist.
