Official means one official source published the record.
The label describes how the record was filed. It is not a statement about anyone's intent.
High, medium, and low are ARC Warning display labels for how the record was filed. They are not a forecast.
When the source published its own number, such as an earthquake magnitude, that number is the measurement. The display label does not replace it.
