Where would irregular be a reasonable alternative to anomalous?

When is it sensible to use unnatural instead of anomalous?

The meanings of unnatural and anomalous largely overlap; however, unnatural suggests what is contrary to nature or to principles or standards felt to be essential to the well-being of civilized society.
