Dear Authors,
Two reviewers have offered comments to your manuscript, which I believe can be addressed after minor revision. I thus invite you to provide a detailed reply to the comments of both reviewers and consider them in a revised version of the paper, which I will further review before a final decision for publication.
Thank you for your contribution to the Special Issue and I am looking forward to receiving the revised version.
Best regards,
Maria-Helena Ramos.

Dear authors,

thank you very much for your revised version and contribution to the Special Issue "Sub-seasonal to seasonal hydrological forecasting".

I read your reply to reviewers and I think you have addressed their remarks accordingly. I have a few technical issues from my reading of the final manuscript, which are listed below. I think they can be considered when uploading the final version for publication (no need for additional review by reviewers or Editor).

These technical issues are:
- Fig. 4: I agree with the comment of reviewer K. Engeland about the fact that the 95% confidence intervals are too large since they encompass all but 1 observation, when they should, in theory, encompass all but 5% of the observations. The differences may be due to observational/sample uncertainties, but I suggest the authors to consider adding at least one sentence to clarify this point.
- In some places, I think the use of a comma (,) would facilitate when reading long sentences. I would review the whole manuscript for the use of this particular punctuation mark (e.g., page 14, lines 3-7; page 16, lines 21-24; page 18, lines12-13; page 20, line 24; page 21, lines24 and 28, etc.).
- Page 14, lines 3-7: please review the sentence for the use of commas and also for the repetition of the words "lake levels"
- Page 14, line 14: shouldn't it be, "...from using seasonal rainfall forecasts, with..."?
- Page 16, line 16: I suggest to break the sentence: "... these relationships. Fig. 6 shows..."
- Page 19, line 16: period (punctuation mark) is missing at the end of the sentence.

Thank you again for your manuscript.
Best regards,
Maria-Helena Ramos.
