The manuscript introduces an application of artificial neural networks (ANN) that both reviewers note (and I agree) has the potential to be a novel and useful contribution. Little attention has been paid in the literature to the use of ANN for hydrologic applications, particularly in a practical application such as flood warning. Both reviewers indicate, however, that major changes are needed to enhance the clarity of the text and address some technical questions about the proposed methodology. I recommend that the author revise the manuscript as they have indicated in their responses to the reviewers. Because these changes are substantial, the manuscript will then be sent for additional reviews.

The paper has now gone out for re-review after the first round of comments and revisions. The reviewer found that the manuscript is suitable for publication subject to minor revision. I agree with this assessment and I would now request that the author revise or respond to the minor revisions noted by the review. I would also ask the author add labels to the axes in the figures and explain any abbreviations in the table and figure captions. In particular, figures 4 and 5 are missing labels on the figures.

I look forward to reviewing the revised version of this manuscript.

I thank the author for their incorporation of the minor comments from the last round of reviews. I would ask that the author to consider one final careful review of the manuscript for grammar and clarity and also some further wording changes when submitting the final version for publication, specifically:

Page 8, lines 4-6: Instead of the sentence beginning "Even if of course..." change to "Nine of the the 300 locations had less than 8 years of data and therefore, all records were deemed to be sufficient for the purposes of this study."

p. 9, lines 18-19: After the semi-colon, consider changing the text to read: "there is not a predefined number of classes; a parsimonious output later was chosen that is formed by three nodes in a row, each one corresponding to a call, to ensure the resulting sets were not too dissimilar."

p. 10, line 6: Extra commas around the phrase "in particular" would help increase clarity.
