Dear Prof. Houser and Co-authors,

Thank you for submitting your manuscript to the Natural Hazards and Earth System Sciences (NHESS). Your paper “Machine Learning Analysis of Lifeguard Flag Decisions and Recorded Rescues “ has been critically reviewed by outside peer reviewers. After the discussion round, the reviewers recommend reconsideration of your paper following major revisions. We invite you to resubmit your corrected manuscript after addressing all reviewer comments.

When resubmitting your manuscript, please carefully consider all issues mentioned in the reviewers' comments. For a revised manuscript version, in order to make easier and faster for the reviewers to check the final manuscript, we require two separate documents:

1. Author response, it is Revision Notes explaining how and where (citing line number) each point of the Editor's/Reviewers' comments has been addressed. Should you disagree with any part of the reviews, please explain why. At the end of this revision notes a version of the revised manuscript showing the new/changed text using track changes or highlighting. To facilitate further review, add line numbers in the text.

2. A version of the revised manuscript without showing the new/changed text using track changes or highlighting.
Final acceptance is, however, contingent upon satisfactory revision along the lines suggested. Please be sure to upload your revised manuscript back to the electronic database.

Sincerely,

Mauricio González
NHESS associated Editor
