Dear Roberto Greco and Luca Pagano,

your manuscript entitled "Basic features of the predictive tools of early warning systems for water-related natural hazards: examples for shallow landslides" was reviewed by two independent referees.
Both highlighted some issues in the paper and made some comments and suggestions, which can be shared. On the other hand, your point by point replies were detailed and useful for the improvement of the manuscript.

Referees proposed minor and major revisions for your work before being accepted for publication. Overall, my opinion is that that your work has potential and it is worth to publish it. Thus, I have decided that it can be accepted after a major revision. The reviewed manuscript will be briefly checked again by referees and me before proceeding for publication.

In preparing the revised version of your work, please consider all the comments and suggestions made by the two referees, and make them visible.

Thank you.

Sincerely,
Stefano Luigi Gariano
NHESS Guest Editor for the Special Issue

Dear Authors,
 
the second check made by the reviewers highlighted that you have improved considerably your article, as to being acceptable for publication.
However, they added few comments and corrections that I think will be useful for a final amelioration of your work. I suggest to follow the reviewers' advices.
After these very minor revisions, your article can be accepted for publication in the NHESS Special Issue.

Thank you very much.

Sincerely,
Stefano Luigi Gariano
NHESS Guest Editor
