Reviewer 1 - line 120: There are two dots (..). The above changes have been addressed. - p. 23, About channel morphology control on ice break-up, I suggest to read and to add this reference in the discussion. DE MUNCK*, S, GAUTHIER*, Y. BERNIER, M., POULIN*,J. CHOKMANI, K. (2011) Preliminary development of a geospatial model to estimate a river channel’s predisposition to ice jams. CGU HS Committee on River Ice Processes and the Environment (CRIPE), 16th Workshop on the Hydraulics of Ice Covered Rivers, September 18 – 22, Winnipeg, Manitoba, 11 pages. I have also included the above reference on page 23. Reviewer 2: - The interpretation of Fig 8 around lines 85-95 needs to be significantly improved (as I noted already in my first review, but wrongly referring to albedo, instead of Precip and Air Temp). The authors' interpretation about correlation between precip and temp, and break-up anomaly, seems rather random to me. I find for instance years with similar break-up anomalies, but different ones for precip and temp. (e.g. 2005, 2007 and 2010). Also else I cannot really follow the authors discovering a clear correlation. To make this 'visual' statistics acceptable for publication, the authors need to provide quantitative standard statistical measures, in that case multvariate ones, that show that the correlation claimed is not a just a random product, but statistically significant. Figure 8 has been removed along with the supplementary explanation from the text (lines 85-95). Editor comments: - Given your short period of data, I suggest you revise your abstract to focus more on the novel aspects of your methodology. The Abstract has been revised and updated. - Lines 83-84: Brown and Derksen (2013) is not an appropriate reference for ERA- interim. The recommended citation is Dee et al. (2011). Also, ERA-interim is currently available up to July 2015 so the comment “until 2011 only” is incorrect. Dee, D. P., Uppala, S. M., Simmons, A. J., Berrisford, P., Poli, P., Kobayashi, S., ...

Soc., 137, 656, DO -10.1002/qj.828 The correct reference has been included. - I agree with Reviewer 2 that your interpretation of Figure 8 is not supported by the data. From eyeballing the numbers off your figure there is only a weak correlation between air temperature and break-up (-0.4 which is not statistically significant for the sample size). The correlation between break-up and precipitation is close to zero. I tried a multiple
