Winterizing pool in Northern Michigan

I am about to attempt not covering my pool. It is already frozen over with about an inch or two of ice. It might thaw out again before the deep freeze but, either way I don't want to do it. I have done all the usual things like drain below the skimmer and remove all pumps, etc. I just don't think it is worth doing anymore because I don't have a debris problem. I am just wondering what I should keep in check besides excess snow cover displacing the water and blowing out the sides? Any input would be much appreciated. Thanks
