We went through Irene and were without power for about a week. I have a back up generator for the snakes and essentials. So, we are fine. However, if as an additional back up I keep a full case of 40 hours heating pads normally used for shipping. If worse comes to worse, I can drop a heating pad in each tub to provide some heat.
From the looks of the storm, we will see some of it, but not the brunt - unless the path changes.
