In addition to "regular" preps for bugging in or bugging out, I have several tarps, plastic sheeting, contractor bags, cordage, duct tape, wire, hand and power tools, and the like. I should be able to repair or at least temporarily mitigate a certain amount of damage to my house.
The other storm-specific prep I have is a generator large enough to run both of my sump pumps, and enough gas to keep it running continuously for a couple of days.
