A lot of general disaster preparedness has been intentionally left off, because that's covered in so many other places and because there's a good chance you have them in place at all times.
Obviously you want to have food and water for anywhere from 2 day to two weeks, meds and self/pet/child care essentials, having independent power, water and gas storage is great, but that's all long term planning stuff, not "just got a take shelter in 15 minutes warning" type stuff.
