We forget how much of our daily comfort and safety depends on electricity and other sources of power.
ATM's, gas station pumps, traffic lights, sump pumps, elevators, sewage systems, communications systems, lighting, air conditioning, heating, water purification, refrigeration, cooking, and transportation are just some of things you might have to do without.
Emergency services (police, ambulance, fire) will not be able to help you during or even immediately after a storm. There might be looters out loose.
Tall buildings can still be damaged by crumbling foundations, flooded basements, no working elevators, broken windows, and backed up sewers.
