There are many types of disasters. Some are man made. Some come from mother nature. Some are not much worse than a broken arm, and some could be the end of mankind. Some you have plenty of time to see it coming and prepare. Others occur at the blink of an eye. Some you can prepare for. Others there are no material preparing for the event.
Take a hurricane. Most people, these days, have many days to see it coming, decide what to do, and take actions.
On the other hand, a grid down event would most likely not provide any prewarning.
Question: What circumstances would cause you to take immediate initial steps for a wide-area long-term grid down event?
How would you make the determination that the power outage was really a grid down event and not a local failure soon to be repaired?
The faster you made that determination, the sooner you could move on to taking the first few vital initial steps - filling tubs with water, getting prescriptions filled, topping-off water, food, gathering loved ones, etc..
