Here in the northeast, we were hit twice this year with bad storms that caused heavy tree damage in large areas, resulting in several hundred thousand people losing some or all of the following:
- Electricty.
- Landlines - including normal telephone service, DSL and cable.
- Cell phone service. Not all towers have backup generators and batteries, and by 24 hours after Irene hit many of the ones that originally still functioned had stopped working.
- Road access. Many roads were blocked for several days by trees and/or downed power lines. Some people were trapped in their homes and apartments by fallen trees and/or wires, with no way to call to get help.
In some cases entire towns did not have power, phone service or working gas stations for over a week.
Basically, there were clusters of tens of thousands of people stuck in their homes without electricity, phones, gas, water or heat.
This is probably the closest to any large scale SHTF scenario I've experienced. Here are a few observations.
1) The shelves will be bare at stores. In both cases, but particularly Irene where there was more warning, the shelves were cleaned out of essentials at local grocery and convenience stores a couple of days before the storm hit. The concept I often see in post-apocalyptic films of just walking into an abandoned store and loading up on anything useful is mostly pure fantasy. Stockpile fuel, batteries and non-perishables now when they're available.
2) Keep cash on hand. Finding a working ATM or bank branch with power was a chore or impossible for many people. And many of the businesses that were open couldn't take credit or debit cards because they didn't have power and/or a working terminal (phone lines were down). What's even more worthless than federal currency? The plastic used to make credit cards.
3) Diversify your fuel. The regular gas sold out first at local stations, then the higher octane ratings. Diesel was last. It makes sense to have at least one thing around that runs on diesel in case that's the only fuel you can find. If all of your vehicles and generators run on regular gas, you could be SOL in a real crisis. Also, having natural gas appliances or an outdoor grill is advantageous.
4) Keep a small stockpile of electrical adapters and parts. That generator is no good if you don't have the right plugs or wiring to hook it up. Finding the right plugs and adapters was near impossible without traveling out of state. They're not items that stores carry in large quantities to begin with, and several enterprising individuals bought the most sought-after parts and were selling them at 3-4 times normal retail to the desperate and impatient. Also, your generator can and will fail when it's most needed, because if you're like me you don't run it very often and then when you do you work it overtime. Keep spare parts for that, too.
5) If you or your family require prescription medicine, you may not be able to get it in a crisis. Many of the pharmacies were closed because they didn't have power, and there were shortages of some items at the ones that were open because of out of town customers. Many people reported problems getting prescriptions filled at different pharmacies than they normally used. This area requires careful thought and planning - do you have a backup pharmacy, can you stockpile or get extra of some medications, are there non-prescription alternatives you could use in a bind?
6) Get locking gas caps for all of your vehicles.
7) Stay friendly with your neighbors, because some day you may need each other more than you think.
8) Learn conflict avoidance and resolution skills. Many fights broke out here at gas pumps that were completely avoidable.
9) The newspaper becomes a lot more useful when everything else isn't working. That, and a good radio will help you stay in touch.
