A popular way of guarding against this kind of catastrophe is storing food at home. This is called Long Term Food Storage, Emergency Essentials, or Emergency Survival Foods and there are dozens of companies selling food specifically for this purpose. The best, including those listed below, have great tasting products with a long storage life at a reasonable cost. 
Individual survivalist preparedness and survivalist groups and forums—both formal and informal—are popular worldwide, most visibly in Australia,[93][94] Austria,[95] Belgium, Canada,[96] France,[97][98] Germany[99] (often organized under the guise of "adventuresport" clubs),[100] Netherlands,[101] New Zealand,[102] Russia,[103] Sweden,[104][105][106] the United Kingdom,[107] and the United States.[23]
While survivalists accept the long-term viability of Western civilization, they learn principles and techniques needed for surviving life-threatening situations that can occur at any time and place. They prepare for such calamities that could result in physical harm or requiring immediate attention or defense from threats. These disasters could be biotic or abiotic. Survivalists combat disasters by attempting to prevent and mitigate damage caused by these factors.[31][32]

EAS Participants provide a critical public service to the nation as the resilient backbone of alert and warning when all other means of communication are unavailable. EAS Participants include all broadcasters, satellite and digital radio and television, cable television and wireline video providers who ensure the system is at a constant state of readiness.

Another possibility is a pre-fab concrete tornado shelter delivered to your site. They can double as storage sheds in good times, including as pool houses. Google ‘precast concrete storm shelter’ and variations on that. Anything which can stand up to a tornado would stand up to a fair blast. Not ground zero, but if you are worried about nuclear war, you probably don’t live at ground zero.
The U.S. Department of Homeland Security (DHS) in their "If You See Something, Say Something" campaign says that "the public should report only suspicious behavior and situations...rather than beliefs, thoughts, ideas, expressions, associations, or speech...".[86] However, it is alleged that a DHS list of the characteristics of potential domestic terrorists used in law enforcement training includes "Survivalist literature (fictional books such as Patriots and One Second After are mentioned by name)", "Self-sufficiency (stockpiling food, ammo, hand tools, medical supplies)", and "Fear of economic collapse (buying gold and barter items)".[87][88]

That settlers son in law was a Colonel that had a lot to do with the trail of tears. Jackson gave him 10,000 acres here when it was over. The dog buried in the cemetery was given by Jackson. Found a tomahawk hid behind the stairs. It was a simple house but had a stairway up to the attic. Just simple open framed steps. Also a set of clinchers still worked like New. Square nails, drilled holes and whittled pegs, mortice and tenon joints, hand hewn logs. Up on boulder rocks, no bricks or concrete. There are two more old ones i found in the woods that you can walk under. Chimney on each end. One has a separate log cookhouse with a large wide rock chimney for cooking. Lot to be learned there.
Fires happen at the best of times—when the SHTF, they are even more likely to happen. You need to be prepared. And you will be with the Firemask as part of your prepper gear This is a respiratory device that will protect against smoke inhalation, fire, and radiant heat. It also protects against carbon monoxide, ammonia, hydrogen sulfide, and other toxic gases.
Good point. But if you do have your drives and at least one very simple computer stashed away in an emp-proof container it will once again become useful when they eventually get the lights turned on again. And make no mistake about it. We will rebuild our civilization. Up to that point, yes, I entirely agree with you that hard copy is easier to deal with.

Glad i started prepping. I’ve slacked off for awhile, but i’m back. Last year my cities water was considered undrinkable for about 3 days. Couldnt drink it, use it in anyway, not even a shower. Was said to cause vomiting, rashes, etc. You couldn’t go to a store in this city and find water any where. It was crazy. I had about 6 10 gallon jugs of water, stored away. Another thing was the whole gun ban hype after sandy hook. For a long long time you literally couldn’t find ammo. Or if you did you were paying a few… Read more »

I would like to add something, not necessarily to the list, but more like “food for thought” ideas that could very well save you and your family’s life. Living in the South, you “will almost” grow up around some natural disasters, whether it be a hurricane or tornado, most of us here take “prepping” very serious..and we learn a lot from those disasters also (I.e. Hurricane Katrina). I grew up around great-grandparents, grandparents, parents, other relatives and friends, who have a garden, almost for the entire year. Learning to can and freeze food was as natural as brushing your teeth! During the summer, when school is out, we shelled peas, shuck corn(yeah say that fast!), canned beans and tomatoes, picked berries, smashed berries, and, on occasion, churned butter! I wish I had a dollar for every pea I shelled! I be richer than Midas! Knowing these “techniques” can make a huge difference in feeding your family for several months without electricity. There have been lots of times when we would get lunch or diner straight out of the garden, washed and prepped, cooked, and on the plate in a couple of hours. No storage. No refrigeration! Scraps of food went into the garden or compost. And you can cook this stuff straight over an open fire. Two words…”cast iron”…it is a very good investment…it is great to use anywhere…open fire or stove! You don’t have to wash cast iron(I know it does sound gross, but believe it or not, that is the “beauty” of cast iron)..you wipe it out and keep it seasoned. You can cook anything in cast iron, from biscuits…to a cake! People with cast iron can cook almost forever! I would view it as essential. Enough about the garden.
Earlier this year the hands of the Doomsday Clock moved to two minutes to midnight, as atomic scientists announced that the world is closer to annihilation than it has been in decades. Is it any wonder then that the worldwide phenomenon of prepping, in all its camouflaged, gun-toting, canned-food-hoarding glory, is spreading as global anxiety about everything from thermonuclear war to climate change takes hold.
I guess I have been taking a longer view. Any disaster will shut down delivery to stores so all fresh greens will stop. I remember that during the same period in history the Polynesian sailors were able to stay out at sea much longer than European sailors and didn’t know what scurvy was. They used bean sprouts to supplement their diet. Last Christmas I asked my wife for a bean sprouter. It has been a lot of fun playing with, eating and learning to work with a multitude of seeds. One interesting fact was that wheat sprouts have an interesting sweat taste. This got me gathering information about what makes good sprouting seeds and it seems that fresh and non-treated (as usually done by our commercial world) is the critical factor. It was about the same time I learned that one of my nearby farm friends has a crop of winter wheat being harvested this July and would have no problem giving me a 5 gal bucket. (@ ~$8.00 a bushel) So I started looking for a food grade bucket and learned that both Jewel and Dominics (grocery stores) go through a number of 5 and or 2.5 gal buckets weekly or daily, (labels usually describe cake icing) for free. Sometimes I have to clean the remnants out, but that’s not to hard and the price is right and they are food grade. I am excited to have fresh wheat and two uses for wheat. Opps I still need to get a flower mill. One step at a time. I have the buckets now.

I keep several five gallon gas cans filled and ready for use. I don’t put any gas stabilizers in them, but I have stabilizers on hand. At the end of each quarter, I fill the cars with the gas from these cans, and go and get fresh. If the SHTF, and it looks like more time would be needed for the gas to keep, then and only then would I add the stabilizers to the gas.
Gerald Celente, founder of the Trends Research Institute, noted how many modern survivalists deviate from the classic archetype, terming this new style "neo-survivalism"; "you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This [neo-survivalist] is a very different one from that".[27]
I think the FaceBook comment, “the electric company knew days in advance the ice was coming and THEY did not prepare.” perfectly demonstrates Mr. Martenson’s approach…..”the ‘Crash Course’ was the problem definition….but, “the book, Prosper, is the solution space.” Some saw the ice storm coming, but seemingly did not prepare (mentally, physically or spiritually); expecting the electric company to make it somehow disappear…..(normalcy bias?)
Before I get into what the MREs from Meal Kit Supply tasted like, I wanted to set expectations here. Just like I have said in other reviews on long-term storable food similar to this. When you tear open a bag like this, you aren’t getting fresh ingredients from the garden prepared by a classically trained French chef. You are getting food that was designed for the military to pack enough calories in there to keep them alive, be waterproof, tolerate being mistreated and last for 5 years sitting in a warehouse most likely. If you are expecting Ruth’s Chris here or maybe even Golden Corral, you might be in for a surprise.

Many municipal water supplies are disinfected with chloramine now, not chlorine. (That's Texas law, for example.) The difference is that chlorine evaporates, while chloramine does not. It can only be removed by chemical reaction or charcoal filtration. For that reason, I avoid tap water as much as possible. But one nice thing about it in a survival situation is that, based on personal experience at least, it does not go bad.

How would you like to call a missile base home? America built 107 missile bases around the country during the arms race in the 1960s, including the Atlas F Missile Silo located about 130 miles north of Albany. It was decommissioned after only four years and has sat dormant and neglected for decades, eventually selling for $160,000 in 1997 and again for $575,000 in 2015. Bear in mind that the “super hardened” facility, built for the equivalent of $100 million in today’s dollars, was designed to withstand almost any bomb imaginable.

You should have two weeks’ worth of non-perishable, easy-to-prepare survival food in your home — no good prep is complete without it. If you want to skip the DIY labor and just buy something off the shelf, we spent 180+ hours reviewing over $2,000 worth of the most popular products. After testing 11 options from 7 companies, the best choice for most people is the new Emergency Essentials Premier bucket. Three of which cover two people for more than two weeks for $379.
The remote island nation, clinging to the southern part of the globe 2,500 miles off Australia’s coast, has 4.8 million people and six times as many sheep. It has a reputation for natural beauty, easy networking, low-key politicians who bike to work, and rental prices half those of the San Francisco Bay Area. That makes it an increasingly popular destination not only for those fretting about impending dystopia, but for tech entrepreneurs seeking incubators for nurturing startups.
Perhaps the most unusual thing about the female prepper lifestyle is that it suggests a counterintuitive movement through time: a return to a slower, more elemental way of life, one that eschews the conveniences of modern consumer society in favor of the empowerment that comes from doing things yourself. Some of the women I spoke to said being a prepper helped them carry on the same old-fashioned life skills — like gardening, canning, and smart budgeting — that helped their mothers and grandmothers during the Great Depression. Others harkened back to the homesteaders of the late 19th and early 20th centuries, whose pioneering settlement and cultivation of the Great Plains form the backbone of the American myth of self-reliance.
Followers of James Wesley Rawles[45] often prepare for multiple scenarios with fortified and well-equipped rural survival retreats.[46] This group anticipates a near-term crisis and seek to be well-armed as well as ready to dispense charity in the event of a disaster.[43] Most take a "deep larder" approach and store food to last years, and a central tenet is geographic seclusion in the northern US intermountain region.[47] They emphasize practical self-sufficiency and homesteading skills.[47]
You may feel helpless if you have not been an outdoorsy or rugged person for most of your life, but the most essential lifesaving and survival skills and concepts are easily learned, if not mastered. Below is a list of several core skill sets you should make a point to get trained on and practice when you can. In all but the smallest towns there will be someone who has something to teach you about all of them.

Don’t stop there. Take a hard look at demographics.  Are you in a city where gangs, mobs or terrorist attacks are likely?  Do you live in a remote area where the failure of transportation systems or the lack of fuel will cut you off from supplies arriving from the rest of the world?  Is your employment situation tenuous requiring that you build up some cash reserves to get you by just in case the job goes away?

I hope this makes sense to you. It sounds like you have already figured out that with a growing teen and two additional children in the household, this will be a good start but that more will be needed over time. By doubling these quantities my guess is that you will be better prepared, food wise, than 90% of the population. And even without doubling the quantities, you will be better prepared.
I find generators that can be transported easily to be a way better idea than just regular generators – don’t know why and let me know if you agree/disagree in the comments. Thanks to the fact that generators have been around for a long time (unlike solar panels I mean), you can get some great products for what’s, in my opinion, a perfectly reasonable cost. And while I’d prefer to have a solar generator like the one listed at #6, something like this is much more affordable, and gas is easy to get, so I will likely end up with a portable gas generator first.
At a minimum, a good framing hammer, hand saw or hacksaw, medium prybar, axe, shovel, vise grips, screwdrivers, fixed blade general purpose knife, small mechanics kit with wrenches, can of all-purpose lube, sturdy cordage (paracord or accessory line) and duct tape. Ensure you have an adequate wrench or similar tool that can shut off water and gas valves in and around your home.
Liz – I’m not normally one to call someone out… But… You’re WRONG! The body ABSOLUTELY cannot survive without carbohydrates. Scientifically impossible! You might want to have a full blood workup done and an exhaustive vitamin panel. No way, no how, you’ve been on a meet and water diet for a year! After a couple of weeks your body would go into ketosis. Not long after that, absence of Carbs would start to affect brain function. Not sure what you’re trying to accomplish with your comment, but you’re “advice” will be sending people to the hospital!
“Everything started flying out,” she says. Buckets and cans rolled out of the pantry and down the side of the mountain. Hurricane Maria claimed almost all the food Jennifer had stockpiled, in addition to more than 30 chickens, two cows, four pigs, six ducks, and a turkey. “I had prepped for two and a half years, and I ended up with preps for six months,” she says.
The largest doomsday bunkers in the United States are not only for civilians. In 1992, a Washington Post writer by the name of Ted Gup exposed the hidden bunker at Greenbrier Resort in West Virginia. For decades the retreat of government and Presidents, the resort has a massive bunker located below the West Virginia wing complete with an auditorium large enough for the House of Representatives and a separate space for the Senate Chamber. Holding a television studio, hospital and living quarters for all members of Congress in the event of a nuclear war.  Tours are now available of the bunker to visitors of the resort.
While survivalists accept the long-term viability of Western civilization, they learn principles and techniques needed for surviving life-threatening situations that can occur at any time and place. They prepare for such calamities that could result in physical harm or requiring immediate attention or defense from threats. These disasters could be biotic or abiotic. Survivalists combat disasters by attempting to prevent and mitigate damage caused by these factors.[31][32]
In his book Dancing at Armageddon: Survivalism and Chaos in Modern Times, Mitchell, the sociology professor, develops a working theory of survivalism as a response to living in a society where every object we could possibly need is already taken care of for us. “The shelves are full, and the channels are full,” Richard tells me over the phone. “This is a response to a culture that has stripped away from us our sense of efficacy, our capacity to craft culture.”
Many of these foods are simple meals that require you to add water and heat (such as MRE's, or Meals Ready to Eat). However, if you buy individual bulk ingredients you can create more of a gourmet pantry which allows you a much greater range of meals to prepare—powdered eggs, spices, all sorts of flours, honey, etc. These foods are not only great for food storage but also for camping trips, especially if your camp kitchen is serving a large crowd.
From the remote road, you first come across a landscape of hundreds of earth-covered domes in perfect rows with their concrete exteriors providing a stark contrast to the lush surroundings. This was Fort Igloo, where for over 24 years the US Army’s Black Hills Ordnance Depot created jobs for thousands of workers and their families. This was a community that many former residents still have fond memories.
Yup, rocket stove DIYs are easy to find, but to each his own and if I can afford to spend $150 on a good knife, I can also afford to spend the same on a rocket stove that’s good looking, lightweight, extremely portable and a one-time buy. It’s the kind of thing I wouldn’t mind pulling out in front of the sheeple to have a BBQ or go camping with, and that makes me happy one way or another. Just like the rain barrel, I could DIY one myself, but it’s unlikely to look even a fraction as good (especially with my incredibly poor DIY skills), and so I’d rather just buy one and be done with it.
Even though I have a good start on my food pantry, it is always a good idea to look at others ideas. I had not thought of bulk pancake mix. I am a single person and got a great deal on Bisquick shake and pour ($1.00 each) I bought 2 dozen! I don’t really care for pancakes on a regular basis but once in a while… That all being said, I did purchase a vacuum sealer and have made good use of it. I also have a large dehydrator and visit the farmers market often for goodies to dehydrate and seal. When I have purchased these 20 items, I am then on to other needs such as shelter, etc. I have a lot of camping gear but not a good tent if I should have to vacate. Thank you Gaye – keep up the good work.
Always store your bulk foods in food storage containers. I have seen literally tons and tons of food thrown away because they were left in sacks, where they became highly susceptible to moisture, insects and rodents. If you are using plastic buckets make sure they are lined with a food grade plastic liner available from companies that carry packaging supplies. Never use trash can liners as these are treated with pesticides. Don’t stack them too high. In an earthquake they may topple, the lids pop open, or they may crack. A better container is the #10 tin can which most preparedness companies use when they package their foods.

You can find rice in any store in this world. It’s a cheap and healthy addition to your emergency survival foods stockpile. It will provide you with the carbohydrates that will fuel you through a disaster. Half a cup of dried rice makes 1 cup of cooked rice. When it comes to survival foods, rice will help you stretch your food supply without breaking the bank. Every time you go to the grocery store you should pick up a large bag of rice to add to your emergency food supply.
I stored Flour, Sugar (white & Brown) along with yeast, baking soda/powder and crisco. My plan is to use a Bread machine to make bread. I have a large generator to power essential items. I also have a small generator (very quite) to power things during night time hours or my camper that has an oven we could use in an emergency. The best thing you can do now is to sit down and go thru some various scenarios in your head with varying degrees of severity. Then, write it all down on paper in note/bullet statement format. When you’re stressed-out is not the time to formulate a plan.
Thrive Life Foods. This is my favorite of the freeze dried foods for one simple reason- They sell ingredients, not dishes. With this brand, you can stock up on nimber ten cans of ingredients that you use in favorite dishes. You are not constrained and can prepare the meals that your family is used too eating, cooked from your standard recipes. Unopened cans have at least a 25 year shelf life, and some items are available in 5 gallon buckets. Thrive Life foods can be found online.
