Tier 02 · Sustain
Hurricanes that knock out power for a week. Ice storms that close roads for five days. Supply chain interruptions that empty shelves. Two weeks of self-sufficiency is where most households should actually live — and where most never quite arrive.
When this tier matters
The 72-hour baseline covers most disruptions. These are the ones that don't.
Hurricane Maria · 2017
Power loss across Puerto Rico lasted weeks for most of the island and months for some neighborhoods. Water systems went down with the grid. Households without 2-week reserves depended entirely on the slow arrival of federal aid.
Texas freeze · February 2021
Millions lost power for four-plus days during sustained sub-freezing temperatures. Water utilities failed across the state. Hundreds died, many from hypothermia and carbon monoxide poisoning in unheated homes.
Northeast blackout · 2003
Fifty-five million people across the Northeast and Ontario lost power. Most service was restored within two days — but for cities dependent on electric pumping, water pressure failed for nearly a week.
Supply chain shock · 2020
Grocery shelves emptied in April 2020 not because supply failed but because demand surged. Restocks took weeks. The lesson wasn't to hoard — it was that "the store will be open tomorrow" isn't a reliable plan.
Water beyond storage
A family of four needs about 56 gallons for two weeks of drinking and minimal cooking. That's seven 5-gallon jugs. Most households can't store that — so the strategy at this tier shifts from storage to access.
A pump or gravity filter turns any non-chemical water source into drinking water. Sawyer Squeeze (~$40) for backpack-portable use; a countertop gravity system for whole-household duty.
Filters biological contaminants. Not chemical or heavy metal. Know your source.
Most homes have 40–50 gallons sitting in the tank, already plumbed. If the mains fail, shut off the inlet valve and drain from the bottom spigot. That's the family's first two weeks, hiding in plain sight.
Boil before drinking if water has been off for an extended period.
One inch of rain on a 1,000-square-foot roof yields about 600 gallons. A food-grade barrel under a downspout, with a fine-mesh inlet screen, captures more than most households would use.
Check local regulations — collection is restricted in some states.
Food beyond cans
Two weeks of canned tuna is a punishment. The better strategy: shelf-stable staples that rotate into normal cooking, so the pantry is always fresh and nothing goes to waste.
White rice — 25+ years sealed in food-grade buckets with oxygen absorbers. Cooks in 20 minutes. Pairs with everything.
Dried beans & lentils — 10+ years. Lentils cook in 30 minutes without soaking. Cheap protein.
Rolled oats — 5+ years. Eats hot or cold, breakfast or dinner.
Pasta — 5+ years. Cooks fast, kids will eat it.
Cooking oil — 1–2 years. Rotates fastest; track dates.
Honey, salt, sugar — effectively indefinite if dry and sealed.
Dry milk & shelf-stable milk — for coffee, baking, cereal during outages.
A two-burner camp stove ($60–$200) and four 1-pound propane bottles cover two weeks of cooking. Use outdoors or in a well-ventilated garage — never indoors. Carbon monoxide is the leading cause of post-storm fatalities.
A closed full fridge holds safe temperatures for about four hours. A full freezer, about 48. Eat highest-risk items first (dairy, fresh meat, leftovers), then frozen, then pantry.
Medical buffer
The hardest part of an extended emergency, for many households, isn't food or water — it's medication. The conversation to have happens at the next doctor's visit, not during the storm.
Most insurance now allows 90-day fills for maintenance medications, often through mail order. The cost per pill is usually lower. Ask the prescriber and the pharmacy — both ends of the chain have to agree.
Insulin, biologics, some psychiatric medications require refrigeration. A Frio insulin wallet ($25) uses evaporative cooling without electricity. A small 12V cooler that runs off a power station extends the buffer further.
Pain reliever, antihistamines, antidiarrheal, oral rehydration salts, hydrocortisone, cough suppressant. The "stomach bug during an outage" scenario is more common than people expect.
If someone in the household uses oxygen, dialysis, CPAP, or any powered medical equipment, they need their own continuity plan — typically a portable power station and a registered priority status with the utility.
Sanitation
When water stops flowing, the toilet stops working within one or two flushes. Two weeks without sanitation planning is how disease outbreaks happen inside an otherwise-fine household.
The solution is simple, cheap, and worth setting up before the moment arrives — because nobody wants to learn this on the fly.
Two 5-gallon buckets with snap-on toilet seat lids ($15–$30 each). One for liquid waste, one for solid. The solid bucket gets lined with heavy-duty contractor bags and covered after each use with sawdust, peat moss, or kitty litter to control odor and moisture. Total starter cost: about $50.
A pitcher of water poured over the hands into a basin, with soap, beats hand sanitizer for most contaminants. Keep a gallon of water dedicated to handwashing alone, and a bottle of 60%+ alcohol hand sanitizer as the backup.
Two weeks' worth of menstrual supplies. Diapers and wipes if there's a baby. Pet waste bags. Trash storage for sealed waste bags until pickup resumes.
Heat, cold, and air
The strategy at every climate extreme is the same: stop trying to condition the whole house. Pick one room — the smallest, most insulated, with the household in it — and make that room livable.
Close interior doors. Stuff towels under exterior doors. A Mr. Heater Big Buddy ($150) burns propane and is indoor-rated with a CO sensor — sized for about 200 square feet. Sleeping bags rated 10°F below the room temp you expect.
A CO detector with battery backup is non-negotiable. Run any combustion heater with a window cracked.
Stay on the lowest floor. Cover windows facing the sun. Hydrate aggressively — set a phone timer. Wet a towel and drape it over the neck and wrists. Public cooling centers are designed for exactly this; the location is worth knowing in advance.
Heat is the deadliest weather hazard in the United States. Take it seriously.
Indoors, windows closed, HVAC set to recirculate. A MERV-13 filter in the furnace dramatically improves indoor air. A Corsi-Rosenthal box — a 20" box fan strapped to four MERV-13 filters — is the cheap, proven DIY purifier.
N95 masks if going outside is unavoidable. Surgical masks don't filter smoke particles.
Power and communication
Backup power gets sold as one-size-fits-all. It isn't. The right tier depends on what you actually need running.
01
10,000–20,000 mAh USB battery packs. Charges phones, headlamps, small electronics. Enough for the 72-hour tier and short outages.
~$30–$80
02
500–2,000 watt-hour units (Jackery, EcoFlow, Anker). Runs a CPAP overnight, a small fridge for hours, every device in the house for days. Charges from wall or solar panel.
~$400–$2,000
03
2,000–5,000 watt inverter generators, ideally dual-fuel (propane and gasoline). Runs major appliances. Must be operated outside, 20+ feet from any window. Never indoors, never in a garage.
~$400–$2,000
01
No license required. Realistic range of 0.5–2 miles in suburban terrain. Sized for household coordination during a local emergency — checking on the elderly neighbor, reaching the teenager across town.
~$30–$80 per pair
02
A $35 FCC license covers the entire family for ten years. Higher power, longer range, and access to GMRS repeaters that can extend range across a county. The realistic next step for households serious about communication redundancy.
~$50–$150 per radio + license
03
Highest range, biggest learning curve. A Technician-class license is achievable with a few weeks of study. Genuinely useful in widespread events — and a real hobby, which is why most operators stick with it. Optional.
~$30–$300 + study time
The kit, assembled
If you'd rather not research the gear, these are the picks we'd assemble for a household going from 72 hours to a real 2-week kit. Honest costs, honest alternatives. Most pillars can still be DIY'd — this is the shortcut.
01 · Water filtration
~$200–$350 · Berkey, AquaCera, ProOne
A 2–3 gallon ceramic-and-carbon gravity filter that runs without electricity. Removes biological contaminants from any non-chemical water source. Cartridges last about 6,000 gallons each — effectively a decade of household use.
Budget alternative: Sawyer Squeeze ($40) plus two 5-gallon collapsible water containers does most of the same work.
02 · Long-term food storage
~$150 for buckets, mylar, oxygen absorbers, 100 lbs of staples
Five-gallon food-grade buckets with mylar liners and oxygen absorbers, filled with rice, beans, oats, and pasta. Lasts 25+ years sealed. Far cheaper per calorie than freeze-dried kits, and it tastes like food you actually eat.
Shortcut option: a single Augason Farms or ReadyWise 30-day kit ($150–$250) if you'd rather not assemble it yourself.
03 · No-power cooking
~$150
Two-burner propane stove with restaurant-quality output. Fits a real pan, simmers properly, lights with a push button. A 1-lb propane bottle covers 2–3 meals; a 20-lb tank covers a couple of weeks.
Always: outdoors or in a fully ventilated garage. Budget: Coleman Classic two-burner ($80) — decades of reliability.
04 · Single-room heat
~$150
Indoor-rated propane heater with a low-oxygen shutoff. Heats about 200 square feet — sized for one room with the household in it. Runs 3 hours per 1-lb bottle, much longer on a 20-lb tank with the included hose adapter ($25).
Always: with a battery-powered CO detector ($20) running and a window cracked.
06 · Sanitation
~$50 total
Two 5-gallon buckets ($10 each), two Luggable Loo snap-on toilet seat lids ($15 each), a box of heavy-duty contractor bags, and a bag of kitty litter or sawdust. The cheapest, most reliable solution to the single biggest health risk in extended outages.
Worth doing now: nobody markets this to you, and it's the section households most often skip.
All-in: about $1,200–$1,500 for the full kit. With DIY buckets, the budget filter, and the Coleman stove, the floor is closer to $700. The two items worth paying real money for are the power station and the gravity filter — both run for a decade and quietly cover most of what a 2-week tier actually needs.
Common mistakes
Worth knowing because this tier is where most of the money gets spent — and most of the wasted money lives. The mistakes below are the ones we see most.
01
A 5,000-watt generator that burns through three gallons of gas per hour is useless on the five-gallon can in the garage. Sizing the fuel matters more than sizing the wattage. Dual-fuel generators that also run on propane (which doesn't go stale) solve most of this.
02
Untreated gasoline goes stale in 3–6 months. The fuel in your generator can will varnish the carburetor on first use. PRI-G or Sta-Bil ($15) extends shelf life to a year or more — or skip the problem entirely with propane.
03
MREs are designed for military operations: dense calories, low fiber (by design — they're literally constipating after a few days), expensive per meal, unfamiliar to your kids. A rotating pantry of normal staples beats an MRE stockpile on every metric except shelf life.
04
The toilet stops within two flushes of water loss. The twin-bucket system takes thirty minutes and fifty dollars to set up now. Set up during an actual outage, the same task is a miserable scramble.
05
A generator that's never been started. A camp stove still in the box. A radio nobody knows how to tune. The first time you operate a piece of equipment shouldn't be in the dark with rain coming sideways. Pull each item out once a year, fire it up, learn its quirks. Half an hour, well spent.
Cash & rotation
A two-week supply that sits untouched for a decade isn't a supply — it's a decaying museum. The households that actually have what they think they have are the ones that use it and replace it.
$500–$1,500 in small bills, stored somewhere accessible but not obvious. When ATMs and card readers go offline, this is the only way to pay for fuel, ice, or a place to stay. Mix denominations — making change is a problem when banks are closed.
First in, first out. New stock goes behind old stock. Dates on a Sharpie line across the lid. The pantry rotates the same way the milk in the fridge does — without ceremony, without thinking about it.
If you wouldn't cook with it on a Tuesday, don't store it for a hurricane. The rice in the bucket is the same rice you make for dinner. The pantry is just a deeper version of the kitchen.
One weekend a year — typically before hurricane season or before winter, depending on your region. Walk the supplies. Replace what expired. Refill what's run down. Most households need an hour and $50.
