Field Notes & Gear · September 2, 2026

Ten days without power is a different problem than an afternoon.

To prepare for an ice storm outage, plan for five days without power, not five hours. That means a heat source that does not need electricity, water stored before pipes freeze, a battery carbon monoxide alarm, lighting, and a way to get information when the internet is gone. In the South, ice storms cause longer outages than hurricanes because the damage is spread thin across thousands of miles of line instead of concentrated in one path.

Last January, up to 180,000 Mississippi customers lost power in a single weekend. Entergy Mississippi was still restoring the last few thousand homes on February 3 — ten days after the ice came down.

I don't say that to scare anybody. I say it because ten days is a different problem than an afternoon, and most people prepare for the afternoon.

What the forecast actually says about this winter

NOAA's Climate Prediction Center now puts the odds of a very strong El Niño above 90% for fall and winter 2026–27. There's a 69% chance the October–December stretch sets a record — stronger than any El Niño measured since 1950.

Here's what that means in plain terms. El Niño shifts the Pacific jet stream south. The storm track that normally runs across the northern states drops down over the southern tier. NOAA's confidence is highest for above-normal precipitation across the Gulf States and Southeast, and the wet signal is expected to ramp up late, peaking January through March 2027.

Now the honest part, because this is where most preparedness sites overreach.

El Niño does not forecast an ice storm. It tilts the odds toward a wetter southern winter and a warmer northern one. On average, El Niño winters in the Deep South run milder. The Climate Prediction Center is careful about this — even a record-strength event doesn't produce the textbook outcome everywhere.

What it does is load the moisture side of the equation. Ice storms need two ingredients: cold air, and rain falling through it. A wetter-than-normal winter doesn't guarantee the cold shows up. It means that if a cold outbreak does arrive, there's a lot more water available to freeze on your lines.

That's a reason to have a plan, not a reason to panic. Winter Storm Fern hit in a season nobody was watching.

Why ice storms hit the South harder

Vermont gets ice too. Vermont doesn't lose power for ten days.

Three things work against us down here. First, our distribution lines are overhead and they run through trees — pine, oak, pecan, all of it heavy-limbed and none of it built for a half inch of glaze. Second, vegetation management is a bigger job in a place where things grow year-round. Third, and this is the one people miss, utilities in the South don't get routine practice at ice restoration the way northern utilities do. Crews and equipment have to be borrowed.

Entergy pulled about 2,800 workers from more than twenty states and Canada to restore Mississippi in January. The damage tally in their service area alone: 234 broken poles, roughly 50 miles of downed wire, 35 damaged transformers, 107 broken cross arms.

That's not one path of destruction like a hurricane. That's thousands of small breaks scattered across the state, each one needing a truck to reach it, on roads that are still iced over.

This is the whole reason ice outages run long. Hurricane damage is concentrated and crews can work an assembly line. Ice damage is diffuse, and it keeps happening — Entergy reported new poles coming down days into the restoration as weakened trees kept failing.

How long do you actually need to plan for?

Outage lengthHow commonWhat it demands
Under 4 hoursRoutineFlashlights. Nothing else.
1–2 daysCommon in any ice eventHeat, water, food that needs no cooking
3–5 daysNormal for a moderate ice stormEverything above, plus sanitation and a way to charge devices
7–10 daysThe hardest-hit rural areasFull self-sufficiency; expect no store runs

Plan for five days. That's the number I'd give anybody in Mississippi, Louisiana, Alabama, Arkansas, Tennessee, or east Texas. Five days covers the overwhelming majority of real outages without going down the bunker rabbit hole. If you're on a rural line at the end of a long feeder, stretch it to seven.

Heat: the part that actually kills people

Cold is the danger. Everything else is inconvenience.

Never heat your home with an oven, a range, a charcoal grill, or a camp stove. Not with the windows cracked. Not for a few minutes. The CDC is unambiguous on this, and it's the single most common way people die in winter outages.

The CPSC reports that an average of nearly 100 Americans die each year from carbon monoxide poisoning caused by portable generators, and the majority of those deaths land between November and February. The pattern is always the same — the power goes out, it's cold, somebody brings the fuel-burning thing inside or too close, and CO builds up faster than anyone recognizes the symptoms.

What works instead:

A battery-operated CO alarm on every level, tested before winter

This is a twenty-dollar item that does more to keep you alive than anything else on this list. If you buy one thing after reading this, buy this. Note that you want a carbon monoxide alarm — not a carbon dioxide monitor, which is a different product sold for air quality and will not help you here.

GearBattery-operated carbon monoxide alarm →

An indoor-rated propane heater

The small radiant units with an oxygen depletion sensor and tip-over shutoff are legitimately designed for indoor use. The limits matter and the manufacturers say so plainly: you still need ventilation, they're not rated for sealed rooms or for sleeping unattended, and altitude and enclosure size both affect safe use. Read the actual manual, not a blog post about it. Mine included.

GearIndoor-safe radiant propane heater →

A wood stove or fireplace, if you have one

With the wood already split and dry. Green wood in January is a lesson you only need once. If you're weighing a stove as a primary heat source, the off-grid wood heat guide covers sizing, clearances, and seasoning in more depth.

Layers and a rated sleeping bag before you reach for any of it

A 20°F bag and wool socks let a family close off one room and ride out a cold night with zero fuel burned and zero risk. Consolidate everyone into the smallest room with the fewest exterior walls, hang a blanket over the doorway, and you've cut the space you're heating by eighty percent.

GearCold-weather sleeping bag →

This is general preparedness guidance and doesn't replace manufacturer instructions or advice from your local fire department.

Generator safety: the 20-foot rule and why it's not arbitrary

If you run a portable generator, the CDC and CPSC both say the same thing: outside only, at least 20 feet from any window, door, or vent, with the exhaust pointed away from the house.

Not the garage with the door open. Not the carport. Not the porch. Your house is not airtight, and pressure differences actively pull exhaust in through gaps you can't see.

The practical piece nobody mentions: 20 feet of distance requires more than 20 feet of cord. The CDC says this outright. If your only extension cord is a 15-footer, you will end up putting the generator where the cord reaches, and that decision gets made at 2 a.m. in the cold when you're not thinking well. Buy the cord in September.

GearHeavy-duty outdoor extension cord, 25 ft or longer →

Two more. Never backfeed a generator into a wall outlet — it can kill a lineman working to restore your street, and it needs a proper transfer switch installed by an electrician. And shut the generator down and let it cool fifteen or twenty minutes before refueling.

If you don't want to deal with fuel at all, a lithium power station covers the things that actually matter in a short outage — phones, a CPAP, a laptop, a lamp, a router if you still have service. It won't run a heater or a well pump, and anyone telling you otherwise is selling something. Match the watt-hours to what you actually need to run, not to the biggest number in the listing.

GearPortable lithium power station →

Water: the failure nobody plans for

Here's what happened in a lot of Mississippi homes in January. The power went out, the house got cold, the pipes froze, and then either the pipes burst or the municipal system lost pressure because half the town's pipes burst. People had generators and heaters and no water.

Fill containers before the storm, not during it. A bathtub liner bladder holds around 100 gallons and keeps it clean enough for flushing and washing. Jugs in the freezer do double duty — they hold cold in a dead freezer and they thaw into drinking water.

GearBathtub water storage bladder →

Before the cold arrives: cover outdoor faucets, insulate any pipe running through a crawlspace or exterior wall, and know where your main shutoff is. When a pipe does burst, the difference between a wet floor and a destroyed house is how fast you find that valve.

On well systems, no power means no pump. Store more, and see the off-grid well water guide for manual backup options.

Food and the freezer clock

The CDC's numbers are worth memorizing because they're counterintuitive:

ApplianceSafe window with the door closed
Refrigerator4 hours
Freezer, full48 hours
Freezer, half full24 hours

A full freezer holds cold twice as long as a half-empty one. If a storm is in the forecast, fill the empty space with jugs of water. It costs nothing and it buys you a day.

Perishables that sat above 40°F for four hours or more get thrown out. Don't taste-test it.

For eating: shelf-stable food you don't have to cook or add water to. Peanut butter, canned protein, crackers, dried fruit. A manual can opener, because the electric one is a doorstop. Nothing exotic — the goal is calories with zero infrastructure.

Light and information

Headlamps beat flashlights, because both hands stay free. One per person, plus spare batteries in a bag you can find in the dark.

GearLED headlamp →

Skip candles. House fires spike during outages, and the tradeoff isn't close.

For information, a hand-crank or battery NOAA weather radio works when the towers are down and your phone is dead. This is the piece most people skip and then wish they hadn't, because during Fern the useful information — road closures, warming center locations, restoration estimates — was moving faster than anyone's dying phone battery could keep up with.

GearNOAA weather radio, hand-crank or battery →

And the one people never think about until it's too late: when the power's out, your internet is out. Every how-to you bookmarked, every repair video, every first-aid reference lives on a server you can't reach. That's the whole reason GridDownData exists — the vault sits on a drive in your house and works whether the grid does or not.

The one-hour version

If you do nothing else, do these five things this month:

  1. Buy and test a battery CO alarm. Twenty dollars, ten minutes.
  2. Buy a 25-foot outdoor extension cord if you own a generator.
  3. Fill six one-gallon jugs and put them in the freezer. Free.
  4. Find your water main shutoff and make sure the valve turns.
  5. Pick your warm room — smallest, fewest exterior walls — and know where the blankets are.

That's an hour and about sixty dollars. It covers more real-world risk than a thousand-dollar generator sitting unfueled in the shed.

Frequently asked questions

How long do power outages last after an ice storm?

Most ice storm outages in the South run one to three days, but the hardest-hit rural areas can go a week or longer. After Winter Storm Fern in January 2026, Entergy Mississippi was still restoring customers on February 3 — roughly ten days after the storm. Plan for five days at minimum.

Why do ice storms cause longer outages than hurricanes?

Hurricane damage is concentrated along a path, so crews can work it systematically. Ice damage is scattered across thousands of individual break points — Entergy counted 234 broken poles and 50 miles of downed wire in Mississippi alone. Each repair needs a truck to reach it, over iced roads, and weakened trees keep falling for days afterward.

How far away does a generator need to be from the house?

At least 20 feet from any window, door, or vent, outdoors only, with the exhaust directed away from the structure. The CDC recommends using an extension cord longer than 20 feet so the distance is actually achievable. A garage with the door open is not safe.

How long does a freezer stay cold without power?

A full freezer holds safe temperatures for about 48 hours if you keep the door closed. A half-full freezer holds for about 24 hours. A refrigerator holds for about 4 hours. Filling empty freezer space with water jugs before a storm nearly doubles your window.

Is it safe to heat a house with the oven or a grill during an outage?

No. Never. Ovens, ranges, charcoal grills, and camp stoves all produce carbon monoxide and are not safe for heating indoors under any circumstances, including with windows open. The CPSC reports nearly 100 Americans die each year from generator-related CO poisoning alone, most of them between November and February.

Will the 2026–27 El Niño cause ice storms in the South?

Nobody can forecast a specific ice storm months out. What NOAA's Climate Prediction Center projects is a very strong El Niño — above 90% probability — that shifts the storm track south and favors above-normal precipitation across the Gulf States and Southeast. That raises the moisture available if a cold outbreak arrives. It is a shift in odds, not a prediction.

What should I do first if I'm starting from zero?

Buy a battery-operated carbon monoxide alarm and test it. It's the cheapest item on any preparedness list and the one that most directly keeps people alive during winter outages.

Do I need a generator to get through a winter outage?

No. A generator is convenient, not essential. Heat, water, food, light, and a CO alarm cover the actual risks. Plenty of people got through January in one warm room with sleeping bags and a propane heater, and did fine.
