Winter Power Outage Prep: A Family Guide for Every Zone

Picture a winter evening. Maybe snow is blowing sideways past the window, maybe freezing rain is ticking on the glass, or maybe the wind is roaring in off the coast. The lights blink twice, and then the house goes quiet. For a second nobody says anything. Then the youngest whispers, "Is this a blanket-fort night?"

And it is. Every quilt in the house ends up in the living room. A lamp glows from the power station in the corner, hand warmers get passed around, and the radio murmurs the weather update while the wind does its thing outside. Years from now, that's the night the kids will remember. Not because it was scary, but because everyone was together, warm and close.

That calm doesn't happen by accident. It comes from a little planning done on an ordinary afternoon. Winter outages happen in every kind of climate: blizzards where winters run long, ice storms where freezing rain is common, surprise hard freezes where winters are usually mild, and wind and rain storms near the coast. Most outages are short; some last a day or more. Here's how to get your home and family ready wherever you live, starting with your winter zone.

First, the cautions everyone should know

Before any gear, a few widely shared guidelines from the CDC and fire departments:

• Never use a grill, camp stove, outdoor heater or generator indoors or in a garage, even with the door open. They give off carbon monoxide (CO), a gas you can't see or smell.
• Run generators outdoors only, at least 20 feet from doors, windows and vents, with the exhaust pointed away from the house.
• Never heat your home with a gas oven or stovetop.
• Install battery-powered or battery-backup CO alarms on every level and near bedrooms. Test them, and change the batteries when the clocks change.
• If a CO alarm sounds, or anyone feels dizzy, headachy or sick to their stomach, get everyone outside into fresh air right away and call 911.
• If you use a space heater, choose one made for indoor use, keep it 3 feet from anything that can burn, plug it straight into the wall, and never leave it running unattended or while you sleep.

Find your winter zone

Winter looks different depending on where you live, so start by finding your zone. A handy way is the USDA Plant Hardiness Zone Map (planthardiness.ars.usda.gov). Type in your ZIP code and it shows your zone, which is based on how cold your coldest winter nights usually get. Lower numbers mean colder winters. Elevation matters too: a mountain town can be in a much colder zone than the valley below, so go by your ZIP, not just your state. The zone ranges below are rough guides.

Severe Cold (roughly zones 3–5: long, deep-freeze winters and high-elevation areas) - Your biggest job is staying warm through long, very cold outages: plan your warm room, layers and sleeping warm first. - In a house without heat, pipes can freeze quickly, so learn the pipe steps below before winter. - Keep snow cleared from furnace, dryer and generator exhaust vents. - Keep a winter car kit in every vehicle.

Cold & Ice Storm (roughly zones 6–7: cold winters with frequent freezing rain) - Ice weighs down trees and lines, so outages can be widespread. Charge everything as soon as freezing rain is in the forecast. - Stay well away from downed lines and report them to your utility. - Ice makes roads treacherous, so plan to stay home for a day or two. - Follow the pipe steps on the coldest nights.

Mild with Surprise Freezes & Ice (roughly zones 8–9: usually mild winters with the occasional hard freeze) - Many homes here aren't built for hard freezes: pipes may run through outside walls, attics or crawlspaces with little insulation. Wrap exposed pipes and outdoor faucets before a cold snap, drip faucets and open the cabinets. - Fewer families keep winter gear, so set aside warm layers, hats and extra blankets now. - With fewer plows and salt trucks, icy roads can last a while. Stock a few days of food and water. - After a big freeze, water systems can be strained, so keep stored water and follow any local water notices.

Mild & Coastal (roughly zones 8–10 and up: mild, dry or coastal climates) - Winter wind and rain storms can bring down trees and power lines. - In wildfire-prone areas, some utilities turn off power ahead of high winds (often called Public Safety Power Shutoffs). Sign up for your utility's alerts, and plan backup power for phones, the fridge and any powered devices. - Desert and high-elevation nights can get colder than you'd expect, so keep warm layers handy. - Nearby mountain areas can be Severe Cold zones. Check your ZIP.

Wherever you live, the steps below work for every zone. Just adjust how much you plan for: more warmth in colder zones, more pipe protection where homes aren't built for freezes, more backup power where outages come with wind.

Step 1: The 15-minute "storm's coming" routine

When a winter storm is in the forecast, take a few minutes to:

1. Charge everything: phones, power banks, hand warmers, vest batteries and your power station.
2. Gather flashlights or headlamps in one easy-to-find spot.
3. Fill a few pitchers or jugs with water.
4. Fill the car's gas tank.
5. Save your utility's outage line or app on every phone.
6. Check that your CO and smoke alarms are working.

Step 2: Choose a warm room

Most furnaces, even gas ones, need electricity for the blower and igniter, so when the power goes, the heat usually goes too. A well-insulated home holds its warmth for a while, but plan ahead:

• Pick one interior room with few windows and bring the family (and pets) there.
• Close the doors to unused rooms. Hang a blanket over open doorways and roll towels against drafty door bottoms.
• Close the curtains at night, and open the sunny ones during the day.
• A few people sharing one small room makes a real difference. It's also where the stories and card games happen.

Step 3: Dress everyone in layers, then add personal warmth

It's much easier to stay warm than to get warm again, so layer up early.

• Layers: a base layer that wicks, a warm middle layer (fleece or wool) and a cozy outer layer. Hats indoors look silly and feel wonderful. Wool socks for everyone.
• Rechargeable hand warmers: the POWERPAW 501 heats up in under a minute and has four settings from 100°F to 125°F. The slim POWERPAW 502 slips into a pocket and runs about 6 hours on low. Both replace a drawer full of single-use packets.
• Heated vests: the Gobi Heat Dune vest, in women's and men's cuts, gives up to 10 hours of warmth from a compact rechargeable battery. It's just as handy for school pickup and the walk to the train.
• At night: sleeping bags or extra comforters, with blankets under you as well as on top.

Step 4: Light and news, without candles

• One light per person: a flashlight or headlamp each, so nobody has to share in the dark. Skip candles if you have kids or pets. (Options: the flat, rechargeable FLATEYE FR-500 or the hands-free POWERCAP 2.5 headlamp beanie.)
• A radio that doesn't need the wall: the Preppi Solar Phone Charger & Emergency Radio has weather-band, AM and FM radio, an LED flashlight and a USB port for topping up a phone. It recharges by solar panel or hand crank.
• Make it gentle for kids: glow sticks and a "flashlight captain" job turn a dark house into an adventure.

Step 5: Backup power for the things that matter

If an outage would be more than an inconvenience (you work from home, have a baby, or rely on powered devices), consider a portable power station. Unlike a gas generator, a battery power station is quiet and gives off no exhaust, so it can be used indoors.

The Jackery Explorer 1000 v2 stores 1,070Wh with 1,500W of output and uses long-life LiFePO₄ cells. That's enough to run lamps, charge phones and laptops, keep the modem and router on, or power a small appliance for a while. It can also recharge from compatible solar panels during the day. Just need phones, a lamp and the router? The smaller Jackery Explorer 300D (288Wh) is a lighter option.

Quick sizing tip: list what you'd want to run and add up the watts. Runtime is roughly the capacity in Wh, divided by the device's watts, times 0.85. A router, a few LED lamps and phone charging use very little. Space heaters use a lot, so plan on layers rather than electric heat. If a medical device needs power, check its maker's specs and talk with your provider about a backup plan.

Step 6: Protect your pipes

This matters in every zone, and especially in milder ones, where pipes are often less protected from the cold.

• Open the cabinet doors under sinks on outside walls.
• Let faucets drip slightly on the coldest nights.
• Know where your main water shut-off valve is before you need it, and show everyone in the house.
• If the outage drags on and the house gets very cold, call a plumber about draining your lines.

Step 7: Food and water for a few cozy days

• Keep the fridge and freezer closed. According to the USDA, a closed fridge keeps food cold for about 4 hours, and a full freezer about 48 hours.
• Use a thermometer. Food in the fridge should stay at 40°F or below. When in doubt, throw it out.
• Have a no-cook menu: peanut butter and crackers, granola, canned fish, fruit cups, shelf-stable milk, and a few treats for the kids. Fill thermoses with hot water or soup before the storm hits.
• Water: store at least 1 gallon per person per day, plus water for pets. If your home uses an electric well pump, an outage means no running water, so plan for it.
• Hot meals: cook outdoors only, well away from doors and windows. Coming soon: our Portable Steel Rocket Stove, which cooks with twigs and small sticks. Follow @ark.prep on Instagram to hear when it's back.

Step 8: Make it a family plan, and include your neighbors

Take ten minutes at dinner this week to talk through:

• Where the flashlights, radio and warm layers live
• Which room is your warm room
• Who checks on older neighbors or relatives nearby
• Where you'd go if your home got too cold (a friend's place or a warming center; your city or county emergency management office, or 211, can usually tell you what's open)
• How to report an outage to your utility

If you'd rather start with a shortcut, the Preppi GoBox 3-Day Emergency Kit packs 3 days of food and water, a flashlight, a mylar blanket and first-aid supplies into a box the size of a book. The GoBox Family Emergency Pack bundles kits for the whole household.

Your winter outage checklist

• ☐ CO alarms on every level and near bedrooms, tested
• ☐ A flashlight or headlamp for each person
• ☐ A weather-band radio with solar or crank charging
• ☐ Charged power banks, plus a power station if you need one
• ☐ Rechargeable hand warmers and heated vests
• ☐ Layers, wool socks, hats, sleeping bags and extra blankets
• ☐ A warm room chosen, with towels for door drafts
• ☐ 3+ days of no-cook food, plus water (1 gallon per person per day)
• ☐ Thermoses and an appliance thermometer
• ☐ Main water shut-off located and labeled
• ☐ Utility outage line saved; warming center info handy
• ☐ A neighbor check-in plan

Start small, start this week

You don't need everything at once. Pick one thing this week, maybe a hand warmer for each coat pocket or a radio for the kitchen shelf, and add one more next week. By the first big storm, your home will be ready for a blanket-fort night instead of a stressful one.
