Ice Storm Preparation: How to Protect Your Home and Family When Freezing Rain Hits

Snow is a nuisance. Ice is a different animal. A coating of freezing rain can snap tree limbs, pull down power lines and turn every road and sidewalk into a skating rink. Good ice storm preparation focuses on the two things ice does best: knocking out power for days and making it unsafe to leave the house.

This guide explains what makes ice storms so disruptive, then walks through the steps that matter most for your home, your power and your family’s safety.

Why ice storms cause so much damage

The National Weather Service defines freezing rain as rain that falls as a liquid but freezes into a glaze when it hits the ground or other surfaces. That glaze builds up on everything: branches, wires, cars and steps.

It doesn’t take much. The NWS usually issues an Ice Storm Warning for ice accumulation of around 1/4 inch or more. According to the NWS, heavy ice accumulations can bring down trees and topple utility poles and communication towers, and ice can disrupt communications and power for days while utility companies repair extensive damage.

That’s the key point for ice storm preparation: plan for a multi-day power outage, not a few hours.

Ice storm preparation for your home

Ice storm preparation starts with the trees

Falling limbs are the biggest threat to your roof, your car and the lines feeding your house. The CDC recommends cutting away tree branches that could fall on your home or other structures during a storm. Do it in the fall. Never try to trim branches near power lines yourself; call your utility.

Protect your pipes

A long outage in freezing weather can freeze pipes. The CDC recommends insulating water lines that run along exterior walls. When a storm hits, the Red Cross suggests opening cabinet doors under sinks so warm air can reach the pipes and letting cold water drip from faucets served by exposed pipes.

Stock salt and sand

Keep a bag of ice melt or sand by the door so you can make a safe path to the car or mailbox. Put it out before the freezing rain starts if you can.

Plan for days without power

Because ice storms are so hard on power lines, your outage plan is the heart of your ice storm preparation. Cover heat, food, water, light and power. If you’ve already built a power outage emergency kit, review it now and add the winter items below.

Heat one room safely

Pick an interior room, close it off from the rest of the house, and gather there. The CDC recommends stuffing towels in the cracks under doors and covering windows with blankets at night.

Never use a gas stove or oven for heat, and never bring a grill, camp stove or generator indoors. A non-electric heater rated for indoor use is the safer route. The VESTA Self-Powered Indoor Space Heater & Stove runs on InstaFire canned heat with no electricity, warms spaces up to about 200 square feet, and also works as a stove. The maker says to use it with adequate ventilation, and you should still run a battery-powered carbon monoxide detector. Our safe indoor non-electric heater guide covers more options.

Food that doesn’t depend on the fridge

Ready.gov says a refrigerator keeps food cold for about 4 hours and a full freezer for about 48 hours if you keep the doors closed. After that, perishable food that has been at 40°F or higher for two hours or more should be thrown out.

So stock food that stores at room temperature. The 1-Week Food Supply Ammo Can provides 14,860 calories (one person for a week, or two people for 72 hours) and has a shelf life of up to 25 years when stored properly. For a larger household, the 4-Week Emergency Food Supply feeds a family of four for one week. Both need water and heat to prepare, so plan for both.

Water

Ready.gov recommends one gallon per person per day for several days, for drinking and sanitation. If you’re on a well, remember that an electric pump stops when the power does, so fill containers before the ice arrives.

Backup power for what matters most

Decide what you truly need to run. For phones, lights, a router or a CPAP machine, the Grid Doctor 300 Solar Generator offers a 320Wh battery and 300W output with a 100W solar panel. It’s not designed for a full-size fridge.

If keeping the refrigerator running through a multi-day ice storm is a priority, the Grid Doctor 3300 Solar Generator is the one sized for that job. It has 3300W continuous output and a 2048Wh battery (expandable to 16,384Wh), and the maker specifically lists ice storms and multi-day outages with refrigeration among its uses. Our Grid Doctor 300 vs 3300 comparison breaks down which one fits your home.

If you use a gas generator instead, run it outdoors only, at least 20 feet from windows, doors and attached garages (Ready.gov).

Staying safe during and after the ice storm

Ice storm preparation doesn’t end when the freezing rain starts. These steps keep your family safe until the ice melts.

Stay off the roads

Ice makes driving dangerous. The CDC advises avoiding ice-covered roads, overpasses and bridges, and Ready.gov says to stay off the roads if possible. If you must go, keep a winter kit in the car and let someone know your route.

Stay away from downed lines

OSHA advises assuming all power lines are energized and staying clear of any downed or damaged line. A line on the ground can still be live even if it isn’t sparking. Report downed lines to your utility or 911, and keep kids and pets away from fallen branches that may be touching wires.

Walk carefully

Slips on ice are a real risk for anyone, especially older adults. Wear boots with good tread, use your salt or sand, and take short steps. Check on older neighbors so they don’t have to go out.

Watch for carbon monoxide

Long outages tempt people to improvise heat. The CDC says more than 400 Americans die each year from unintentional carbon monoxide poisoning not linked to fires. Symptoms include headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion. The CPSC says never to ignore a CO alarm: get outside immediately, then call 911.

Ice storm preparation checklist

• Trim branches near the house in the fall
• Test smoke and CO alarms; keep spare batteries
• Insulate exposed pipes; know where your main water shutoff is
• Several days of no-refrigeration food and water per person
• Safe indoor heat for one room
• Flashlights, lantern, NOAA Weather Radio and batteries
• Charged power banks or a solar generator
• Ice melt or sand, and boots with good tread
• Full gas tank and a winter car kit
• Medicines and a plan for any powered medical devices

Frequently asked questions

How much ice does it take to cause power outages?

The NWS usually issues an Ice Storm Warning for about 1/4 inch of ice or more. Heavy accumulations can topple utility poles and keep power out for days.

What is the most important part of ice storm preparation?

Planning for a multi-day power outage in the cold: safe heat, food that doesn’t need the fridge, water and light. Trimming trees near your home in the fall comes a close second.

Should running faucets be part of ice storm preparation?

The Red Cross suggests letting cold water drip from faucets served by exposed pipes when it’s very cold. Running water, even at a trickle, helps prevent freezing.

Is it safe to drive after an ice storm?

Wait if you can. Roads, bridges and overpasses can stay icy long after the freezing rain stops, and downed trees and lines may block routes.

The bottom line

Ice storm preparation is really outage preparation with a few winter extras. Trim the trees, protect the pipes, plan safe heat for one room, and stock enough food, water and power to get through several days. Then stay home and let the crews do their work.
