Powerful winter storms that left hundreds of thousands of people across the U.S. without power for days in freezing temperatures in late January 2026 have been linked to more than , and the cold weather is forecast to continue into February.

The causes of the deaths and injuries have varied. Some people died from . Others fell outside or suffered . Three young brothers died after . Dozens of children were treated for from improperly used generators or heaters.

These tragedies and others share a common theme: Winter storms pose multiple dangers at once, and people often underestimate how quickly conditions can become life-threatening.

I’m the associate director of the at the University of South Carolina, where we work on ways to . Here is what people need to know to reduce their risk of injury during severe winter weather.

Prepare before the storm arrives

Preparation makes the biggest difference when temperatures drop, and services fail. Many winter storm injuries happen after power outages knock out heat, lighting or medical equipment.

Start by assembling a . The Federal Emergency Management Agency recommends having water, food that does not require cooking, a flashlight, a battery-powered radio, extra batteries and a first-aid kit, at minimum.

In wintertime, you’ll also need warm clothing, blankets, hats and gloves. When you go out, even in a vehicle, make sure you dress for the weather. Keep a blanket in the car in case you get stranded, as highway on Jan. 27 in freezing, snowy weather.

Portable phone chargers matter more than many people realize. During emergencies, for updates, help and contact with family. Keep devices charged ahead of the storm and conserve battery power once the storm begins.

If anyone in your home , make a plan now. Know where you can go if the power goes out for an extended period. Contact your utility provider in advance to ask about outage planning, including whether they offer for customers who rely on powered medical equipment.

What to do if the power goes out

Loss of heat is one of the most serious dangers of winter storms. Hypothermia can occur indoors when temperatures drop, especially overnight.

If the power goes out, choose one room to stay in and close its doors to keep the warmth inside. Cover windows with curtains or blankets. Wear loose layers and a knit hat to keep your own body heat in, even indoors. Remember to also eat regular snacks and drink warm fluids when possible, since the body uses energy to stay warm.

It might seem tempting, but don’t use camp stoves, outdoor grills or generators inside a home. These can , an odorless and deadly gas. During the January storm, one Nashville hospital saw with carbon monoxide poisoning linked to unsafe heating practices.

If you must use a generator, keep it outdoors and far from windows and doors. Make sure your home’s carbon monoxide detectors are working before storms arrive.

If your home becomes too cold, go to a warmer place, such as a friend’s home, a warming center or a public shelter. You can call 2-1-1, a nationwide hotline, to find local options. The and the also list open shelters on their websites. Several states maintain online maps for finding warming centers and emergency services during winter storms, including , , , , , and .

Be careful outside – ice changes things

Winter storms make everyday activities dangerous. Ice turns sidewalks into slippery hazards. Snow shoveling strains the heart. Frozen ponds and lakes might look solid but often are not as the ice can .

Walking on icy surfaces, even your own sidewalk, requires slow steps, proper footwear and full attention to what you’re doing. Falls can cause , and it can happen with your first step out the door.

Shoveling snow is a common risk that people often overlook, but it deserves special caution. The actions of shoveling in cold weather can place intense strain on the heart. For people with heart conditions, it that extra strain .

If you’re shoveling, take frequent breaks. Push snow instead of lifting when possible. And stop immediately if you feel chest pain, dizziness, or shortness of breath.

Communication saves time and lives

Winter storms disrupt information flows. Cell service fails. Internet access drops. Power outages silence televisions.

In my research on heat and storm emergencies, people frequently , resources, and safety information. With that in mind, check on family, friends and neighbors, especially older adults and people who live alone.

shows that nearby social ties matter during disasters because they help people share information and act more quickly when services are disrupted. Make sure that the information you’re sharing is coming from reliable sources – not everything on social media is. Also, let others know where you plan to go if conditions worsen.

Use multiple sources for information. Battery-powered radios remain critical during winter storms. Sign up for local emergency alerts by email or text. that in regions accustomed to frequent hazardous weather, people often take actions in response to risks more slowly when they don’t have reliable local updates or clear alerts.

Practice matters

Many injuries happen because people delay actions they know they need to take. They wait to leave a house that’s getting too cold or at risk of damage by weather, such as flooding. They wait to ask for help. They wait to adjust plans.

In research I contributed to on evacuation drills involving wildfires, people who were more likely to react quickly when conditions changed. for any type of emergency, whether a hurricane or a winter storm, builds people’s confidence and reduces their hesitation.

Take time each winter to review your emergency supplies, communication plans, and heating options.

Winter storms will test your preparation, judgment, and patience. You cannot control when the next one arrives, but you can decide how ready you will be when it does.
