Winter storms in Great Falls, Montana, can create much more than inconvenience. Heavy snow, freezing temperatures, strong winds, icy roads, power outages, and prolonged travel disruptions can produce serious health risks for residents of all ages. Montana's winter storm guidance specifically identifies hypothermia, frostbite, carbon monoxide poisoning, accidents, and heart attacks related to overexertion as potential hazards during severe winter weather.

For people living in Great Falls, winter health preparedness means thinking beyond warm clothing and snow tires. A storm can affect access to medications, delay emergency transportation, interfere with medical appointments, increase the physical demands of snow removal, and leave people isolated inside their homes for days. Older adults, young children, people with heart or lung conditions, people with limited mobility, and anyone who relies on regular prescription medications may face additional challenges.

Understanding these risks before a storm arrives can help residents make safer decisions. If you have a heart condition, check the Great Falls winter storm warning today before deciding whether to shovel — during an active warning, heavy wet snow combined with cold air can make strenuous outdoor work particularly dangerous.

Heart Attack Risk From Snow Shoveling

Snow shoveling is one of the most overlooked winter health hazards. It may appear to be a routine household chore, but clearing a driveway or sidewalk can become vigorous cardiovascular exercise, especially when snow is deep, wet, or packed with ice. Cold weather also places additional demands on the cardiovascular system. Montana emergency preparedness guidance recommends avoiding overexertion while shoveling and walking in snow because of the potential for serious cardiovascular consequences.

The risk can be particularly concerning for people with known heart disease, high blood pressure, diabetes, high cholesterol, or a history of heart attack or stroke. People who are normally sedentary may also be at greater risk when they suddenly perform strenuous activity during a storm.

Cold temperatures can cause blood vessels to constrict, which can increase blood pressure. At the same time, pushing a heavy shovel through snow increases the heart's workload. Breathing cold, dry air can add another challenge, particularly for people with cardiovascular or respiratory conditions. The combination of cold exposure and sudden exertion is why snow removal should not automatically be treated as harmless exercise. The CDC advises people with heart disease or high blood pressure to follow their doctor's advice about shoveling and to avoid excessive exertion in cold weather.

Residents should consider asking someone else to handle heavy snow removal if they have been advised to avoid strenuous activity. If shoveling is necessary, use a smaller load, take frequent breaks, dress in layers, and avoid trying to clear everything at once.

Never ignore warning symptoms. Chest pressure or pain, unusual shortness of breath, severe weakness, cold sweating, nausea, or pain spreading to the arm, shoulder, back, neck, or jaw can be signs of a heart attack. Call 911 rather than attempting to drive yourself to the hospital.

Recognizing Hypothermia During a Great Falls Winter Storm

Hypothermia occurs when the body loses heat faster than it can produce it. Although it is most likely during very cold conditions, it can occur in less extreme temperatures when a person becomes wet, sweaty, or exposed for an extended period. The CDC defines a dangerously low body temperature as below 95°F and considers hypothermia a medical emergency.

Early symptoms can include shivering, fatigue, clumsiness, and difficulty concentrating. As the condition progresses, a person may become confused, have trouble speaking, fumble with objects, experience memory problems, become extremely drowsy, or lose coordination. In severe cases, shivering may stop as body temperature continues to fall, and breathing and pulse can slow.

This progression is important because a person experiencing hypothermia may not recognize how serious the situation has become. Confusion can make it difficult for them to seek help or make sensible decisions. Family members, neighbors, and caregivers should therefore pay particular attention to people who live alone during prolonged storms.

If you suspect hypothermia, move the person into a warm, dry environment and remove wet clothing. Warm the center of the body, particularly the chest, neck, head, and groin, using dry blankets or appropriate warming methods. If the person is alert and able to swallow safely, a warm nonalcoholic drink may help. Do not give anything by mouth to someone who is unconscious or unable to swallow normally. Seek medical attention immediately, particularly when body temperature is below 95°F or serious symptoms are present.

Frostbite: Symptoms and Proper Treatment

Frostbite happens when body tissue freezes. It most commonly affects exposed or poorly protected areas such as fingers, toes, ears, nose, cheeks, and chin. Early symptoms can include redness, pain, tingling, or numbness. More advanced frostbite may cause the skin to appear white, grayish-yellow, or unusually firm and waxy.

Numbness can make frostbite especially dangerous because a person may not realize how much damage has occurred. Someone working outside to clear snow may continue for longer than is safe because the affected area no longer hurts.

If frostbite is suspected, get out of the cold and seek medical care. If immediate medical care is unavailable and there are no signs of hypothermia, the affected area can be gently rewarmed in warm, not hot, water. The water should feel comfortably warm to unaffected skin. Body heat can also be used for areas such as fingers.

Do not rub or massage frostbitten skin, and do not rub it with snow. Avoid heating pads, heat lamps, fireplaces, radiators, or other intense direct heat because numb tissue can burn without the person realizing it. The CDC also advises avoiding unnecessary walking on frostbitten feet or toes because walking can increase tissue damage.

Frostbite should be evaluated by a healthcare professional. Severe frostbite can cause permanent tissue damage and, in extreme cases, may result in the loss of affected tissue.

Carbon Monoxide Poisoning From Generators and Blocked Vents

Carbon monoxide, or CO, is one of the most dangerous indoor hazards associated with winter storms. It is colorless and odorless, so people cannot rely on their senses to detect it. Portable generators, fuel-burning appliances, charcoal grills, and other combustion sources can produce CO.

Generators are particularly dangerous when residents use them inside homes, garages, basements, sheds, or other enclosed spaces. Opening a garage door or window does not make indoor generator use safe. The CDC recommends operating portable generators outdoors and more than 20 feet from windows, doors, and vents. Homes should also have battery-powered or battery-backup carbon monoxide detectors.

Blocked vents and chimneys are another winter concern. Heavy snow, ice, or debris can interfere with the normal ventilation of fuel-burning heating equipment. When combustion gases cannot escape properly, CO can accumulate indoors.

Symptoms of carbon monoxide poisoning can resemble the flu. Headache, dizziness, weakness, nausea, vomiting, chest pain, confusion, and unusual sleepiness are common warning signs. More serious exposure can result in unconsciousness, neurological injury, heart complications, or death.

If a carbon monoxide alarm sounds, or if several people in the same building suddenly develop unexplained flu-like symptoms, get outside into fresh air and call 911. Do not remain indoors trying to identify the source yourself. People who are sleeping, very young, elderly, or medically vulnerable can be particularly susceptible to serious poisoning.

Seasonal Affective Disorder During Prolonged Winter Storms

Winter storms can affect mental health as well as physical health. A major storm may keep people indoors for extended periods, interrupt normal routines, cancel social activities, and reduce exposure to daylight. For some people, repeated winter isolation can contribute to worsening mood or symptoms of seasonal affective disorder, commonly known as SAD.

Seasonal affective disorder is a form of depression that follows a seasonal pattern in some people. Symptoms may include persistent sadness, low energy, loss of interest in normal activities, changes in sleep, changes in appetite, difficulty concentrating, and social withdrawal.

A single storm does not necessarily cause SAD, but prolonged periods of reduced daylight and isolation can make existing mental health challenges more difficult. Residents can reduce some of the effects by maintaining a regular sleep schedule, staying physically active indoors, opening curtains or blinds during daylight hours, maintaining social connections by phone or video, and keeping a predictable daily routine.

People who experience persistent or severe depression should speak with a qualified healthcare professional. Anyone experiencing thoughts of suicide or immediate danger should seek emergency assistance rather than waiting for the storm to end.

Pharmacy Access When Roads Are Closed

Medication access can become a major health issue during a Great Falls winter storm. Icy roads, poor visibility, road closures, transportation problems, and business closures can prevent residents from reaching a pharmacy when they need a prescription refill.

This is especially important for medications that should not be stopped suddenly. People who take medicines for heart conditions, diabetes, asthma, seizure disorders, blood pressure, or other chronic conditions should avoid waiting until the last dose before arranging a refill.

Before major winter weather arrives, check your medication supply and contact your pharmacy if you are approaching a refill date. Ask whether the pharmacy offers delivery, whether prescriptions can be transferred when appropriate, and what procedures apply during severe weather. If you use multiple medications, maintaining an updated medication list can also help emergency healthcare workers understand what you take if you become ill.

Keep medications stored according to their specific instructions. Some medicines can be damaged by freezing temperatures, while others have special storage requirements. If a power outage affects a medication that normally requires refrigeration, contact your pharmacist or healthcare provider for specific guidance rather than guessing about whether it remains safe.

It is also wise to keep important healthcare information accessible even if internet or cellular service becomes unreliable. A written list containing medication names, doses, allergies, medical conditions, emergency contacts, and healthcare provider information can be useful during an extended storm.

Hospital Emergency Preparedness in Great Falls

Winter storms can increase demand for emergency medical services while simultaneously making transportation more difficult. Hospitals and healthcare systems must prepare for injuries from falls, traffic collisions, cold exposure, cardiac emergencies, carbon monoxide poisoning, respiratory problems, and complications among patients whose routine medical care has been disrupted.

Montana's Department of Public Health and Human Services maintains public health emergency preparedness and healthcare preparedness programs designed to strengthen emergency readiness across the state. These programs work with healthcare and public health partners to prepare for emergencies that can disrupt normal services.

For residents, hospital preparedness is only one part of the equation. Individuals should also understand when a situation requires emergency care. A winter storm should never be a reason to delay treatment for a potentially life-threatening condition. Severe chest pain, difficulty breathing, unconsciousness, severe confusion, suspected carbon monoxide poisoning, severe hypothermia, serious frostbite, uncontrolled bleeding, or other major emergencies warrant immediate medical attention.

At the same time, residents can help emergency services by avoiding unnecessary travel during dangerous conditions. If an injury is minor and can safely be managed at home, contacting a healthcare provider, pharmacist, or appropriate medical advice service may be preferable to traveling during the worst conditions. But this should never override the need for emergency care when serious symptoms are present.

Who Faces the Greatest Risk During Winter Storms?

Cold-weather health risks do not affect everyone equally. Older adults may have difficulty maintaining body temperature or may live alone. Infants and young children lose heat more quickly and depend on adults for appropriate clothing and shelter. People experiencing homelessness face prolonged outdoor exposure. Individuals with heart, lung, circulation, or other chronic conditions may have greater difficulty coping with extreme cold.

People with limited mobility can face additional challenges if sidewalks, driveways, or building entrances become covered with snow and ice. Those who depend on home healthcare, oxygen equipment, electrically powered medical devices, or regular transportation may also need a specific storm plan.

Neighbors can play an important role. During a prolonged storm, check on older relatives, friends, and vulnerable neighbors by phone or in person when conditions are safe. Make sure they have adequate heat, food, medications, and a way to request assistance.

How Great Falls Residents Can Reduce Winter Health Risks

The safest approach is to prepare before severe weather arrives. Keep several days of essential medications and basic medical supplies available when possible. Maintain working smoke and carbon monoxide alarms. Know how to operate heating equipment safely. Keep warm clothing, blankets, flashlights, food, water, and communication equipment accessible.

Plan alternatives for essential medical transportation before roads become hazardous. If you have a chronic medical condition, discuss winter activity limitations with your healthcare provider before the season becomes severe. Know the symptoms that should prompt an emergency call rather than waiting for conditions to improve.

During the storm, stay indoors whenever possible. Avoid unnecessary snow shoveling and heavy outdoor work. If you must go outside, wear multiple insulating layers, keep hands and feet protected, avoid getting wet, and take regular warming breaks. Pay attention to shivering, numbness, confusion, unusual fatigue, or changes in coordination.

After the storm, remember that health risks do not immediately disappear when snowfall stops. Snow removal can remain physically demanding, icy sidewalks can cause falls, and generators may continue operating during power outages. Check outdoor vents and heating equipment for snow blockage, but do so safely. Continue monitoring vulnerable family members and neighbors until normal heating, transportation, pharmacy access, and medical services have resumed.

Final Thoughts

Winter storms in Great Falls can create a chain of health hazards that extends well beyond cold temperatures. Snow shoveling can place significant strain on the heart, prolonged exposure can cause hypothermia and frostbite, improperly operated generators can produce deadly carbon monoxide, and extended isolation can affect mental health. Road closures can also interfere with access to pharmacies, medical appointments, and emergency services.

The most effective protection is preparation combined with good judgment. Know when outdoor activity is unsafe, recognize early symptoms of cold-related illness, use generators and heating equipment correctly, maintain access to essential medications, and seek emergency care when serious symptoms occur. By planning ahead and respecting the hazards created by severe winter weather, Great Falls residents can reduce preventable injuries and protect their health throughout Montana's challenging winter season.
