Essential warmth: Blankets & emergency heaters

Staying warm can be a matter of survival. Having the right tools, like blankets and emergency heaters, is important. When you’re stranded in your car during a winter storm, the cold can quickly become a serious threat. 

Blankets

An effective and immediate way to combat the cold is with a high-quality blanket. Wool blankets are a top choice because they provide excellent insulation and remain warm even when damp. Synthetic blankets are another great option. They are lightweight, easy to store, and offer moisture resistance, which is crucial in wet or snowy conditions.

Heaters

In addition to blankets, an emergency heater can be a lifesaver. However, it’s important to choose a battery-operated model to ensure safety. Propane or fuel-based heaters can produce dangerous levels of carbon monoxide, which can be fatal in an enclosed space. 

Battery-operated heaters, on the other hand, are safe to use inside your car. They can provide a reliable source of heat without the risk of poisoning. They are also easy to operate and can be a valuable addition to your emergency winter supply kit.

Hand warmers

Hand warmers are another essential item that should be included in your emergency winter supply kit. These small, portable packets can be activated to provide several hours of warmth. This makes them ideal for quick relief when you need it most. 

Whether you’re trying to keep your hands warm to operate a mobile device or simply need to maintain your body temperature, hand warmers are a must-have. They are lightweight, take up minimal space, and can be easily stored in your glove compartment or emergency winter supply kit.

Extra clothing

To further ensure your comfort and safety, it’s important to store extra clothing layers in your car. Layers are key to managing your body temperature. Having additional socks, gloves, and a warm hat can make a significant difference. Wool and synthetic materials are particularly effective, as they insulate well and wick away moisture, keeping you dry and warm. 

Visibility & safety: Ice scraper & snow brush

Visibility is key during the icy season, and an ice scraper and snow brush are your first line of defense against the elements. Before you hit the road, it’s crucial to ensure that all your windows are free from frost, ice, and snow. 

Clearing your windshield and windows is not just about maintaining a clear view. It’s about ensuring your safety and the safety of others on the road. Failing to clear your windows can lead to reduced visibility, which increases the risk of accidents, especially in winter storms.

Use a snow brush for the rest of the car

A good snow brush is essential for removing heavy snow from the roof, hood, and trunk of your vehicle. While it might seem like an inconvenience, neglecting to clear these areas can have serious consequences. 

Snow on the roof can slide down and obstruct your view while driving. Snow on the hood can melt and refreeze on your windshield, creating a dangerous layer of ice. Using a snow brush ensures that your car is not only safe to drive, but also complies with local laws that require vehicles to be free of snow and ice.

Scrape ice from windshield & windows

An ice scraper is another indispensable tool for any driver. It’s not enough to just clear the snow. You need to remove any frost or ice that has accumulated on your windows and mirrors. A high-quality ice scraper with a sturdy handle and a sharp edge will make this task much easier. 

It’s important to keep an ice scraper and snow brush in your emergency winter supply kit so that you’re always prepared, no matter where you are. Regularly check and replace these tools to ensure they are in optimal condition. A worn-out scraper or a broken brush can leave you stranded and vulnerable in harsh winter conditions.

Traction & mobility: Sand or cat litter

When roads turn treacherous, a bag of sand or cat litter can be your unexpected hero, providing the traction you need to stay mobile. 

During winter driving, icy conditions can make it difficult for your vehicle’s tires to grip the road, leading to skidding and loss of control. Sand is a classic solution for this problem. When you sprinkle sand around your tires, it creates a gritty surface that enhances traction, helping your car gain the necessary grip to move safely. This is particularly useful when you’re stuck in a snowbank or on a slippery hill.

Cat litter is another option

Cat litter, on the other hand, offers a unique advantage due to its absorbent properties. The clay in cat litter can absorb moisture and form a more stable surface under your tires. This makes it especially effective in snowy conditions, where it can help melt a thin layer of ice and create better traction. 

Both sand and cat litter should be kept in easily accessible locations in your car. A trunk storage bin or a dedicated compartment can ensure that these items are ready when you need them most.

Keep a shovel in your emergency kit

To maximize the effectiveness of sand or cat litter, it’s a good idea to keep a small shovel in your emergency winter supply kit. A shovel can help you clear snow and ice from around your wheels, making it easier to apply the sand or cat litter where it’s needed most. This combination of tools can significantly improve your chances of getting your vehicle moving again in challenging winter conditions. 

Additionally, storing these supplies in a durable container will prevent spills and maintain organization, ensuring that everything is in good condition when you need it.

Nutrition & hydration: Non-perishable snacks & water

Keeping your energy up and your body hydrated is vital, so stock up on non-perishable snacks and plenty of water. 

During long waits in cold conditions, your body burns more calories to stay warm, and it’s crucial to maintain your energy levels. High-energy snacks like granola bars are perfect for quick calorie intake. They are compact, easy to store, and provide a quick boost when you need it most.

Always have water in your kit

Water is just as important as food, especially in cold weather. Dehydration can occur even in cold conditions, and it’s easy to overlook the need for water when it’s not hot outside. Keep a supply of bottled water in your emergency winter supply kit. 

Aim for at least one bottle per person, and more if you have room. Water should be stored in airtight containers to protect it from moisture and temperature changes, ensuring it remains safe to drink.

If your emergency winter supply kit includes canned goods, don’t forget to include a manual can opener. In a situation where you might not have access to electricity, a manual can opener is essential for accessing the food you’ve stored. This small but crucial item can make a big difference in your ability to stay nourished during a winter emergency.

Communication & Navigation: Charged Mobile Device & Portable Charger

In an age where we rely heavily on technology, a charged mobile device and a portable charger can be your lifeline in emergencies. 

During winter driving conditions, a fully charged phone is essential for staying connected with emergency services, family, and friends. It’s not just about making calls; your mobile device can also provide crucial navigation assistance, helping you find the safest and most efficient routes, even in the midst of a winter storm.

A portable charger is a small but vital component of your emergency winter supply kit. It ensures that your mobile device remains functional throughout your journey. Look for a charger with a high capacity and multiple charging ports, so you can keep your phone and other devices powered up simultaneously.
