Quick Answer
If you're stranded in your vehicle during a snowstorm, look for situational signs like intense snowfall, extremely low visibility, or rising water levels to indicate it's time to leave your vehicle.
Signs of Rising Water Levels
When stranded in a snowstorm, be aware of your surroundings, especially if you’re near a body of water like a lake or river. Rising water levels can be a sign that you need to evacuate your vehicle immediately. If you notice water levels rising at a rate of 1 inch per hour or faster, it’s time to leave. This can happen quickly, especially if you’re near a frozen lake or river that’s starting to thaw.
Extreme Cold and Poor Visibility
Intense snowfall and extremely low visibility can also indicate it’s time to leave your vehicle. If you can’t see more than 10-15 feet in front of you, it’s difficult to navigate safely. In extreme cold temperatures (below -20°F / -29°C), even brief exposure outside can be life-threatening. If you’re experiencing these conditions, it’s best to seek shelter and warmth as soon as possible.
Other Indicators to Leave Your Vehicle
Other signs that it’s time to leave your vehicle include strong winds, falling branches, or other environmental hazards. If you’re near a forest or wooded area and notice branches breaking off at a rate of 10-20 per hour, it’s a sign that the storm is intensifying and you should seek shelter. Additionally, if you notice that your vehicle is surrounded by deep snow or your exhaust pipe is buried, it’s a sign that you need to leave your vehicle to avoid carbon monoxide poisoning.
