Do NOT run your snow-buried car's engine
Sure, you're cold. And tired. Shoveling is exhausting. But don't take your break in the car with the engine running. It could put you in a cold grave. Consider this message from a WeatherBlog reader in Columbia:
"Frank, you may want to help people not kill themselves as I almost did.
"I managed to dig a trench to my car (Columbia, so 30+ inches) and had the great idea to defrost it. My satellite radio, unlike my satellite TV, was working so I sat in it while it was running.
"I started seeing that distortion effect INSIDE THE CAR and realized carbon monoxide was coming in the car.
"Someone, I guarantee, will sit in their car cave while it defrosts and accidentally asphyxiate."
Remember, the snow piled around your car can trap carbon monoxide coming from the exhaust. It can quickly incapacitate you before you realize what's happening. Then it will kill you. Clear snow from the exhaust pipe and leave the engine off until the car is ready to roll.
