Don't seek shelter or a telephone unless you see one close by. For heat, turn on the car engine for brief periods. To keep water pipes from freezing, wrap them in pipe insulation. During long cold periods, allow each faucet to drip. This will help to prevent the pipes from freezing.
Cold weather puts a strain on the heart, even without exertion.
Be careful when shoveling snow or pushing a car. You may also want to contact your National Weather Service Meteorologists for local snowfall statistics.
