During lake effect snow, the weather can vary from bands of locally heavy snow with greatly reduced visibilities to dry conditions just a few miles away. Be prepared for rapid changes in weather, visibility, and road conditions. Consider delaying travel. If you must travel, drive with extreme caution. Leave plenty of room between you and the motorist ahead of you, and allow extra time to reach your destination. Avoid sudden braking or acceleration, and be especially cautious on hills or when making turns.
