Keep car windows closed. Telephone lines and metal pipes can conduct electricity. Unplug appliances and avoid using them or the telephone. Avoid taking a bath or shower, or running water for any other purpose. Turn off the air conditioner.
Power surges from lightning can overload the compressor, resulting in a costly repair job.
Draw blinds and shades over windows. If windows break due to objects blown by the wind, the shades will prevent glass from shattering into your home. If you are in the woods, take shelter under the shorter trees. If you are boating or swimming, get to land and find shelter immediately. Go to a low-lying, open place away from trees, poles or metal objects.
