Telephone lines and metal pipes can conduct electricity. Unplug appliances not necessary for obtaining weather information. Avoid using electrical appliances. Use phones only in an emergency. Turn off air conditioners.
Power surges from lightning can overload the compressors.
Do not take a bath or shower. Water is an electrical conductor. If lightning is occurring and a shelter is not available, get inside a hard-top vehicle and keep the windows up. If no vehicle is available, find a low spot away from trees, fences and poles. Be alert to the possibility of flash flooding.
