Do not take a bath or shower. Unplug appliances not necessary for obtaining weather information. Use the phones only in an emergency. Telephone lines and metal pipes can conduct electricity. Turn off air conditioners.
Power surges from lightning can overload compressors.
Get to higher ground if flash flooding or flooding is possible. Once flooding begins, abandon cars and climb to higher ground. If you are golfing or farming, find shelter immediately. Find a low spot away from trees, poles and fences. Make sure the place you pick is not subject to flooding.
