What should I do to remain safe inside?

• Keep away from windows and doors.  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.)
  
• Don't use the telephone unless there's an emergency (telephone lines an conduct electricity.)  Cordless or portable phones are safe.
  
• Avoid taking a bath or shower, or running water for any other purpose (lightning can pass through metal pipes.)  Stay away from water faucets, sinks, and tubs.
  
• Unplug and don't use electric appliances(it is safe to leave the lights on.) Stay away from the TV.  Turn off the air conditioner (a power surge from lightning can overload the compressor, resulting in a costly repair job!)
