ri-state region that due to unusually high temperatures, the demand for electricity may exceed the supply. Air conditioners and fans are in constant use during this hot summer weather, putting an enormous strain on electricity supply. This increase in demand for electricity may result in power failures in scattered areas throughout the region. In order to help avoid blackouts, citizens are asked to keep their air conditioners set at temperatures no lower than 80 degrees Fahrenheit and to run them only intermittently during the hottest part of the day. In addition, any non essential use of electrical appliances should be avoided during the middle of the day. If a power failure occurring in your neighborhood should cause a potentially life-threatening emergency, call the electricity company's emergency hotline at 555-9745. Emergency workers are standing by in your area ready to respond where needed.
