* Urban and Small Stream Flood Advisory for...
  Lebanon County in south central Pennsylvania...

* Until 1030 PM EDT

  occurred over the past 2 hours across parts of Central and
  Southern Lebanon County, mainly to the east and northeast of
  Lebanon. Additional rainfall of 1 to 1.5 inches is expected across

  Gretna Heights, Timber Hills, Lawn and Avon.


PRECAUTIONARY/PREPAREDNESS ACTIONS...
