USGS Defines September Floods As Epic
Nov 5th, 2009 | By Editor | Category: All Posts, Community, FYI, Neighborhood, Stone MountainThe U.S. Geological Survey has stated that the flooding experienced in north Georgia was “extremely rare, epic, stunning and off the charts”. Statistically it was the type of flood that is only projected to be experienced once every 500 years.
Average annual rainfall for metro Atlanta is around 50 inches. Many locations received rainfall totals approaching the 20 inch mark during the 24 hour period of September 20th through September 21st. That equates to 40% of an average annual rainfall in one day.
Scientists are describing the September flooding as one of the worst flood events experienced in the U.S. in the last 100 years.
