Climate Fact: National Annual Precipitation Trends (Georgia)
Most areas of the United States are now receiving more total annual rainfall than they did 50 years ago. There is significant regional variability in this trend, however. Adding up the total regional positive and negative trends, the U.S. as a whole is now receiving five percent more precipitation each year. The Northeast and northern Midwest have shown the greatest increases in average annual rainfall, with the Southeast and Southwest exhibiting the greatest rainfall reduction trends. Some of the Nation’s most pronounced rainfall reduction trends have occurred in Georgia, where there has been a statewide five to 15 percent decrease in total annual rainfall.
