2003 Severe Weather Summary for North and Central Georgia

The year 2003 was noted by a marked increase in the amount of severe weather - particularly flash flooding - across north and central Georgia. The amount of flash flooding occurring during the year was quite remarkable, with 184 flash flood events and an estimated damage of $31.37 million. Flash flooding of this magnitude has not been observed in north and central Georgia in many years. With respect to severe weather, May 2nd and May 5th through May 8th stands out as the years most active weather period. These dates marked an extensive period of severe thunderstorms, tornadoes, and flash flooding. There were 124 thunderstorm wind, 95 hail, 51 flash flood, 22 lightning, and 5 heavy rain events occurring during these five days!

Significant severe weather events occurred on February 22nd, March 5 - 6th, March 19 - 20th, April 25th, April 30th-May 2nd, May 5 - May 8th, May 17 - 22nd, June 16 - 17th, June 30th - July 1st, July 10th, July 13th, July 22nd, and August 16th. After mid-August, much quieter weather conditions prevailed for the remainder of the year, with only a few events occurring on approximately a half-dozen days after September 1st. Despite the very wet and stormy conditions during the first half of the year, there was a notable absence of tropical storms. Tropical storm Bill, which moved across north Georgia on July 1st, was the only named storm to affect north and central Georgia during the year. The tropical storm simply aggravated the saturated ground conditions resulting in more flooding.
