Where was the heaviest rain in Deep South?

Heavy and persistent rains have swamped many sections of the Deep South in recent weeks.  It has erased longstanding drought in many spots, but replaced it with terrible flooding that has caused numerous deaths - at least seven in Georgia alone - and much property damage.

NASA's Earth Observatory has computed cumulative rain totals based on satellite observations and generated a map of the region showing where the heaviest rain was concentrated.

The lightest amounts are in pale green, the heaviest (more than 300 mm, or about 12 inches) in dark blue. Here's more.

Frank,
Great Blog posts this afternoon! The graphic concerning the rainfall in the south seems to indicate the largest concentration of rain in Georgia is right over Lake Lanier. If I remember this is where the drought was concentrated over the last several years. It is also the primary water source for Metro Atlanta. Do you know if the lake has returned to normal water levels? Is this a drought busting rainfall or merely an reprieve in a longer standing cycle?

FR: There were some remaining dry conditions in northeast Georgia as of Sept. 15, but I suspect those are gone now, too. Lake Lanier is now predicted to be at "full pool" by early 2010, if not sooner.
