Despite threats of 4-5 inches of rain along the I-85 corridor due to the remnants of Hurricane Ida, it appears that most of the Atlanta area only received in the neighborhood of 2-3 inches of precipitation. Here in Lawrenceville, I’ve recorded 1.87 inches since the rain started early this morning. In Alpharetta, they recorded 3.11 inches, and in Johns Creek, the Atlanta Athletic Club measured 2.98 inches.
Other Georgia locations received much more rain. Pine Mountain was reporting 5.48 inches of rainfall today, while Columbus recorded 5.01 inches. These two areas seem to be the hardest hit, and from glancing at the radar this afternoon, it seems that Alabama got the most rain. Gainesville recorded 2.44 inches, while Marietta saw 2.77 inches. The official Atlanta rain gauge at Hartsfield Airport recorded 2.71 inches.
The rain did cause some area rivers to reach flood stage. Big Creek in Alpharetta is flooding, as is Pew Creek in Gwinnett County, Peachtree Creek in Atlanta, and the Nickajack Creek in Cobb county. Suwanee Creek is expected to experience minor flooding tomorrow morning.
There’s still more rain to come before Ida bids Georgia farewell (and her remnants cause problems in the Delmarva peninsula). But, looking at the radar now, it seems like the forecasters should have picked I-59 in Alabama as the worst hit area, rather then the I-85 corridor.
