Blue Ridge, GA – An extraordinary rainfall event has struck the mountains of northern Georgia, where more than 11 inches of rain was recorded near Blue Ridge, exceeding a 1 in 1,000 year rainfall threshold and marking one of the most extreme precipitation events documented in the region.
According to the National Weather Service in Peachtree City, rainfall measurements from Wednesday night into Thursday, November 5, confirmed 11.19 inches near Blue Ridge in Fannin County.
The National Weather Service determined that both the six hour and 12 hour rainfall totals exceeded the 1 in 1,000 year precipitation thresholds established by NOAA Atlas 14.
During one six hour period, from 8:45 p.m. to 2:45 a.m., an astonishing 10.28 inches of rain fell at the reporting location.
The 12 hour total reached 11.19 inches, exceeding the highest rainfall recurrence interval that the available NOAA data can reliably estimate.
Other communities across the mountainous region also reported exceptionally heavy rainfall.
Higdon recorded 9.08 inches, while locations near Mineral Bluff reported 8.40 and 7.57 inches.
Additional measurements included 6.38 inches near Colwell and 6.24 inches west of Nottely Dam.
The extreme rainfall was concentrated around Blue Ridge, Mineral Bluff and surrounding communities in Fannin County, with substantially lower totals reported in some nearby locations.
Such intense rainfall can rapidly overwhelm drainage systems, swell streams and create dangerous runoff conditions, particularly across mountainous terrain.
However, the National Weather Service emphasized an important distinction between rainfall rarity and flooding severity.
A 1 in 1,000 year rainfall event does not automatically mean a 1 in 1,000 year flood occurred.
The U.S. Geological Survey will need to conduct additional surveys to determine the actual flooding recurrence intervals.
The designation also does not mean such rainfall can occur only once every 1,000 years. It represents an estimated 0.1% annual probability of exceeding that rainfall threshold at a particular location.
Residents across northern Georgia should continue monitoring local emergency information and National Weather Service updates as officials assess the storm's impacts.
