IF this (near 0.50" ZR) were to be close to verifying, I want to check one other event to make sure but I do believe this would be the worst widespread ZR for upper coastal counties of GA to far S SC since Jan of 1922. It almost certainly would be worst for right in the city of SAV since then and by what I think would be some margin. So, a truly historic (96 years) hit is a real possibility there. It is crucial that ZR amounts don't rise above here because that's when the damage and outages would rapidly increase. The JMA and ICON qpf's would cause massive damage. Hopefully they're both overdoing their 1.25" (which would be near the severe hit of 1922) as often is the case with the JMA. As it is at this near 1/2" level, it would already cause quite a number of problems for sure, including many outages and slippery driving/walking in certain areas, especially if it gets down to 30. We've got numerous very large oaks in and near the city that would be a big concern with just the 0.50" of ZR.
The comparison to the surface wx maps of the massive Jan 1922 ZR is eerily similar.
Keeping in mind the Irma hit, there have been other instances of a big tropical hit in the area followed by a sig wintry hit somewhere within the CHS-SAV corridor the following winter: 1894/1895, 1898/1899, 1989, 1979/1980 come to mind.
