At the risk of doxing myself, I can give my input from a smaller town south of Asheville. First off, it was basically pouring down rain starting on the 24th, though it was still sprinkling a bit beforehand. At some point on Friday, cell service and internet went down for the entire town, though luckily most of the town still had power (and those that didn't ended up getting it back within a day or two). There were a few hot spots within the city where people could get cell service, but only certain carriers. A lot of businesses here stayed open and just went cash only, since we were lucky enough to still have power. The water supply was unaffected, thankfully. There was little to no flooding here from what I've heard, though the highway up to Asheville was flooded so travel up there was anywhere from impossible to dangerous to fine depending on who you asked and when.
I took a trip east to Charlotte yesterday because I had business there, but also took it as an opportunity to pick up supplies that may be a bit more annoying to get in town. Honestly the roads out weren't that bad. A lot of downed trees that were pushed to the side of the road, some precariously hanging over the street, but there was really only one spot that had a very minor detour around some downed trees. At least in the area south of Asheville, Hendersonville seems to have been hit the worst. Save for buildings with back up generators like the hospital, the whole town is without power, not even street lights are working. It was pretty eerie driving through there in the middle of the night and not seeing any signs of life at all. I did see some military on their way in while I was on my out though, so they're likely getting some aid.
I was honestly expecting it to be days or even weeks before we got cell or internet back in town, but I was surprised to find that it was restored while I was out yesterday. I hope Asheville is able to recover soon, I like to take day trips up there on the weekends sometimes, but it seems like it'll be a while before I can do that again.
ETA: I also forgot to mention that a number of the road closures that I was seeing in the early days were just completely wrong. I saw a map that marked the highway running through my town as being entirely closed but that was incorrect, there wasn't even a tree in the road. It could have just been an assumption based on the lack of ability to communicate with the area, but take road closures with a grain of salt. They could be wrong entirely, or they could be cleared up already with water draining and trees getting cleaned up.
