Assuming the flow is correct, Haw at Bynum is pushing 50,000 cubic feet a second, that’s about half what the Guadeloupe was at peak near Kerrville on the morning of 7/4.

If this had been snow, I would have been mad to miss out just to the east. But my 3" is perfect compared to the 10"+ just to my west. I do worry about the water rise to Falls Lake. I bet they're releasing the max amount of water at the dam right now. Might run over there later this morning.
 
Drove home from the Triad (and the mountains earlier in the day) last night. Got back at midnight and it was probably the scariest drive of my life. 40 was completely flooded at one spot, so we got off and tried a side road which had trees down and another completely flooded spot, so we had to turn around along with a ton of other cars. Eventually found 40 again and we must’ve gotten around the currently flooded area, so we were able to take it the rest of the way from there. Insane stuff. I guess driving last night was a bad idea, but it was a busy weekend and I wasn’t paying super close attention to how bad the storm had gotten. 🤦‍♂️

I can see how dangerous flooding can be at night. It’s hard to see the areas of standing water in the dark.

City of Mebane is experiencing water problems due to heavy rainfall.

Here’s a message from City of Mebane:

“Efforts to operate the Mebane water system at a low pressure level will be unable to be maintained as the impacts of Tropical Storm Chantal have impacted Orange-Alamance Water Authority's ability to provide water to the City of Mebane. As a result, the City of Mebane is asking all customers to limit their water usage to zero level for the remainder of today, effective upon this call. An update will be provided at 5 p.m. or beforehand if Orange-Alamance Water Authority can provide additional water or the Graham-Mebane Water Treatment Plant operations can be restored.”
