The episode as NWS RNK wrote it up.
A stationary front draped east to west across northern North Carolina provided the focus for training showers and thunderstorms during the evening of the 17th. Winds were from the east along the North Carolina & Virginia state border around high pressure centered over New England. The easterly windflow carried moist Atlantic air across Stokes and Rockingham Counties, with precipitable water values ranging from 1.5 to 1.7 inches during the evening. Several rounds of showers and storms passed across the area, with rainfall rates times exceeding four inches per hour per rain gage data and MRMS (Multi-Radar/Multi-Sensor System) estimates. This caused flash flooding of several local waterways, with at least two roads washed out in Stokes County, as well as a water rescue of stranded motorists.
The Roanoke radar (KFCX), 72 km away, was scanning. The volume nearest the first event began at 03:57 UTC.
5 flood, 4 flash flood, 2 heavy rain. Local standard time, as filed.
A personal weather station (Weather Underground: KNCWALNU50) recorded a 24-hour rainfall amount, ending at 11 pm EST on the 17th, of 6.67 inches. This 24-hour total is between a 25-year and a 50-year Average Recurrence Interval event per NOAA Atlas 14 Point Precipitation Frequency estimates.
A personal weather station (Weather Underground: KNCWALNU10) recorded a 24-hour rainfall amount, ending at 11 pm EST on the 17th, of 6.41 inches. This 24-hour total is about a 25-year Average Recurrence Interval event per NOAA Atlas 14 Point Precipitation Frequency estimates.
Numerous roads were flooded and impassible across Rockingham County, with several of the reports concentrated to the north and east of Reidsville. This included a report of flooding along W. Harrison Street in Reidsville, where one car stalled in the high water near the intersection of W. Harrison Street and Market Street. An underpass between E. Harrison Street and W. Harrison Street was also reported flooded and impassible until the water receded. North of Reidsville, Wolf Island Creek was observed overflowing its banks across Wolf Island Road, where two people required rescue when their vehicle was washed off the road into a corn field next to the creek. No injuries were reported. No roads were reported damaged by the flooding, which were open to traffic when the flooding receded. Damage estimates are for the vehicles.
Reed Creek rose several feet out of its banks across Bethesda Church Road. The culvert underneath the road was completely washed out several feet downstream, causing the road to collapse and be impassible to traffic until repairs are complete. Debris lines indicate that the creek was over 80 feet wide (normally around 25 feet) at the height of the flooding event. Because of the dark, one car drove into the flood waters and became stranded, with one occupant needing rescue. No injuries were reported. MRMS data indicated 6-hour rainfall amounts ending 9 pm EDT were 1.5 to 1.6 times that of 6-hour flash flood guidance, while the average recurrence interval for 6-hours was a 25 year event.
Little Beaver Island Creek overflowed at least 25 feet out of its banks, and completely washed out a 30 foot wide section of Franklin Moore Road, leaving a large gap where the road used to be located. The road is completely impassible until repairs can be completed. No injuries were reported in this event. MRMS data indicated 6-hour rainfall amounts ending 9 pm EST were around 1.5 times that of 6-hour flash flood guidance, while the average recurrence interval for 6-hours was about a 25 year event.
Moore Springs Road was washed out by Cascade Creek, making the road impassible until repairs can be completed. No injuries were reported. MRMS data indicated 6-hour rainfall amounts ending 9 pm EST were 1.5 to 1.6 times that of 6-hour flash flood guidance, while the average recurrence interval for 6-hours was a 25 year event.
Dan River Shores Road was observed flooded by the Dan River due to runoff from heavy rain. No damage was reported.
The Dan River was observed flowing out of its banks across portions of Moratock Park near the community of Danbury. No damage was reported to the park.
Madison River Park was observed flooded several feet deep as the Dan River at Madison rose out of its banks. It is unclear if releases from releases from Belews Lake several miles upstream from the park played a role in the flooding as there is no stream gage along the Dan River between Pine Hall and Wentworth. Damage estimates are related to cleanup of the park after the flooding receded.
The Dan River at Wentworth, NC (WENN7) crested at 19.96 feet (19,400 cfs) at 7:15 AM EDT on Sept. 18th (18/1115 UTC) due to runoff from heavy rain falling the evening prior. This is the highest crest on the river since January 2024. This crest rates between a 2-year and a 5-year Average Recurrence Interval (ARI), or between a 50% and a 20% Annual Exceedance Probability per USGS StreamStats. The flooding was the result of between 5 and locally 8 inches of rain that fell across portions of Stokes and Rockingham Counties upstream from the gage on the 17th.
The Dan River at Pine Hall, NC (PNHN7) crested at 23.44 feet (16,200 cfs) at 8:00 AM EDT on Sept. 18th (18/1200 UTC) due to runoff from heavy rain falling the evening prior. This is the highest crest on the river since January 2024, when the river crested at 24.60 feet. This crest rates between a 2-year and a 5-year Average Recurrence Interval (ARI), or between a 50% and a 20% Annual Exceedance Probability per USGS StreamStats. The flooding was the result of between 5 and locally 8 inches of rain that fell across portions of Stokes County upstream from the gage on the 17th. The river caused portions of Joe Ayers Road along the right bank just upstream of the gage to be flooded 1-2 feet deep near Pine Hall Road, making the road impassible. Nearby River View Golf Course was observed completely flooded when the river rose out of its banks. Several farm fields along River Road were flooded as well. Damage estimates are related to cleanup from the flooding.
