The episode as NWS RNK wrote it up.
The remnants of Hurricane Debbie moved north toward the area on August 8th, 2024. A strong southeast flow of wind on the system's northern extent, along with wet soils due to heavy rainfall, helped to cause downed trees and power lines over portions of North Carolina. Winds gusted to at least 30 to 35 mph in parts of the area with stronger gusts suspected close to 45 mph. The strong winds continued into the morning hours of August 9th, 2024. In addition to the strong winds, two funnel clouds were observed in Rockingham County. The highest rainfall totals were observed in Yadkin, Surry and Stokes Counties, where three to five inches were recorded, amounts that were generally 10-year to locally near 25-year average recurrence interval (ARI) events per NOAA Atlas 14 Point Precipitation Frequency estimates. Rainfall amounts for most of the remainder of northwest North Carolina were under three inches and generally less than 10-year ARI events. There were long breaks in between rainfall bands, some lasting two to three hours, which helped diminish the flooding threat. Another factor that decreased the flash flooding potential were antecedent soil conditions and streamflows that were near normal, but still recovering from drought conditions occurring earlier in the summer. As a result, bands of heavy rain did cause several first and second order streams to flood rapidly out of their banks, making nearby roads impassible for several hours until the water receded. The Dan River at Wentworth barely exceeded flood stage by less than a tenth of a foot for a little over three hours before quickly receding.

Area Forecast Discussion
National Weather Service Blacksburg VA
634 AM EDT Thu Aug 8 2024
.SYNOPSIS...
Moderate to heavy rainfall from current Tropical Storm Debby will
increase in coverage over the area Thursday into Friday, and will
increase the risk of flooding, especially along and east of the Blue
Ridge. Debby pushes to the northeast by Friday night, cooler
and drier air arrives by Saturday, and will bring more tranquil
weather for the start of the week.
&&
.NEAR TERM /THROUGH FRIDAY/...
As of 300 AM EDT Thursday...
Key Messages:
1) High Risk of flooding today and tonight. Heavy rainfall will
likely result in flash flooding and river flooding.
2) Rotating storms could produce tornadoes across the Virginia and
North Carolina Piedmont.
Tropical Storm Debby is currently located along on the South
Carolina coast, recently making landfall. Rain continues to develop
and increase in coverage and intensity across the Carolinas this
morning. Strong easterly flow ahead of Debby has resulted in areas
of upslope rain along and east of the Blue Ridge. These will
continue through the morning and increase in coverage as 850mb
moisture transport continues to strengthen. Main swath of rain
directly associated with Debby is beginning to push into Southside
Virginia and north central North Carolina. This will continue
through the morning and reach the 81 corridor by noon.
The threat for very efficient rainfall rates continues to increase
across our area. Fueled by high Precipitable Water and terrain
enhancement, high rainfall rates will likely result in flash
flooding over the Blue Ridge, Foothills, and Piedmont areas of
Virginia and North Carolina. Some convectively enhanced bands will
also occur across central Virginia, leading to the increased threat
of flash flooding. The aforementioned areas are where the confidence
of the heaviest rainfall remains. Heaviest rain timing appears to be
from 2pm this afternoon through 2am Friday.
Secondary concern is the threat for rotating storms this afternoon
and tonight. Low pressure center will track somewhere along the 81
corridor through Virginia and the area of concern for tornadoes will
be in Central Virginia, particularly along and east of US29. Modeled
0-3km helicity values nearing 300 m2/s2 coinciding with CAPE nearing
1000 J/kg should support convective rainbands with embedded
supercells capable of producing tornadoes. To support this, several
radar confirmed tornadoes have already occurred this morning
across eastern North Carolina.
Be weather aware over the next 24 to 36 hours as conditions could
rapidly deteriorate. Have a way to receive warnings if a flash flood
warning or tornado warning is issued.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 300 AM EDT Thursday...
Key Messages:
1. Lingering light showers possible through Friday night.
2. Mostly dry weather expected for the remainder of the weekend.
The remnants of what is currently Tropical Storm Debby will be into
the upper Mid Atlantic and New England by Friday night, as the
system gets lifted northward by an upper trough. Some lingering
showers in the area are possible overnight and into early Saturday
morning, as a surface front pushes into the region from the west.
Behind the front and tropical system, a cooler and drier airmass
will build into the area, and high pressure will become situated
overhead through Sunday. For the remainder of the weekend, weather
will be much drier, and only very limited chances of precipitation,
mainly in NC and southward, as the front stalls across the
southeastern states.
Temperatures will be cooler, near to a couple degrees below seasonal
normals, in the mid to upper 70s in the west, and mid 80s in the
east. Plentiful sunshine and lower dewpoints are expected through
Sunday.
&&
.LONG TERM /MONDAY THROUGH WEDNESDAY/...
As of 300 AM EDT Thursday...
Key Messages:
1. Quieter weather pattern for beginning of the week, with limited
precipitation probabilities.
2. Temperatures near normal through the period.
A much quieter weather pattern is expected for the beginning of the
work week, with surface high pressure settled over the Ohio Valley
and Mid Atlantic region, keeping precipitation chances limited. Some
isolated to scattered showers and thunderstorms are possible
Tuesday afternoon, mainly along and south of the VA/NC border, as a
front drifts northward into the Carolinas, but probabilities are low
at this time.
Temperatures will be near normal through the period, in mostly the
70s west of the Blue Ridge, and low to mid 80s east.
&&
.AVIATION /12Z THURSDAY THROUGH MONDAY/...
As of 300 AM EDT Wednesday...
Flight conditions continue to deteriorate this morning, with
most locations already sub-VFR. Expect conditions to continue to
worsen through the day as more widespread rainfall enters the
area. Rain intensity will increase through the day and expect
IFR/LIFR through tonight for all terminals.
Worst conditions appear to be from about 2pm this afternoon
through 2am Friday.
Winds also increase today as well, gusty at times into the 25kt
range.
AVIATION OUTLOOK...
Remnants of Debby continue moving N through the region through
Friday morning. Improving flight categories expected as Debby
moves away from the region Friday night. High pressure moves
into the region this weekend and VFR is expected outside of
areas of morning fog through early next week.
&&
.HYDROLOGY...
As of 315 AM EDT Thursday...
A rare High Risk for excessive rainfall has been issued for a
large portion on the area extending from the Blue Ridge of
Virginia and east into the Virginia and North Carolina Piedmont.
The last issued high risk for our area occurred in May of 2020
where significant flooding occurred with that event.
Expecting heavy rainfall to increase across the area today from
east to west as Debby continues to push inland across the
Carolinas, and then eventually north along the Blue Ridge
tonight. Very high ambient moisture associated with the tropical
remnants will allow very high efficient rainfall rates. Overall
much of the area remains in a drought, so should be able to
handle lower rainfall rates to an extent. However, the concern
is with convectively enhanced rainfall bands training
repeatedly across the mountains and Piedmont, coupled with PWAT
values exceeding 2.25 inches. This will produce large amounts of
rain within a short period of time, thus resulting in the high
risk of excessive rainfall.
Main stem river flooding is also expected in the Dan and
Roanoke River basins. Areawide 4 to 8 inches is expected and
likely to see several locations along the Roanoke and lower Dan
to go into flood stage by Friday.

Numerous trees were blown down across the county, with several of these trees falling on power lines. Damage values are estimated.
Multiple roads were flooded and impassible across Yadkin County due to bands of heavy rain passing across the county. This includes the intersection of Center Road and Bryant Road, where a vehicle became stranded in the flood waters. Rainfall rates were sustained at 1 to 1.5 inches per hour, with around two inches of rain falling across portions of the county within a three hour period.
Numerous trees were were blown down across the county. Damage values are estimated.
Winds blew numerous trees down throughout the county. Fallen trees also brought down power lines around three miles west of Huntsville. Damage values are estimated.
Multiple roads have become flooded and impassible due to persistent rounds of heavy rain across the county, falling at rates of 0.5 to 1 inch per hour.
Numerous roads were reported flooded and impassible across Rockingham County, including River Road and Wilson Road, as well as others within the communities of Eden and Reidsville. Flooding occurred at different times through the day for different locations depending on when the heavier rain bands passed across those areas.
Kerrs Chapel Road was flooded and impassible by Stoney Creek which overflowed its banks several inches deep across the road. No damage was reported to the road, and it was open to traffic after the water receded.
Numerous trees were blown down throughout the county due to a combination of strong winds and wet ground. One tree fell onto a mobile home three miles south-southwest of Reidsville, directly causing one fatality. Damage values are estimated.
A funnel cloud was reported above Grooms Road.
At a location one mile north of Bethel, strong winds blew hay bales across a road, destroyed and blew away a trampoline and a wooden children's playset. Damage values are estimated.
The Dan River at Wentworth (WENN7) crested at 19.09 feet (16,500 cfs) at 4:45 AM EST, just above the minor flood stage of 19.0 feet. This flood was about a 50-percent annual exceedance probability event (2-year ARI) per USGS StreamStats. The flooding impacted mainly low spots along the river with minimal impact noted.
