The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Greensboro/Hi Pt, NC (KGSO), launched 12:00Z, 7.2 hours before the alert went out and 264 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE WILMINGTON NC
309 PM EDT SUN AUG 29 2004
THE NATIONAL WEATHER SERVICE IN WILMINGTON NC HAS ISSUED A
* FLASH FLOOD WARNING FOR...
WILLIAMSBURG COUNTY IN NORTHEAST SOUTH CAROLINA
* UNTIL 615 PM EDT
* AT 310 PM...THE CENTER OF TROPICAL STORM GASTON WAS OVER
WILLIAMSBURG COUNTY. GASTON WILL CONTINUE MOVING SLOWLY
NORTHWARD THROUGH WILLIAMSBURG COUNTY OVER THE NEXT TWO TO THREE
HOURS. DOPPLER RADAR ESTIMATES RAINFALL RATES NEAR THE CENTER OF
THREE TO FOUR INCHES PER HOUR. THIS IS SUFFICIENT TO PRODUCE
RAPIDLY RISING WATER IN THE WARNED AREA. THE HEAVIEST RAINFALL IS
EXPECTED ALONG AND WEST OF A LINE FROM LANE TO KINGSTREE TO
CADES.
DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. VEHICLES CAUGHT IN RISING WATER SHOULD BE ABANDONED QUICKLY.
MOVE TO HIGHER GROUND.
PEOPLE LIVING ALONG AREA CREEKS AND STREAMS SHOULD BE ON THE LOOKOUT
FOR RAPIDLY RISING WATER. MOVE TO HIGHER GROUND IF FLOODING IS
OBSERVED AND REPORT THE FLOODING TO THE NEAREST LAW ENFORCEMENT
AGENCY. ASK THEM TO RELAY YOUR REPORT TO THE NATIONAL WEATHER
SERVICE FORECAST OFFICE IN WILMINGTON NC.
