The Dan River at South Boston is expected to crest near 27.4 feet this morning, well above the 19 ft. flood stage here, according to the National Weather Service.
Runoff from heavy rain Sunday night into Monday morning will continue to cause flooding along the lower Roanoke and Dan Rivers, NWS officials said yesterday.
Along the Dan River at Danville, the river was cresting and was expected to begin falling before noon Tuesday. Rises were expected to continue downstream at Paces into Tuesday evening and early Wednesday morning at South Boston, where moderate flooding is expected.
The river’s crest in South Boston compares to a previous crest of 27.4 feet on April 13, 2003, according to the NWS.
The flood warning continues for the Dan River near Paces until Thursday afternoon. At 9 a.m. Tuesday, the stage was 22.9 ft. and rising with minor flooding occurring and moderate flooding forecast. Flood stage is 20 ft.
The river was expected to continue rising to near 24.1 ft. by Tuesday evening and will fall below flood stage early Thursday morning.
On Tuesday, Riverdale Auto was moving vehicles to higher ground. “It takes a while to move this many,” said businesswoman Bunny Propst, who estimated the auto company would move approximately 80 vehicles.
Already Monday afternoon, the South Boston river gauge was exhibiting the same “stuck” behavior it did last year, according to the NWS hydrologist.
“This gauge is problematic,” agreed hydrologist Peter Corrigan. However, Corrigan emphasized the NWS is not blind forecasting, monitoring both Danville and Paces, which customarily reach crest stage 24 hours to 12 hours, respectively, before South Boston.
Also, Corrigan said prior to the heavy rain that is generating minor to moderate flooding along the Dan River, a meeting had been set Thursday to address the river gauge problem in South Boston. The meeting, to be held in Halifax, is expected to include the NWS, area emergency service representatives and the United States Geological Survey (USGS).
“The USGS operates most real time river gauges in the state,” explained Corrigan. “We (NWS) do not maintain equipment on the river,” he added.
