Up to 6.5 inches of rain drench Richland CountyHANKINSON, N.D. – As much as 6.5 inches of rain drenched parts of Richland County Monday morning when a thunderstorm passed through.
The deluge sparked a flash flood warning until Monday evening as runoff from the rainfall as the county dried out.
Residents reported to the National Weather Service that several inches of rain dumped across the area between 9:40 a.m. and 11 a.m.
A resident measured 6.5 inches of rain in Hankinson at around 11 a.m., while a trained weather spotter reported 3.2 inches of rain 10 miles northeast in Mantador around the same time.
The mass amount of rain in only a short amount of time filled roadside ditches.
Some roads – such as County Road 3 – were also temporarily under water after the storm, the weather service said.
The cities of Hankinson, Lidgerwood, Wyndmere, Barney, Great Bend, Mantador and Mooreton were affected by the flash flood.
The rain moved on to drench parts of northeast South Dakota, including Aberdeen.
The weather service said the heaviest rainfall fell from Stiles and Hankinson to the South Dakota border.
