NWS: Above normal chances for Big Sioux River flooding in Codington, Hamlin counties
February 24, 2023
ABERDEEN, S.D. (KWAT)–Lost in all the talk about this week’s snowstorm is a new flood forecast released by the National Weather Service Thursday.
They say even though there is snow pack across most of the area, due to ongoing drought conditions, the chances for minor, moderate, or major flooding across much of the region are generally below normal.
The exception is on the James River near Ashton where the chances are above normal for minor flooding, and across the Big Sioux basin in Codington and Hamlin counties where the
chances are above normal for minor to moderate flooding.
The flood threat through this spring, both in location and severity, will largely be determined by future rain or snowfall.
The next update from the National Weather Service will be released on Thursday, March 9.
