National Weather Service Sioux Falls, SD
The National Weather Service in Sioux Falls has issued a flood watch for Davison, Hanson, McCook, Moody, Lake, Miner and Brookings counties in South Dakota.
The flood watch remains in effect from Wednesday morning through Thursday evening.
A large storm system will bring warmer air northward, along with the potential for moderate to locally heavy rainfall Wednesday and Wednesday night. This combination of conditions will result in an increased risk of river flooding, as well as aerial flooding due to the combination of heavy rain, snowmelt, and poor drainage due to frozen soils.
