More rain is predicted for areas already coping with flooding after a storm dumped 2 to 3 inches of rain across an area stretching north and west of Sturgis towards Sundance.

Up to 4 inches of rain was reported west of Sundance, Wyo., according to National Weather Service meteorologist Susan Sanders.

Some areas in an area from Pine Ridge, north to Faith and back towards Buffalo have received 1 to 2 inches of rain.

Rain will continue falling throughout the day in the northern Black Hills and northwestern corner of the state, Sanders said.

A bigger system move north out of Nebraska and swirl back towards Hills area later today bringing up to 1-2 inches of rain. Locally, higher amounts are possible, Sanders said.

A few heavy thunderstorms are possible, but any severe weather with high winds and hail is expected to stay well east of the region, Sanders said.

Flooding will remain a serious threat for several days.

"Once all this water stops falling there's still going to be flooded creeks and streams," Sanders said. "Eventually, it's all going to flow into the rivers, there's an extreme amount of runoff."
