The rain was welcome today for those fighting fires in Custer County.
Fire crews continue to make progress on the Rankin Fire, located in the northern part of Wind Cave National Park.
The fire is 90 percent contained and while there was no new growth of the fire yesterday the acreage did increase to 2,133 acres due to better mapping.
Today crews are continuing to improve containment lines and are mopping up the few remaining hot spots.
Fire behavior is expected to be minimal due to the cooler temperatures and rain.
Officers are asking travelers along US Highway 385 and State Route 87 through the park to use caution as fire traffic will continue to be heavy along this corridor at times.
