Monsoonal moisture streaming into the area, combined with slow moving thunderstorms, produced a narrow area of heavy rain from Black Hawk to Rapid Valley. Runoff from this rainfall caused minor street flooding on a few city streets in Rapid City, flooded open agricultural fields in Rapid Valley, and caused high flows and minor flooding along Rapid Creek.
