Northeast Oklahoma
River/Basin Flooding
August 19, 1997

Event Summary 

Three-inch rainfall totals were common across Northeast Oklahoma in the days preceding August 19. An upper-level storm system was forecast to move across the area, bringing more rain to already-saturated ground. Forecasters advised people to remain aware of the potential for flash flooding. Although the heavy rainfall did not materialize and only minor flooding was reported, the case serves to highlight the use of forecast guidance in being prepared for flooding.
