The remnants of Tropical Storm Fred were forecast to move across the region. Out ahead of the remnants of Fred, a slow-moving frontal zone and tropical moisture spreading north ahead of Fred allowed for a pre-cursory heavy rainfall event on August 17. This set the stage for later flooding as moisture more specifically associated with Fred advanced into the area during the next two days. A large swath of moderate to heavy rain moved in on August 17 and continued through the next morning. This resulted in impressive 24 hour totals across the area with greatest amounts in Allegany, Ontario, Wayne, and Lewis counties.
