The worst river flooding in Radford's recorded history occurred on August 14, 1940 with a slow-moving tropical depression. The 1940 hurricane season produced eight storms, four of which were hurricanes. Around August 5 of that year, a tropical storm was detected along the northern Leeward Islands in the West Indies. The storm brought wind gusts of 44 mph to San Juan, Puerto Rico as it moved northwestward. By August 6 it began a turn to the north while producing rough seas in the southeastern Bahamas. Four days later on August 10 the S.S. Maine off the southeast coast measured hurricane-force winds and the storm began movement again toward the northwest. The storm made landfall as a category 1 hurricane on August 11 at approximately 4 PM near Beaufort, South Carolina (along the SC/GA border). Winds reached 73 mph in nearby Savannah, Georgia.
