early the next morning severe thunderstorms spawned 31 tornadoes in
Alabama, Mississippi, Georgia and Tennessee. The tornadoes killed 334
persons and injured 1784 others. Northern Alabama was hardest hit.
Tornadoes in Alabama killed 286 persons and caused five million dollars
damage. (David Ludlum)
Severe thunderstorms spawned thirty-one tornadoes across Arkansas,
Tennessee, Missouri, Mississippi, Alabama and Kentucky. The tornadoes
killed 343 persons and caused 15 million dollars damage. Arkansas and
Tennessee each reported thirteen tornadoes. The towns of Judsonia AR and
Henderson TN were nearly wiped off the map in what proved to be the worst
tornado outbreak of record for Arkansas. A tornado, one and a half miles
wide at times, left a church the only undamaged building at Judsonia.
