Weather History for March 19
 
1952   A total of 151.73 inches of rain fell at Cilaos, Reunion Island, to set the world rainfall record for a five-day period.
1925   The great Tri State Tornado struck Missouri, Illinois, and Indiana. The F5 tornado stayed on the ground for 219 miles from Ellington, Missouri to Owensville, Indiana. Killing 695 people, it was the deadliest tornado in U.S. history. For three and a half hours, the tornado destroyed farms, homes, and schools. Virtually all of Gorham, IL was destroyed, and over half of its population was killed or injured. Griffin, IN lost 150 homes, and some children were killed on their way home from school.
