(April 11, 2016) – Today marks the 51-year anniversary of the deadliest tornado outbreak in Indiana history.

On April 11, 1965, 137 Hoosiers died as a swarm of 10 tornadoes wreaked havoc on 18 counties in the course of just a few hours.

84 people died in Elkhart County, and an 800-yard wide tornado killed 25 people near Kokomo.

There were so many tornado reports that for the first and only time in US history a Blanket Tornado Warning was issued.

Following that deadly tornado outbreak, the National Weather Service underwent changes to improve severe weather forecasts and warnings, including establishing the Watch and Warning Program that exists today and the weather spotter program, SKYWARN.

This photo acts as a good reminder to have a severe weather plan in place.
