Tornado Outbreak, December 10–11, 2021

On the night of December 10-11, 2021, an outbreak of powerful tornadoes tore through parts of Arkansas, Mississippi, Missouri, Kentucky, Tennessee, and Illinois, killing dozens of people and leaving wreckage over hundreds of miles.

The Kentucky region was most affected, with more than 80 confirmed dead.  Extensive property damage has been reported, possibly making the storm the deadliest since 1890, when 79 people lost their lives in an area around Louisville.

The report shows that one tornado travelled 240 miles across four states, giving the tornado the nickname “Quad- State Tornado”.

As of 12 December, at least four EF-3 and five EF-2 tornadoes have been confirmed. EF-2 and EF-3 tornadoes are considered strong, with 111-135 mph and 136-165 mph wind speeds, respectively (see table).
