Much of the devastation thus far has focused on areas from Arkansas to Kentucky, killing at least eight people in four states across the region.

Natural disasters like heat waves, fires, and floods are growing more dangerous because of climate change, but the effect a warming world has on tornadoes is complicated and inconclusive.

An average of 1,200 tornadoes hit yearly, and the United States will probably get more killer supercells spawning tornadoes and hail as the world warms

After hail, heavy rains and more than 30 tornadoes drenched the region, officials warned that a “generational flooding” disaster was possible.

Tornadoes are expected to touch down in parts of the U.S. South on Friday, from northeastern Texas and southeastern Oklahoma into western and central Arkansas.

Tornadoes and violent winds flattened homes and ripped apart buildings from Oklahoma to Indiana in the first round of storms that are expected to bring record-setting rains and life-threatening flash floods across the nation's midsection in the coming days.

Last Sunday, 10 tornadoes hit Michigan, the most in a single day in 18 years. But it's not the most all time for the state.

Southeast and East Texas face a threat Saturday as a cold front with storms are expected. The storms could be severe and include hail and tornadoes.

Researchers are working to determine if there is any relationship between climate change and the number and severity of tornadoes

The Enhanced Fujita Scale is a tornado rating that determines the wind speed by the damage the tornado produces but do we need to adjust it?
