A powerful storm system will bring several life-threatening weather hazards to Tennessee starting Wednesday night, including the threat of flash flooding and tornados, warns the National Weather Service.

Several central U.S. states were hit by deadly flash flooding and tornadoes overnight. Tennessee has suffered widespread damage in storms' wake.

Multiple videos shared on social media show powerful tornadoes touching down and leaving a trail of destruction in their wake.

There is a low chance of severe weather Friday, according to the National Weather Service. However, Middle Tennessee is not in the clear just yet.

It's been a long week of severe weather with a major tornado outbreak Wednesday night bringing at least 2 EF3 tornadoes.

A "slight" threat of severe weather continues for Middle Tennessee Thursday, the National Weather Service says, after a round of storms brought damaging winds and heavy rain.

Parts of the Midwest and South are facing the possibility torrential rains and life-threatening flash floods. The fresh storms on Friday come as many communities are still reeling from severe tornadoes that destroyed whole neighborhoods and killed at least seven people.
