Recent research has warned that extreme rainfall will be even more frequent due to climate change.

A record rainfall in Tennessee, US, caused massive flooding in rural areas that washed away homes, destroyed roads and  left  at least 22 people dead and dozens missing , including children and the elderly, authorities announced.

Saturday’s storm toppled trees, destroyed houses, and dumped cars into ditches, on top of sheds and other structures.

Through Sunday, rescue teams have remained in search of the missing people amid the rubble. In addition, the Waverly Department of Public Safety has published on official social media pages a list of residents of the neighborhoods most affected by the floods, whose whereabouts are still unknown.
