At least 16 people were killed in floods in the US state of Tennessee.
As the local media reported, citing information from the authorities, dozens of people were still missing on Sunday.
In the state in the southern United States, heavy rain caused flooding on Saturday.
The weather service spoke of "historical" rainfall.
The rescue and clean-up work continued on Sunday, as the local newspaper The Tennessean reported.
The 16 deaths were recorded by the civil protection in Humphreys county west of Nashville.
To prevent looting, the authorities imposed a night curfew.
The storm moved "almost as fast as a tornado" over the region in central Tennessee, said the mayor of the city of Waverly on local broadcaster WKRN.
Torn away cars and streets covered with mud were shown on television.
In addition to Humphreys and Waverly, the districts of Dickson, Hickman and Houston are also badly affected by the floods, the civil protection agency said. Between 22 and 43 centimeters of rain fell within six hours on Saturday morning. The storm only subsided during the night.
