At least 30 people have now died in the Appalachia region of eastern Kentucky, as the region braces for more rainfall.
At least six children – including four siblings, aged one to eight, who were reportedly swept from their parents’ grip – were among the dead.
Kentucky Governor, Andy Beshear, said the death toll would continue to rise as “hundreds” remain unaccounted for.
More than 12,000 households remain without power, and hundreds of homes and businesses have been flooded.
The damage to roads, bridges and other infrastructure will take millions to repair, the governor said on Monday.
Mr Beshear, who toured some of the hardest-hit neighbourhoods over the weekend, said he had seen “houses swept away” and “schools ruined”.
This was the worst flash flooding the region had seen in decades.
Governor Beshear called the flood “the deadliest and the most devastating of my lifetime”.
Displaced locals have taken refuge in state parks, churches and mobile homes brought in by the state.
Many people “only have the clothes on their backs,” Mr Beshear said. “Everything is ruined.”
Scientists say climate change was triggering more extreme weather events such as the Kentucky flooding.
President Joe Biden has declared the floods “a major disaster” and ordered federal aid to help local rescuers.
Two people have been found dead amid the huge wildfire sweeping through northern California which has forced thousands from their homes.
The bodies of the dead pair were found inside a car in the driveway of a property caught in the blaze.
Siskiyou County Sheriff, Jeremiah LaRue, told ABC News the two seemed to be trying to escape the area.
The McKinney Fire had burned more than 50,000 acres, making it California’s largest this year.
The identities of the two dead people would not be released until their families have been notified.
California’s Governor, Gavin Newsom, has declared a state of emergency over the fire, which began on Friday afternoon before rapidly exploding in size due to a combination of dry fuel after a drought, strong winds and lightning strikes.
Hundreds of firefighters were battling to contain the fire, but with little success. Sheriffsaid on Sunday evening that it was “0 per cent contained”. -BBC
